Abstract

PURPOSE: For preventing the decrease of efficiency, to reduce the pressure change of working oil in the hollow portion of a plunger by forming a throttle hole in the rear end portion of said plunger.
CONSTITUTION: If a throttle hole 11 is provided in the rear end portion of a plunger 4, working oil in a cylinder 2 is led to a lubricating oil reservoir 8 through said throttle hole 11, a hollow portion 4, a communicating hole 10 and a throttle hole 9, and between a shoe 6 and a swash plate 7 for lubrication. Therefore, said throttle valves 9 and 11 are not required to be reduced extremely in diameter since throttling is performed in two steps thereby. Consequently, the propability of the clog of said throttle valves 9 and 11 with dust, the inflow and outflow of working oil of said hollow portion 4, and air accumulation in said hollow portion 4 decrease. Further, even if air bubbles are generated, the influence of outside pressure change on said hollow portion 4 and the decrease in operational efficency of this hydrualic system are prevented.
