タンデムポンプを有する流体圧装置。 The fluid stored in the reservoir is sucked in through the first and second suction pipes by a tandem pump consisting of a first and second pump, and the fluid is sucked in through the supply pipe from the tandem pump, which has a different consumption flow rate. In a fluid pressure device configured to supply fluid to a pressure response device, a first return pipe for recovering a return flow from the first pressure response device with a large consumption flow rate is connected to the reservoir; A second return pipe for recovering the return flow from the second pressure-responsive device is connected to the first suction pipe on the first pump side. 1. A fluid pressure device having a tandem pump, characterized in that a drawing passage is formed to draw in the tandem pump.
