Title:
SWASHPLATE TYPE PISTON PUMP
Document Type and Number:
WIPO Patent Application WO/2018/008209
Kind Code:
A1
Abstract:
The swashplate type piston pump (1, 90) comprises: a cylinder block (3) which rotates with the rotation of a drive shaft (5); multiple pistons (8) which are accommodated inside multiple cylinders (6) disposed in the cylinder block (3); a swashplate (4) for causing the pistons (8) to move back and forth so as to expand/contract volume chambers (7) of the cylinders (6) with the rotation of the cylinder block (3); a biasing mechanism (21, 22) for biasing the swashplate (4) in a direction in which the tilt angle thereof increases; a control pin (30) for driving the swashplate (4) in a direction in which the tilt angle decreases in response to an increase in load pressure of a pressure chamber (42); and a discharge flow path (53, 54) for releasing the load pressure of the pressure chamber (42).
