量形ポンプの流量制御回路。 The regulator of the variable displacement pump connects the secondary side port of the relief valve that regulates the discharge pressure of the variable displacement pump to the tank via the throttle valve, and uses the pressure upstream of the throttle valve as the pilot pressure for controlling the pump flow rate. In what was designed to lead to
A flow rate control circuit for a variable displacement pump, characterized in that an accumulator is disposed in a passage that leads the pilot pressure to a regulator.
