摘要： A variable capacity piston pump 1 comprises a control piston 50 pressing a pressed portion 33 of a swashplate 30 from a cylinder block 14 side to adjust an inclination of the swashplate 33 between a maximum inclination and a minimum inclination, and a swashplate return spring 60 biasing the pressed portion 33 of the swashplate 30 toward the cylinder block 14 side of the sliding contact surface 30a, wherein there is a positional relationship in which a vertical reference line Z passes between a first seat surface center position A1 of the swashplate return spring 60 when the swashplate 30 is at the maximum inclination and a second seat surface center position A2 of the swashplate return spring 60 when the swashplate 30 is at the minimum inclination.

摘要： A variable capacity piston pump 1 comprises a piston portion 58 of the control piston 50 causing a pressing force to act along one direction by pressing a pressed portion 33 of a swashplate 30 from a cylinder block 14 side to adjust an inclination of the swashplate 30 between a maximum inclination and a minimum inclination, and a swashplate return spring 60 biasing the pressed portion 33 of the swashplate 30 toward the cylinder block 14 side of the sliding contact surface 30a, wherein there is a positional relationship in which a vertical reference line Z passes between a first action position A1 which is an action position of the pressing force when the inclination of the swashplate 30 is the maximum inclination and a second action position A2 which is an action position of the pressing force when the inclination of the swashplate is the minimum inclination.

摘要： A hydraulic pump having a rotary shaft rotatably supported with respect to a casing, the hydraulic pump including: a bearing part provided to one end side and the other end side of the rotary shaft; and a first annular member provided around the rotary shaft on at least one side of the one end side and the other end side of the rotary shaft. The bearing part on the one side has a support part which rotatably supports the rotary shaft, and a preload applying member which applies a preload in the axial direction to the support part. The first annular member is interposed between the bearing part of the one side and a receiving part of the rotary shaft in the axial direction, and an inner diameter of the first annular member is larger than a diameter of the rotary shaft.
