摘要： The purpose of the present invention is to provide a multi-cylinder compressor permitting to increase a gas inflow into the housing without enlarging the intake ports of the bearing plate. The bearing plate 12 bearing the crankshaft 9 is provided with plural intake ports 12a at regular intervals in the circumferential direction. The substantially inversely-dished cover member 14 is mounted on the top of the bearing plate 12, and it not only covers the plural intake ports 12a, but also forms a sealed space S between the cover member and the bearing plate 12, and is further provided with an introducing opening 14a larger than the intake port 12a at the center top of the cover member 14. The introducing opening 14a is fitted with the gas supply pipe 15 to be connected to the gas supply source (not illustrated).

摘要： A pump for providing a pressurized fluid flow. The pump includes a pump casing that defines a pump chamber. A pump shaft is has a head end in the pump chamber; the head end has a circumferential outer surface. The pump shaft head end has inwardly extending piston chambers. A discharge manifold is formed in the pump shaft head end. The discharge manifold has one end in fluid communication with the piston chambers and a second end in fluid communication with a discharge conduit that extends outside of the pump casing. A piston is mounted in each piston chamber. The pistons are formed with flow-through bores that provide fluid communication between the pump chamber and the piston chambers. A suction valve associated with each piston regulates fluid flow from the pump chamber through the flow-through bore into the associated piston chamber. Discharge valves regulate fluid flow from each piston chamber into the discharge manifold. The head end of the pump shaft is axially offset from the center axis of the pump chamber. As the pump shaft is rotated, the pistons engage in reciprocal motion in their piston chambers. Fluid is introduced into the pump chamber. When each piston is in its extended position, the suction valve allows fluid flow into the piston chamber. When each piston is retracted, it forces the fluid in the associated piston chamber through the discharge valve, through the discharge manifold and out the discharge conduit.

摘要： One or more examples of the gas boosters described herein aim to provide a light weight gas booster configured to produce high output pressure levels at high volumes. Generally described, one or more examples of the gas boosters reduce the dead volume in a piston assembly, thereby increasing the ratio of the output pressure to the input pressure. In that regard, several examples of the gas boosters disclosed herein have a first check valve as a disk-type check valve or the like and a second check valve as a ball-type check valve or the like. Furthermore, one or more examples include an inwardly acting cam configured to convert rotary motion to reciprocating motion by an inner surface thereof.

摘要： A Positive Fluid Displacement Device (PFDD) with a removable Fluid Displacement Module (FDM) having two opposing pistons connected to a drive block. The drive block slides over a crankpin bearing in assembly to provide orbital piston motion. Opposing cylinders are held within a carriage for reciprocating motion. An opening in the reciprocating cylinder head allows fluid communication to the displacement chamber through inlet and outlet ports in a floating port plate. The flat surfaces of the port plate and cylinder head wipe across each other during cylinder head movement. The piston head carries a protrusion sized to fill the cylinder head opening. Micro-adjustment mechanisms for the position of the cylinder head together with compliant piston and compliant cylinder mechanisms can provide near zero dead volume. Different sized opposing cylinders enable the delivery of pumped fluids in precise ratios. By connecting the outlet of each cylinder to the inlet of the opposing cylinder, the differential displacement of the two cylinders can be pumped, enabling the delivery of very small quantities of fluid. High vacuum may be delivered by series connection of cylinders. The device may incorporate a dual lip piston seal which is wear compensated over the life of the seal. The PFDD is leakage free and can be driven by stepper motors to deliver a precise fluid amount at low speed even to an exact portion of a piston stroke. A sensor is provided for sensing cylinder head position.
