Abstract: In a swash plate type hydraulic system such as a hydraulic pump, a hydraulic motor of the like, a group of cylinder bores in which plungers engaging a swash plate are slidably received are annularly arranged in a cylinder block, and higher and lower pressure oil passages are concentrically provided in the cylinder block. Further, a group of distributor valves are provided in the cylinder block in a radially arranged configuration for controlling the connection and disconnection between the higher and lower pressure oil passages and the group of cylinder bores by radial reciprocating motion of the valves, and an eccentric wheel is provided eccentrically with respect to the center of rotation of the cylinder block to abut against the outer ends of the distributor valves so as to impart a reciprocating motion to each of the distributor valves. A shifting device is provided for changing the eccentric relationship between the eccentric wheel and the cylinder block.

TL;DR: In this paper, the authors proposed a method to prevent the increase of the length in the axial direction of a block by arranging a number of clutch valves which move in reciprocation between the inner and outer positions in the radial direction and short-circuit the inside and outside oil passages in the case when the troke becomes over a certain value, alternately with the second distribution valve, on a cylinder block.
