  • Publication number: 20240369060
    Abstract: In a variable displacement oil pump (VP1) according to the present invention, a coil spring (SP) as an urging member is arranged at a position that does not overlap a first suction port (114), a first discharge port (115) and an inlet (124a) which correspond to a suction portion when viewed from an axial direction along a drive shaft (2). Therefore, in the variable displacement oil pump (VP1), there is no risk that during pump operation, flow of oil introduced into the pump chambers 30 located in a suction region through the first suction port (114), the first discharge port (115) and the inlet (124a) corresponding to the suction portion will be interrupted by the coil spring (SP). With this, in the variable displacement oil pump (VP1), a suction resistance during the pump operation is reduced, then a suction performance of the pump can be improved.

  • Publication number: 20240352932
    Abstract: In a variable displacement oil pump (VP1) according to the present invention, a stopper portion (45) that can come into contact with a cam ring contact portion (112e) provided at a pump accommodating portion (110) is provided at a position that does not overlap a first suction port (114), a second suction port (124) and an inlet (124a), which correspond to a suction portion, in a circumferential direction of rotation of a drive shaft (2) on a rotation center (Z). Therefore, there is no risk that flow of oil sucked into pump chambers (30) located in a suction region through the first suction port (114), the second suction port (124) and the inlet (124a) will be interrupted by the stopper portion (45), thereby improving a suction performance of the pump.
