Claims

[Scope of utility model registration request]

(1) Equipped with two sets of pumps and a pump body that integrally incorporates these pumps, and this pump body:
A pump housing space is formed to house a pair of pump cartridges consisting of a rotor having a plurality of vanes constituting each of the pumps and a cam ring housing the rotor. A first pump comprising a front body having a cylindrical portion that closes an opening and disposed on the bottom side of the pump housing space.
In a pump device, a pump is connected to a fluid device, and a second pump disposed on the opening side of a storage space is selectively connected to either the fluid device or the tank by a flow path switching valve. , the bottom outer diameter of the annular groove formed on the outer periphery of the cylindrical portion of the front body and communicating with the discharge side pressure chamber of the second pump is formed to be equal to or larger than the cam ring outer diameter of the second pump. A pump device characterized by:

(2) A side plate interposed between a pair of pump cartridges has a communication connection for guiding the hydraulic pressure on the back side of the vane of the pump cartridge constituting the first pump to the back side of the vane of the pump cartridge constituting the second pump. The pump device according to claim 1, characterized in that a hole is formed.
