Title:
VARIABLE DISPLACEMENT VANE PUMP AND POWER STEERING SYSTEM USING THE SAME
Document Type and Number:
Japanese Patent JP2004218528
Kind Code:
A
Abstract:
To reduce energy loss by optionally controlling the discharge according to the required quantity of flow on the load side.
This variable displacement vane pump is constituted to change the discharge according to the eccentric amount of a cam ring 4 variable in the eccentric amount and built in a body 1, is provided with a solenoid 48 equipped with an axially movable rod 47, and a controller 51 for controlling the solenoid, and constituted to transmit the motive force of the rod to the cam ring.
