F16K31/385 - CPC Classification

Classification description:

Operating means Actuating devices; ; Releasing devices actuated by fluid in which fluid from the circuit is constantly supplied to the fluid motor in which the fluid works directly on both sides of the fluid motor, one side being connected by means of a restricted passage and the motor being actuated by operating a discharge from that side the fluid acting on a diaphragm
