る。」と補正する。Amendment 1.5.12. The brief description of the drawing is amended as follows. In lines 9 to 12 of page 14 of the specification, it is stated that ``Figure 2 is a cross-sectional view taken along line NN in Figure 1 of the variable displacement oil pump according to the embodiment of the present invention. This is a variable capacity oil pump.
", "Figure 2 is a detailed view of the swing vane in Figure 1. Figure 3 is a NN cross-sectional view in Figure 1 of the variable displacement oil pump according to the embodiment of the present invention. Figure 4 is a conventional variable displacement oil pump.''

Claims

[Claims for Utility Model Registration] (1) A rotor that supports a plurality of vanes, a cam ring that accommodates the rotor eccentrically within its inner circumference and rotates around a point offset from the center of the inner circumference, and the cam ring. Equipped with an actuator that rotates and adjusts the
In a variable displacement oil pump, the amount of eccentricity between the inner periphery of the cam ring and the rotor is controlled by rotating the cam ring by the actuator, thereby controlling the discharge amount of the pump relative to the pump discharge pressure. A variable capacity oil pump in which the vane is swingably held by a plurality of groove-shaped fulcrums provided on the outer periphery. (2) The variable displacement oil pump according to claim 1, wherein each vane has a plurality of contact points with the cam ring. (3) The variable displacement oil pump according to claim (2), further comprising a sliding ring close to the outer end of the vane and close to the inner peripheral surface of the cam ring.
