摘要： A pilot control valve for controlling a reciprocating pump has a valve member shiftable within a valve body between a first or “downstroke” position and a second or “upstroke” position. In its first and second positions, the valve member positions slide valves to allow communication of control fluid to move the piston to a second and first position, respectively. When the piston reaches its second position a poppet disposed in a rod attached to the piston allows control fluid acting on the valve member to depressurize. Pressurized control fluid then acts on the valve member to move to its second position. When the piston returns to its first position, the poppet allows pressurized control fluid acting on the upper surface of the piston to act on the valve member to move the valve member back to its first position and repeat the process.

摘要： An hydraulic switching valve (35) comprises, among other parts, a valve housing (45, 62) with a first connection (33, 36) and a second connection (34, 67) and a valve body (37, 63) which is movable in the valve housing (45). The switching valve (35) is open when the pressure at the first connection (33) is higher than the pressure at the second connection (34) as a result of the fact that the pressure difference caused by the movement of the valve body (37) allows a flow past the valve body (37). The switching valve is closed when the pressure at the first connection (33) is lower than the pressure at the second connection (34) as a result of the fact that the movement of the valve body (37) caused by the pressure difference closes a valve seal (40) which blocks the flow. The switching valve (35) further comprises a lock (39) with switching element (42) for selectively keeping the valve seal (40) closed, and unblocking the valve body (37), respectively.

摘要： A hydraulically powered gas compressor receives low pressure gas and outputs a high pressure gas. The housing of the compressor defines a cylinder with a center chamber having a cross-sectional area less than the cross-sectional area of a left end chamber and a right end chamber, and a spool-type piston assembly is movable within the cylinder and includes a left end closure, a right end closure, and a center body that are in sealing engagement with the respective cylinder walls as the piston reciprocates. First and second annular compression chambers are provided between the piston enclosures and center housing portion of the compressor, thereby minimizing the spacing between the core gas and a cooled surface of the compressor. Restricted flow passageways are provided in the piston closure members and a path is provided in the central body of the piston assembly, such that hydraulic fluid flows through the piston assembly to cool the piston assembly during its operation. The compressor of the present invention may be easily adapted for a particular application, and is capable of generating high gas pressures while maintaining both the compressed gas and the compressor components within acceptable temperature limits.
