PROBLEM TO BE SOLVED: To prevent a size increase of a swash plate type piston pump responding to a plurality of load pressures.SOLUTION: The swash plate type piston pump 1 capable of changing a discharge capacity according to load pressure includes: guide members (an inner guide cylinder 41, an outer guide cylinder 42) which are protruded from a port block 50; a first control pin 31 which is supported on the guide members in a slidable manner to drive a swash plate 4 in a direction of reducing a tilt angle according to a first load pressure (the discharge pressure of a piston pump 80); and a second control pin 32 which is supported on the guide members in a slidable manner to drive the swash plate 4 in the direction of reducing the tilt angle according to a second load pressure (pilot pressure). |
