摘要： A piston (600) includes a piston housing (601) and a decompression valve (620) disposed in the piston housing. The decompression valve includes a valve housing (630) seated in the piston housing and a valve member (640) moveably received by the valve housing. The valve member (640) has a radially outer surface including an annular shoulder. In addition, the piston includes an end cap (670) secured to the first end of the piston housing. A radially inner surface of the end cap includes an annular valve seat (674). The decompression valve has a closed position with the annular shoulder of the valve member engaging the valve seat of the end cap and an open position with the annular shoulder of the valve member axially spaced from the valve seat of the end cap. The piston also includes a biasing member (660a,660b,660c,660d) configured to bias the decompression valve to the closed position.

摘要： A compressor device for compressing a gas in at least one compression chamber in at least one compression cylinder is disclosed. In each of at least two drive cylinders, at least one drive piston is disposed, said at least one drive piston dividing each of the at least two drive cylinders into two drive chambers. The at least one first and second drive chamber, by way of a hydraulic fluid, are able to be periodically impinged with a fluid pressure in order for the respective drive piston to be moved. Each of the remaining drive chambers in the at least two drive cylinders, by way of a connection piece, are connected in a non-positive locking manner by a fluid. The movement of the drive pistons by way of at least one mechanical connection means is able to be transmitted to at least one compression piston.

摘要： A method for high fluid shear processing of a fluid uses an isolator that has a first sub-chamber for containing a first fluid and a second sub-chamber for containing a second fluid defined by a separator positioned in the chamber and movable between a first end of the chamber and a second end of the chamber. The two sub-chambers are in pressure communication with each other but are not in fluid communication with each other. A first fluid is pumped at an ultrahigh pressure into the first-sub chamber, and the pressure in the first sub-chamber causes a second fluid to be processed to be discharged from the second sub-chamber into a processing valve. A system is also provided for performing the steps of this method.

摘要： A pressure intensifier including reciprocating pistons located in respective piston chambers, and a valve mechanism which reciprocates corresponding to movement of the pistons. A pressurized fluid is received by the intensifier and is routed to the piston chambers via movement of the valve mechanism to drive the pistons for boosting pressure of an outgoing fluid. Thus, the pressure of the incoming fluid is used to boost the pressure of the outgoing fluid.

摘要： A system for delivering cryogenic fuels to an engine uses a plurality of cryogenic pumps operating in offset phases to deliver high pressure fuel with a minimum of pressure ripple. The cryogenic pumps use engine oil and a hydraulic pump for actuation via electrohydraulic valves. A charge pump maintains pressure in the feed line so that the cryogenic pumps can be located away from the cryogenic fuel tank. A control strategy for the hydraulic pumps allows output pressure and flow rate to be closely controlled and regulated.

摘要： The present invention is directed to a water pump that may be easily constructed from inexpensive parts and materials and that is powered by the water source from which the water to be pumped is drawn. In a preferred embodiment, two pairs of lever arms located on opposite sides of the pump are alternately filled with water from the source and then emptied causing the lever arms to alternately ascend and descend. As the lever arms ascend and descend, they alternately fill and then compress a pair of pistons causing water to be pumped to an outlet of the pump. Water from the emptied lever arms may preferably be returned to the source, thus minimizing any impact of the pump on the environment and downstream users of the water source.

摘要： A well service pump system supplies high pressure working fluid to a well. The pump system is a linear design which incorporates a diesel engine, a hydraulic drive gear box, open loop hydraulic Pumps, hydraulic ram cylinders, controls for the hydraulic system hydraulic cylinders, working fluid end cylinders and a coupling to connect the hydraulic cylinders and the working fluid ends. The engine powers the hydraulic system which, in turn, provides hydraulic fluid to operate the hydraulic ram cylinders. Each of the polished rods of the hydraulic ram cylinders is connected axially to a plunger rod end of a working fluid end cylinder. There is no crankshaft or automatic transmission required. The linear design allows for a longer plunger stroke length while still allowing highway transport on a truck or skid.
