Abstract

PURPOSE: To increase the volume of a high-pressure chamber, the circulation amount of oil, the surface area of a lip seal, and the cooling effect by providing the lip seal with a recessed groove.
CONSTITUTION: A recessed groove 26 is cut in the side face of a lip seal 16 on the side of a high-pressure chamber 25. A side plate 10 is formed with a through hole 28 in the position corresponding to a shut-up chamber 27 formed on the engagement of gears 4 and 5, while a cover 2 is formed with an introduction groove 29 communicating the hole 28 with the chamber 25. With a pump operated, the oil in the chamber 27 circulates through the hole 28 and the groove 29 to the chamber 25, flows through a lead out groove 30 to a high-pressure recess 15, and flows out into a discharge port 14. Thus forming the groove 26 in the seal 16 increases the volume of the chamber 25, the surface area of the seal 16, and the cooling effect.
