7, to which a pressure body consumer is connected. A check valve 18 is arranged in parallel with the throttle 16, and a ball 19 serving as a valve body is pressed against a valve seat 21 by a spring 20. But instead of loading the ball 19 by the spring 2o, the piston 2
2 may be used, and the pressure in the delivery conduit 17 may be applied to this piston 22 through the branch line 23, and the blanker 24 provided on the piston 22 may be applied to the ball 19. This is indicated by a dashed line in Hayashi's drawing. In this way, the pressure loss caused by the check valve 18 is small.

によ゛り生ずる騒音も減衰せしめられる。When the motor 3 drives the pump 1, a pump pressure medium is generated in the pump working chamber 9, and the pressure medium reaches the casing passage 11 via the discharge valve 12. The casing 4 channel 11 leads directly to the Aki-West Muleta 2. Pressure shocks and pressure oscillations caused by the operation of the pump I are damped and smoothed within the pressure accumulator 13. Furthermore, any noise that may occur is also attenuated.
逆止め弁１８は特定の開放圧力を有しており。The check valve 18 has a certain opening pressure.
