摘要： In a pump apparatus having a reduction chamber for reducing pulsation of a hydraulic fluid pressurized in a pump section on the way of a discharge channel having an opening in the outer surface of the housing of the pump section, a remaining fluid inflow prevention pipe having one end fitted into and fixed to the discharge channel between the outer surface and the reduction chamber and the other end positioned in the reduction chamber is provided, and a seal lip for fluid-tightly sealing the space between the inner wall of the discharge channel and the one end is provided on the outer circumference of the one end. The seal lip is formed in a shape tapered toward the discharge side. Further, the outside diameter of the other end of the remaining fluid inflow prevention pipe is made larger than the inside diameter of the discharge channel.

摘要： A power steering apparatus integrally comprises an electric motor, a hydraulic pump driven by the electric motor, and a controlling device which is disposed between the electric motor and hydraulic pump and which controls the electric motor, in which steering is assisted by oil pressure generated by the hydraulic pump, wherein a radiating body for radiating a heat generated by the controlling device is disposed between the controlling device and hydraulic pump, so that the heat generated by the controlling device is radiated to the hydraulic pump. With this configuration, it is possible to efficiently radiate a heat generated inside the controlling device, the heat radiation can be designed without being influenced by ambient condition, and it is possible to be replaced by, member having a low heat-resistance.

摘要： A flow control apparatus is disclosed which includes a housing, a cylinder disposed in the housing and a spool disposed in the cylinder while being urged in one direction along the axial direction of the cylinder. The spool slides along the axial direction against the urging force, to adjust the flow quantity of a fluid. A stopper is disposed in the housing for restricting the range of the sliding movement of the spool toward the urging direction. A pair of engaging projections are disposed on the peripheral wall of either the housing and the stopper and are separated from each other by substantially 180 degrees, and an engaging hole disposed in the other of the peripheral wall and the stopper so as to engage at least one of the engaging projections. This at least one projection is engaging with the engaging hole by the urging force acting on the spool, to attach the stopper to the housing.
