Тарельчатые клапаны 14 и 16 управл ютс  при помощи упругодеформируемого элемеита 19, который в соответствии с температурой измен ет свою длину. При этом тарель- 50 чатые клапаны могут нерекрывать отверсти  15 и 17. Смесительна  камера 20 термостата таким образом соединена как с радиатором, так и С вод ной рубашкой.To the bottom of the nozzle of the radiator 7 there is a connection of a diverter pipe 13, which is connected to the thermostat housing. This pipeline. Can be completely or partially blocked by the disc valve 14, blocking the hole 15; The disc 40 valve 14 and the disc valve 16, which is designed to open or close the control opening 17 of the radiator bypass 18, are parts of a three-way thermostat located 45 in the inner space of the housing 9. The disc valves 14 and 16 are controlled by an elastically deformable element. 19, which changes its length according to temperature. In this case, the plate valves may not open the holes 15 and 17. The thermostat mixing chamber 20 is thus connected to both the radiator and the water jacket.

К смесительной камере 20 нодеоединен 55 впускной трубоировод 21 насоса 22, который подает хладагент но напорному трубопроводу 23 через отверстие 4 в иервую зоу 2 охлаждающей рубашки двигател  1. Кроме того, смесительна  камера 20 сое- 60 инена с расширительным баком 24 при иоощи воздуховыиускиого трубопровода 25.To the mixing chamber 20, there is a single inlet 55 of the inlet pipe 21 of the pump 22, which supplies refrigerant to the discharge pipeline 23 through the opening 4 to the open hole 2 of the cooling jacket of the engine 1. In addition, the mixing chamber 20 is inena 20 with the expansion tank 24 at the air outlet of the exhaust pipe 25 .

Чтобы при заполнении системы охлаждеи  хладагентом избежать проникновени  узырьков воздуха, которые угрожали бы б5So that when filling the cooling system with refrigerant, to avoid penetration of air streaks that would threaten

иадежной экснлуатации насоса 22, а также охлаждеиию зон сгорани , в верхних точках системы предусмотрены вентил циониые каиалы. Дл  вентил ции радиатора 7 к его верхней точке нодсоединен вентил ционный канал- 26, подключенный к полости кориуса термостата в зоне, расположенной между отверстием 15 и трубопроводо.м 13 н нрнмыкающей к месту подключени  воздуховыпускного трубопровода 25. К этой же точке ир1имыкает второй вентил ционный канал 27, предназначенный дл  вынуска воздуха из верхней точки смеснтельной камеры 20 термостата.In addition to the safe operation of the pump 22, as well as cooling of the combustion zones, ventilation systems are provided at the top of the system. To ventilate the radiator 7, a ventilation duct 26 is connected to the upper point of the radiator in the zone located between the aperture 15 and the pipeline 13 on the outlet side 25. The second ventilation duct is located at the same point channel 27, designed to exhaust air from the top of the thermostat mixing chamber 20.

Воздуховынускной трубопровод в стыке с корпусо термостата выполнен в виде предусмотренной в корпусе полости с поплавковым клапаном 28. При повышении уровн  жидкости в нолости иоплавковый клапан всплывает и иерекрывает впускное отверстие трубоировода 25. Вентил ционные каналы 26 и 27 при этом также отключаютс  от расширительного бака. Циркул ци  хладагеита по вентил ционным каналам в расширительный бак и возврат его из бака в систему исключаютс , что обеспечивает ускоренный прогрев хладагента в замкнутом объеме. С этой же целью во врем  нрогрева полость смесительной камеры 20 замкнута тарельчатым клананом И, а радиатор 7 - тарельчатым клапаном 14.The air flue pipe in the junction with the thermostat housing is designed as a cavity provided in the housing with a float valve 28. When the liquid level increases in the floor, the float valve floats and overlaps the inlet of the pipeline 25. The ventilation channels 26 and 27 are also disconnected from the expansion tank. Circulation of refrigerant q through the ventilation ducts into the expansion tank and its return from the tank to the system are eliminated, which ensures accelerated heating of the refrigerant in a confined space. With the same purpose, during heating, the cavity of the mixing chamber 20 is closed with a disk-shaped clan, and the radiator 7 - with a disk-shaped valve 14.

Расширительный бак сообщен с системой циркул ции хладагента ири помощи трубы 29, иодключеииой к его нижней точке и к корпусу термостата. Если клапан 11. закрыт , циркул ци  хладагеита по этой трубе исключена.The expansion tank communicates with the circulating refrigerant circulating system using a pipe 29 and connecting it to its lowest point and to the thermostat housing. If valve 11 is closed, circulation of refrigerant through this pipe is excluded.

Корпус термостата, изображенного на фиг. 2 и 3, нредставл ет собой литую деталь , котора  изготовлена иреимуществеино из алюмини  или других известных сплавов легких металлов. Он состоит из собственно корнуса 30 и крышки 31, котора  кренитс  к кориусу болтами 32. Между поверхност ми сопр жени  кориуса и крышки кориуса иредусмотрено уплотнение 33.The case of the thermostat shown in FIG. 2 and 3, is a cast part that is made of aluminum or other known alloys of light metals. It consists of the actual Cornus 30 and the Lid 31, which rolls toward the corus with the bolts 32. Between the mating surfaces of the corus and the lid of the corius there is a seal 33.

Кориус 30 дл  кренлени  к двигателю снабжен фланцем с крен щими ушками 34 и 35. Кроме того, он имеет соедииительные штуцеры 36-38 дл  трубопровода 6 хладагента , трубы 29 и впускного трубопровода 21 насоса.Krenius corus 30 to the engine is equipped with a flange with heeling ears 34 and 35. In addition, it has connecting fittings 36-38 for refrigerant pipe 6, pipe 29 and pump inlet pipe 21.

На крышке 31 дл  отвод щего трубопровода 13 радиатора нредусмотрен соединительиый штуцер 39. Дл  выпуска воздуха I корпусе термостата и его крышке предусмотрены вентил циоиные каналы 26 и 27. Воздуховыпускной трубоировод 25 соединен с клапаном 28 нри помощи сверлени  в крышке, от этого сверлени  ответвл етс  канал 27.The cap 31 for the radiator outlet pipe 13 is provided with a connecting nipple 39. Ventilation channels 26 and 27 are provided for air release to the thermostat case I and its cover. The air outlet pipe 25 is connected to the valve 28 by means of drilling in the cover, the channel is separated from this hole 27.

Соединительные штуцеры на крышке служат дл  подсоединени  вентил ционных каналов 26 и 27 к расширительному баку и к радиатору.The connecting nipples on the cover are used to connect the ventilation ducts 26 and 27 to the expansion tank and to the radiator.

Поплавковый клапан 28 имеет конический участок 40 и цилиндрическую направл ющую часть 41. Седло 42 клапана выполнено в виде полого конуса. К седлу клапана подсоедин ютс  вентил ционные каналы , например сопр жение с каналом 27 показано в виде отверсти .The float valve 28 has a conical section 40 and a cylindrical guide part 41. The valve seat 42 is designed as a hollow cone. Venting channels are connected to the valve seat, for example, mating with channel 27 is shown as a hole.

Как только при заполнении системы охлаждени  хладагентом уровень хладагента достигает поплавкового клапана, последний прижимаетс  к поверхности седла 42. Этим предотвращаетс  проникновение хладагента в воздуховыпускной трубопровод 25 и исключаетс  циркул ци  хладагента по вентил ционным каналам 26 и 27 через расширительный бак 24, трубу 29, корпус термостата и зоны 2 и 3 охлаждающей рубашки двигател  1.As soon as the refrigerant system is filled with the refrigerant level, the refrigerant level reaches the float valve, the latter is pressed against the surface of the seat 42. This prevents the refrigerant from entering the air outlet pipe 25 and prevents the refrigerant from circulating through the ventilation ducts 26 and 27 through the expansion tank 24, pipe 29, thermostat housing and zones 2 and 3 of the engine cooling jacket 1.

Таким образом, обеспечено быстрое нагревание двигател  без замедл ющего вли ни  циркул ции хладагента через расширительный бак.In this way, the engine is quickly heated without slowing down the circulation of the refrigerant through the expansion tank.
