Abstract

PURPOSE: To provide a cylindrical surface seal of high PV value with an excellent characteristic of sealing, by providing a recessed groove in the sealing face with the both sides of the groove constructed cylindrical surfaces to constitute the sealing face.
CONSTITUTION: Through a casing 1 is penetrated a shaft 3 and in the inner circumferential part are firmly engaged a high molecular material made seal ring 4 and outer ring 5. The inner circumference of a lip 6 in the seal ring 4 is closely contacted to the periphery of the shaft 3 to constitute a seal face 7, and in the periphery of the lip 6 is engaged a spring ring 8, with its shrinking force made heightening a contact pressure to the seal face 7, and a recessed groove 9 is provided in the seal face 7 and a cylindrical surface 10 provided at the both sides. With the shaft 3 rotated, the dylindrical surface 10 constitutes a sliding seal with a fluid stored in the recessed groove 9, and a slight amount of fluid infiltrates from its both ends to the cylindrical surface 10 to lubricate the seal face. In this way, the seal face can hold a characteristic of highly sealing.
