摘要： A compressor including: a casing; a rotary shaft rotatably mounted in the casing; a compression mechanism configured to compress a refrigerant by operating in conjunction with the rotary shaft; a thrust plate configured to support an end surface of the rotary shaft; a chamber configured to accommodate the thrust plate; and a slit configured to guide oil to the chamber, in which a part of the slit is formed to face a contact portion between the rotary shaft and the thrust plate, such that it is possible to supply the oil between the rotary shaft and the thrust plate, thereby preventing damage to the thrust plate for supporting the rotary shaft. In addition, an inner diameter of the chamber gradually increases, and the chamber extends to an end surface of a cylinder block, such that the cylinder block may be easily extracted from a mold.

摘要： The present invention provides a piston type compressor and a high-pressure gas station having the compressor. The compressor includes a piston that divides a cylinder into a compression chamber and an intake chamber, and a check valve is installed in a bearing wall thereof, so that the output pressure is allowed to be compressed to a high pressure even when the intake pressure significantly decreases.

摘要： A 3D-printed oil separation assembly for use in a reciprocating compressor is provided. The compressor includes a suction chamber, a crankcase chamber, and at least one partition member at least partially separating the suction chamber and the crankcase chamber. The at least one partition member further includes at least one opening. The 3D-printed oil separation assembly comprises a coalescing structure positioned within the crankcase chamber adjacent the at least one partition member at the at least one opening; and at least one securing structure secured in operable relation with the at least one demisting structure so as to secure the coalescing structure relative to the opening. The coalescing structure comprises at least one structure selected from the group consisting of a baffled structure, a demisting structure, and combinations thereof. At least a portion of the coalescing structure is 3D-printed.

摘要： A pump includes a cam plate, and an input shaft for rotationally driving the cam plate. A pump housing at least partially surrounds the cam plate and defines a cam plate oil reservoir around at least a portion of the cam plate. A bearing support is at least partially disposed within the cam plate oil reservoir. The bearing support defines a bearing oil reservoir at least partially surrounding a portion of the input shaft. At least one passage extends between the bearing oil reservoir and the cam plate oil reservoir. Dynamic motion imparted on oil within the cam plate oil reservoir facilitates migration of oil from the cam plate oil reservoir through a bearing at least partially supported by the bearing support into the bearing oil reservoir and through the at least one passage into the cam plate oil reservoir.

摘要： A piston type compressor has a main housing including a cylinder housing. The cylinder housing has a central bore for receiving a shaft therein through a first surface thereof and a plurality of bores configured for receiving a plurality of pistons therein through the first surface thereof. An inlet is configured for conveying a primary fluid to the plurality of bores. An outlet is configured for conveying the primary fluid from the plurality of bores. A plurality of passages is separate from the inlet and the outlet. Each of the plurality of passages is formed in the main housing and is configured for conveying a supplemental fluid to one of the plurality of bores.

摘要： The carbon free compressor pump system is a device that utilizes several pistons in a hydraulic or power press manner to compress gas or pump fluids. The device utilizes mechanical advantage of a pulley on the upstroke and uses a clutch device to utilize the gravitational force on the downstroke. In order to accomplish this the device includes a base that allows the compression process to take place and ensure there is only vertical movement. Further, the weight block ensures the system can utilize gravitational force on the downstroke. Further, the plurality of outtakes allows for the gas or fluids to flow out of the system once compressed or pumped. Furthermore, the conical tank takes the compressed gas or pumped fluid and further compresses the gas, increasing the pressure without moving parts. Thus, the device operates on carbon free electricity to compress gas and pump fluids.
