摘要： An internal combustion engine in combination with a rotary positive displacement fluid machine. The combination having a rotor eccentrically mounted in a casing with a plurality of vanes defining compartments within the casing which vary in volume as the rotor rotates. Each vane is connected to a linkage to cause the vane, during rotation of the rotor, to pivot radially outwardly such that the outermost extremity of each vane is constrained to follow closely the internal wall of the casing. The linkage being constrained to follow at least one track in a member rotatable upon the same axis as the casing. The machine being connected to an air inlet manifold of the engine, and to atmosphere, such that the rotor is driven by the pressure difference between ambient air and air at the inlet manifold. The machine also is operatively connected to an energy using device.

摘要： The invention relates to the machine building industry and can be used for reverse-running pulsation-free high-pressure pumps. The aim of the invention is to improve the operating characteristics of pumps of a similar variety (and the manufacturability thereof). The inventive pump comprises a rotor with orifices and at least two displacers arranged therein, a working chamber, a barrier separating the increasing area from the decreasing area. The working chamber is formed by surfaces of an annular groove embodied in the end of the rotor in such a way that the inner surfaces thereof confine the working chamber in a radial direction and slide into contact with the barrier's surfaces. The orifices of the rotor containing the displacers are oriented in an axial direction and open out onto the annular groove in such a way that the continuations thereof form pockets on the inner surfaces of the groove, thereby confining the working area in the radial direction.

摘要： A dual chamber or double sided rotary pump includes a stator housing and a rotor. The stator housing has an oblong inner surface. The rotor, which is disposed in the stator housing, has a substantially circular outer surface within which a plurality of vane slots are defined. A first chamber is defined between a first half of the oblong inner surface and the outer surface of the rotor. Similarly, a second chamber is defined between a second half of the oblong inner surface, diametrically opposite the first half, and the outer surface of the rotor. Resting within each of the plurality of vane slots is a corresponding sliding vane. A first inlet port and a first outlet port each provide access to the first chamber. Similarly, a second inlet port and a second outlet port each provide access to the second chamber. At least one of the vanes separates each of the first inlet port, the first outlet port, the second inlet port and the second outlet port from one another.

摘要： A compressor includes a cylinder assembly which is positioned inside a hermetic vessel having a suction flow path and discharging flow path, a Z-plate for dividing an inner space into a plurality of compression spaces in the cylinder assembly, rotating by a motor part so that gas is sucked, compressed and discharged, and a vane for dividing the respective compression spaces into a suction region and compression region, performing a reciprocating movement being contacted on both surfaces of the Z-plate. In addition, an oil slot for inflowing oil into the cylinder assembly is formed on a side surface of the vane. Therefore, friction generated at a sliding portion inside of the cylinder assembly can be reduced and performance deterioration of the compressor caused by operation noise and friction resistance of the compressor can be prevented.

摘要： To provide a gas compressor which is small-sized and suitable for achieving an improvement in terms of cooling capacity. There is formed in the inner surface of a front head a passage-like hollow portion branching off from a suction port of the front head and extending toward two side block suction holes, and a suction passage is formed for each side block suction hole by the passage-like hollow portion in the inner surface of the front head and an outer surface of a side block. A Low-pressure refrigerant gas compressed in a cylinder is conveyed from the suction port of the front head through the bifurcated suction passages to be sucked into the cylinder through the side block suction holes.

摘要： A well production apparatus includes a down-hole gear pump and a transport assembly to which the gear pump is attached. The transport assembly is formed from a string of modular pipe assemblies having one or more passages for carrying production fluid from the bottom of the well to the surface. The passages can be arranged in a side-by-side configuration, and include pressure and return lines for driving the gear pump. The gear pump includes a hydraulically driven motor that is ganged with a positive displacement gear set. Both the motor and the pumping section have ceramic wear surfaces, the ceramic being chosen to have coefficients of thermal expansion corresponding to the coefficients of thermal expansion of the gear sets. The pumps and rotors have ceramic bushings rather than ball or journal bearings, and are operable under abrasive conditions.

摘要： A scroll compressor has a fixed scroll member, a movable scroll member, a housing. The housing is secured to the fixed scroll member. The housing accommodates the movable scroll member to define a back pressure chamber. Pressure in the back pressure chamber is applied to the back surface of a movable scroll base plate of the movable scroll member. The back pressure chamber communicates with a region through a communication passage. The region is lower in pressure than the back pressure chamber. The communication passage relieves the pressure in the back pressure chamber to the region. The communication passage includes a valve. The valve varies an opening amount of the communication passage due to difference between the pressure in the compression region in the predetermined period of a compression process of the gas, and the pressure in the back pressure chamber.
