Abstract

A transfer device that includes a case that houses a transfer mechanism; a strainer that suctions oil stored in a lower portion of the case; a valve body that has a hydraulic supply circuit that supplies a hydraulic pressure to the transfer mechanism and a suction oil path that discharges an extra hydraulic pressure that is extra for the hydraulic supply circuit; a first suction inlet that communicates with one of the suction oil path and the strainer and a second suction inlet that communicates with the other of the suction oil path and the strainer, and a balanced vane pump.

Claims

1. A transfer device comprising:

a case that houses a transfer mechanism;

a strainer that suctions oil stored in a lower portion of the case;

a valve body that has a hydraulic supply circuit that supplies a hydraulic pressure to the transfer mechanism and a suction oil path that discharges an extra hydraulic pressure that is extra for the hydraulic supply circuit;

a first suction inlet that communicates with one of the suction oil path and the strainer and a second suction inlet that communicates with the other of the suction oil path and the strainer; and

a balanced vane pump that has;

a first suction port which faces the first suction inlet and into which oil flows from the first suction inlet,

a second suction port which faces the second suction inlet and into which oil flows from the second suction inlet,

a first discharge outlet and a second discharge outlet that discharge oil having flowed thereinto from the first suction inlet and the second suction inlet to the hydraulic supply circuit, and

a communication oil path disposed downstream of the first suction port and downstream of the second suction port to communicate between the first suction port and the second suction port.

2. The transfer device according to claim 1, wherein

the valve body is disposed on the opposite side of the vane pump from the strainer.
