摘要： The invention relates to a fuel pumping device for two-cycle engines with at least a one-piece housing, on which a pulse air connector (14), which is pneumatically connected with the crankcase of the two-cycle engine, a fuel aspiration connector and a fuel pressure connector are arranged, in which a diaphragm (41) on which pulse air acts, drives a pump piston (22) in connection with a diaphragm disk (42), in the course of which fuel being supplied from the tank (1) at the fuel aspiration connector during the pump aspiration stroke is aspirated via a flap valve (61) into the compression chamber (51) located upstream of the pump piston, and is pumped during the compression stroke via a further flap valve (71) into the fuel pressure connector and into a reservoir (73) and/or an injection valve (5). The pulse air connector (14) terminates in a housing chamber (13) located between the diaphragm (41) and the pump piston (22), and at least one spring element (15, 35, 94) acts on each side of the diaphragm (41). Here, the spring element (15) arranged in the housing chamber (13) is supported on the diaphragm (41) via the separate pump piston (22). An electromagnetic drive unit (90) is arranged in the housing chamber (33) located on the other side of the diaphragm (41), which via its armature (91) supports the compression stroke of the pump piston (22) synchronously with the compression stroke of the two-cycle engine.

摘要： A compact transportable compressed-air piston engine for paint-spraying devices, dosing pumps, grease guns or the like, makes it possible, without much effort, to carry out various length working strokes of a working piston. A compact engine is obtained by mounting the control in/on the cylinder head or in/on the cylinder bottom with axes extending transversely with respect to a main axis so that stroke changes can be achieved solely by the working piston contacting the valve piston rods of switch valves. In addition, return springs are not needed in the switch valves, which are required for reversing and are operated by the working piston.

摘要： A metering device for the precision feeding of a liquid, such as, for example, an oil lubricant. The device has a fluid supply chamber with a working medium such as oil and which in turn is in open communication with a metering chamber also containing the medium fluid. A fluid pumping piston passes through the supply chamber and then into the metering chamber. Upon entering the metering chamber, the pumping piston passes through an annular flexible seal of generally U-shaped cross section that has a pair of axially extending lips which act, respectively, along the piston and the metering chamber to thereby form a one-way valve therebetween. The piston forces the fluid out of the metering chamber and the volume displaced by the piston can be adjusted by adjusting the axial position of the metering chamber and thereby vary the extent to which the pumping piston enters the metering chamber.

摘要： A low pressure compressor drives a hydraulic pump coupled to a main compressor for producing a relatively high pressure gas output. A plurality of pistons coupled to a single shaft is driven by gas from a low pressure compressor. A hydraulic piston is coupled to one end of the shaft and forces hydraulic fluid from a hydraulic cylinder into a main compressor having a main hydraulic cylinder and a free main piston. The free main piston is forced to one end of a main air or gas cylinder. Passages from the main air or gas cylinder direct the high pressure air or gas to a gas or air storage tank. The high pressure gas contained within the storage tank is then released when needed. A series of valves control the direction and pressure of the gas or air and hydraulic fluid. The present invention makes possible the production of relatively high gas pressures. Additionally, the present invention remains relatively cool during operation.

摘要： A pilot control relay valve to change the directional flow of fluid to a piston (such as, for example, the piston of a chemical injection pump for injecting chemicals at a slow or rapid rate over a long period of time), but also allow the recovery of exhaust fluids under significant back pressure. The pilot control relay valve comprises an elongated valve member shiftable within a valve body between a first and second position. The first position allows communication of control fluid to a first pressure receiving surface while allowing exhausting of fluid from a third or opposing pressure receiving surface, thereby to initiate movement of the valve member against the back pressure of the exhaust fluid from its first position to a position equalizing the pressure acting on a second pressure receiving surface with the pressure of the control fluid, thereby causing the valve member to move to its second position. The valve member when it is in its second position allows communication with the third pressure receiving surface while allowing exhausting of fluid from the first pressure receiving surface for initially moving the valve member against the back pressure of the exhaust fluid from its second position while equalizing the pressure acting on the second pressure receiving surface to move the valve member to a position equalizing the pressure acting on the second pressure receiving surface with a pressure lower than the pressure of the control fluid for moving the valve member from its first position, whereby the operation is repeated ad infinitum. Piping is connected to threaded exhaust ports in the valve body to communicate exhaust fluid to a reservoir where it is collected under pressure for further use.

摘要： A downhole pump comprises a pump cylinder driven by a pneumatic cylinder. A compressor compresses air and delivers compressed air to the pneumatic cylinder under the control of first and second trip valves and a pilot valve. The trip valves control the pilot valve so that it alternately delivers the compressed air above and below the pneumatic cylinder piston to reciprocally drive the piston. The pneumatic cylinder piston connects to the pump cylinder via a pair of push rods to drive the pump cylinder piston to pump water from the well to an above-ground reservoir.
