Abstract

PURPOSE: To obtain an operation check valve with operation of a slow return valve, forming two orifices to connect the pressure chamber on the back side to the pressure chamber and the circuit on the cylinder side respectively in a poppet valve.
CONSTITUTION: A push rod 13 of a piston 8 presses the poppet valve 23 rightward against the spring 24 for a stroke of l1-l2 to open a passage and a valve hole 3. Thereby, the returning oil in other oil chamber 18 in the cylinder 16 flows into the pressure chamber 3a through a port 21, an orifice 26, a pressure chamber 3b and an orifice 25, the returning oil from the pressure chamber 3a is returned into the tank through a passage 4 and a port 22. Thus, at the compression stage of the cylinder, since the returning oil in the oil chamber 18 is constructed with an orifice 26, 25, its compression speed is controlled slowly.
