Abstract: A pump device includes a first case, a second case, a sacrificial anode. The first case has a channel in which hydraulic fluid flows. The second case provides in contact with the first case. The sacrificial anode is coupled to one of the first case and the second case and suppresses corrosion of the first case and the second case. At least one of the first case and the second case includes an insulating section that interrupts electric coupling between the first case and the second case. The pump device further includes a valve member provided in the channel, controlling the flow of the hydraulic fluid flowing in the channel, and electrically coupling the first case and the second case.

Abstract: A pump apparatus includes a shaft, a first pump, and a second pump. The first pump includes a first driving gear disposed on the shaft in a first phase and rotatable with the shaft to feed a first operating fluid. The second pump includes a second driving gear disposed on the shaft in a second phase shifted from the first phase. The second driving gear is coaxial with the first driving gear and rotatable with the shaft to feed a second operating fluid.
