摘要： Providing a seal member taking-out device which can successfully take out a larger number of seal members. The seal member taking-out device includes a shaft member, a cylinder member, a moving member, and a taking-out member. The shaft member is columnar or cylindrical. The cylinder member is cylindrical and the shaft member is inserted through the cylinder member so that the cylinder member is movable in a direction of a central axis of the shaft member. The cylinder member is shorter than the shaft member and extends in the direction of the central axis of the shaft member. The moving member moves a plurality of seal members stacked on the shaft member and the cylinder member, in a direction of a distal end of the shaft member. The taking-out member takes out the seal members from the distal end of the shaft member.

摘要： A vane pump includes: a rotor connected to a driving shaft; a plurality of vanes provided so as to be capable of reciprocating in a radial direction with respect to the rotor; a cam ring having a cam face on which a tip-ends of the vanes slide with the rotation of the rotor, the cam ring being provided so as to be capable of being made eccentric with respect to the rotor; a second pump body configured to accommodate the cam ring; and a spring interposed between the cam ring and the second pump body in a compressed state, the spring being configured to bias the cam ring in the direction in which the amount of eccentricity with respect to the rotor is increased. The cam ring and the second pump body have seating surfaces on which the spring is seated and grooves formed in the seating surfaces.

摘要： A damping valve includes a valve element member, a disc spring, and a solenoid. The valve element member opens and closes an upstream side and a downstream side of a pilot passage by a pressure control valve element seated on and liftable from a pressure control valve seat and an open/close valve element seated on and liftable from an open/close valve seat. The disc spring is interposed between a stepped part and the valve element member. The disc spring biases the valve element member in a direction in which the pressure control valve element separates from the pressure control valve seat and in which the open/close valve element approaches the open/close valve seat. The solenoid is configured to drive the valve element member against a biasing force by the disc spring. In a state in which the disc spring has a natural length, a clearance is formed between the open/close valve element and the open/close valve seat.
