Abstract

176,067. Rusdell, W. J. Nov. 16, 1920. Liquid-pressure engines.-A method of transforming the uniform rotary motion of a shaft &c. into uniform rectilinear motion of a liquid, or vice versa, consists in transmitting the motion through reciprocating pistons &c. operating in series and each in turn performing a power stroke of which a substantial portion occurs at a uniform velocity. In one form, the pistons 2<a>, 2<b> are actuated by cams 9<a>, 9<b> shaped to give uniform speed to the pistons during the delivery stroke. The liquid enters at 1 and passes through the valves in the piston 2<a> during the upstroke and is forced by this piston during its down stroke through the valves in the piston 2<b>. The piston 2b during its upstroke forces the liquid through the delivery 5. The periods of uniform speed of the piston may overlap, and the valves may operate during such overlapping. In another form, three pistons are arranged in series. The valves may be arranged in a wall of the pump instead of in the pistons. The pistons may be arranged coaxially in the cylinder, the rod of one piston passing through the rod of the other. Two pistons may be actuated by a single cam acting through levers pivoted to the piston rods, and may be returned by cams or by springs 10<a>, 10<b> or by liquid pressure acting on the ends of the piston tail-rods. The returning spring may move the fulcrum of a lever the two ends of which engage the tail-rods of the pistons, so that part of the power strode of one piston assists the return of the other. The cams may actuate the pistons oil casing having a removable cover. The invention is applicable to hydraulic motors by supplying a uniform flow of pressure liquid. The stroke may be varied by inserting between the cam and the pump-rod a lever with an adjustable fulcrum.
