プ駆動軸内に油圧通路を配設したオイルポンプ。 The pump has a pump drive shaft supported within a pump body via a bearing, a pump gear that is engaged with the pump drive shaft and rotates together with the drive shaft, and a pump pulley that is driven by an engine. In an oil pump in which the drive shaft is driven by the pump discharge pressure via a viscous fluid coupling with variable coupling efficiency, a spring fixed within the pump drive shaft is biased to move the drive shaft in the axial direction. A slidable rod is disposed within the shaft, and a divider plate that divides the interior of the fluid coupling into two chambers, a storage chamber and a torque transmission chamber, is fixed within the coupling, and the divider plate is configured to transmit the torque. A pump protrusion and a pump hole are provided to send viscous fluid from the storage chamber to the storage chamber, and a return hole is provided to communicate the viscous fluid from the storage chamber to the torque transmission chamber, and a lever with a valve body for opening and closing the return hole is provided. A hydraulic passage is provided in the pump body and the pump drive shaft so that one end of the rod contacts the divider plate and the pump discharge pressure acts on the other end surface of the rod. oil pump.
