Abstract

PURPOSE: To make a vane pump compact and cheap, by providing at least two pairs of suction and discharge ports, equalizing the interval between the suction and discharge ports to that between two vanes and enabling the connection and disconnection of the suction and discharge ports to and from a high and a low pressure chamber.
CONSTITUTION: At least two pairs of suction ports 16W18, 16AW18A and discharge ports 13W15, 13AW15A are provided. The interval between the suction and discharge ports ie equalized to that between two adjacent vanes 7. One of the second pair of suction and discharge ports is located between the first pair of suction and discharge ports. An opening/closing means 19 is provided to control the connection and disconnection between a required suction port and a low pressure chamber 3 and between a required discharge port and a high pressure chamber 4. As a result, the flow rate of discharge can be varied without changing the relative position of a rotor 6 and a cam ring 10. For that reason, a vane pump can be made compact and cheap.
