Abstract
PURPOSE: To avoid oil leakage in a high-pressure oil feed pipe by pressure contacting the end face of a cylinder piece with the tip end face of a high-pressure oil feed pipe utilizing the high oil pressure in a discharge line.
CONSTITUTION: When a high oil pressure is discharged into a high-pressure oil feed pipe 43 arranged in the axial direction of a pump chamber, the high-pressure oil discharged into a discharge line 33 pressure contacts a cylinder piece 50 with a pressure contact ring 49 fitted to the tip end face of the pipe 43, before discharged to a discharge port through an oil feed line 46 inside the pipe 43. Thus, there is obtained a very high tightness and the oil from the line 33 can be transferred into the pipe 43 without leakage.
