Abstract: A valve block in a mine hydraulic system contains a non-return valve which is opened when a hydraulic control signal occurs to connect a pressure fluid feed or return line to a working chamber of an appliance such as a prop. A auxiliary valve is mounted in the block and is operated manually to relieve the working chamber even if the non-return valve remains closed.

Abstract: A check valve (14) with a valve opening actuator and a bypass passage (16) are disposed in parallel in a pressurized oil supply/discharge passage (3) connected in communication with a hydraulic actuation chamber (2). A residual pressure holding valve (17) and a flow restrictor (21) are disposed in series in the bypass passage (16). The supply/discharge passage (3) and a discharge passage (7) are connected in communication by a pressure compensation valve (12). While the valve (17) is adapted to be moved to a valve closing position by means of pressure supplied at a check valve inlet (14a) and a residual pressure holding spring (19), it is adapted to be moved to its valve opening position by means of pressure supplied at a check valve outlet (14b). The valve (17) includes a valve member (38) resiliently urged to a valve seat (40) by means of a spring (19).

Abstract: Safety valve for a hydraulic circuit supplying a hydraulic receiver having an inlet and an outlet connected to the receiver which includes between the inlet and the outlet a non-return module which has a non-return valve and a selectively operable valve having an unoperated position in which the non-return valve prevents any reverse flow of fluid from the outlet to the inlet and an operated position in which such reverse flow is made possible. A control inlet is provided for applying control pressure to the selectively operable valve. A pressure relief valve is provided between the outlet and the control inlet which is adapted to enable flow from the outlet to the control inlet from a predetermined pressure threshold.

Abstract: The piloted valve has three abutment surfaces for controlling the positions of the pilot lid and main lid. The abutment surfaces are disposed relative to each other so that the maximum stroke of the pilot lid relative to the casing is greater than the maximum stroke of the pilot lid relative to the main lid and less than the sum of the maximum stroke of the pilot lid and the maximum stroke of the main lid relative to the casing. With the pilot lid open and the main lid closed, a large flow cross-section is available; however, closing of the pilot lid with the main lid open requires only a very short stroke. The resulting valve operates very rapidly.

Abstract: There is disclosed a spool type direction control valve for controlling the oil flow direction in a hydraulic circuit including a pressure source, a hydraulic cylinder and a spool member. A flow control mechanism is provided in an oil passage connecting one of the oil chambers of the hydraulic cylinder to the spool member. The flow control mechanism comprises a poppet type piston adapted for opening and closing the oil passage. When the spool member is switched over for supplying the pressure fluid to the other oil chamber of the hydraulic cylinder, the pilot pressure from the pressure source is caused to act on the piston in the valve opening direction, while the back pressure of the discharge side pressure fluid corresponding to the load acting on the one oil chamber is caused to act on the piston in the valve closing direction, so as to control the discharge flow of the pressure fluid from the one oil chamber.

Abstract: An orifice controlled poppet valve includes a pilot poppet pressure balancing arrangement which prevents fluid leakage between the valve inlet and outlet. The pressure balancing arrangement includes a pin slidable in a passage in the main valve member, which passage extends between the inlet and a pilot outlet passage. One end of the pin engages a stem which projects from from the pilot poppet. The other end of the pin engages a flexible diaphragm which forms a seal between the valve inlet and the passage which receives the pin. An inlet pilot passage includes an annular clearance upstream of an orifice. The radial dimension of the annular clearance is smaller than the diameter of the orifice.

Abstract: A hydraulic piston cylinder device comprising a cylinder, a piston dividing the cylinder into two cylinder spaces (A and B), and valve members between the cylinder spaces and respective pressure medium pipes. The problem is to achieve a hydraulic piston cylinder device in which the pressure or tractive force of the cylinder is maintained even if the external pressure led into the cylinder would stop. To solve this problem, an elastic material is interposed between two piston parts, and is elastically compressible by the external pressure applied to the cylinder; and the valve members are coupled to each other so that when one of the valve members is closed the other cannot be closed.
