20090110585 | REFRIGERANT COMPRESSOR ARRANGEMENT - The invention concerns a refrigerant compressor arrangement with a compressor unit ( | 04-30-2009 |
20090110586 | Refrigerant compressor - A hermetically encapsulated refrigerant compressor which comprises a hermetically sealed compressor housing ( | 04-30-2009 |
20090136375 | REFRIGERANT COMPRESSOR, COOLING SYSTEM AND REFRIGERATOR - A refrigerant compressor having a compression element comprising sliding components made of metallic materials, wherein a mixed layer is formed by solid-dissolving molybdenum disulfide in at least one of the sliding faces of the sliding components, and a single molybdenum disulfide layer is further formed on the surface of the mixed layer. With this configuration, initial break-in is done using the single layer, and sliding loss is reduced. Even if the single layer peels off, because the molybdenum disulfide of the mixed layer is cleaved at a low friction coefficient, solid lubrication action is attained, the friction coefficient of the sliding section is lowered, and sliding loss is reduced. | 05-28-2009 |
20090136376 | HERMETIC COMPRESSOR AND REFRIGERATION SYSTEM - As an refrigerating machine oil ( | 05-28-2009 |
20090155114 | COMPRESSOR STRUCTURE FOR A REFRIGERATION SYSTEM - A compressor structure for a refrigeration system and a component for a refrigeration system. The compressor structure comprises a compression cylinder; a suction line leading gas to be compressed towards the cylinder; and a discharge line leading the compressed gas away from the cylinder; wherein at least one component of the suction line, the discharge line, or both comprises a thermal barrier layer on a surface of the at least one component. | 06-18-2009 |
20090238709 | Magnetic vane ejection for a rotary vane air motor - A magnetic rotary vane pump is disclosed which includes a rotor disposed within a casing that comprises a cavity having an inlet and an outlet. The rotor includes at least one radial slot and at least one vane carried by the radial slot. The vane includes an inner edge directed towards a central axis of the rotor and an outer edge directed towards the casing. The inner edge of the vane is connected to a first magnet. The slot in the rotor includes an inner wall that abuttingly engages or faces the inner edge of the vane when the vane is fully received within the slot. The inner wall of the slot is connected to a second magnet. The two magnets are arranged so that like pole of the magnets face each other thereby biasing the vane out of the slot and against the inner wall of the casing as the rotor rotates. Accordingly, no spring or pin is required to bias the vane outward against the casing or into recesses or slots disposed in the casing wall. The resulting design may be operated faster than conventional vane pumps and with less lubrication or no lubrication than conventional vane pumps. | 09-24-2009 |
20120189482 | COMPRESSOR AND MANUFACTURING METHOD THEREOF - The compressor includes a first constituent element and a first slider. The first constituent element is capable of being laser welded. The first slider is composed of cast iron capable of being laser welded and having a carbon content of from 2.0 wt % or more to 2.7 wt % or less. This first slider is joined to the first constituent element by laser welding without using a filler. | 07-26-2012 |
20130089454 | COMPONENT HAVING REDUCED METAL ADHESION - The invention relates to an assembly ( | 04-11-2013 |
20140255237 | VANE PUMP - A vane pump is provided that may include a rotor having a plurality of slots formed on an outer circumferential surface thereof; a vane slidably inserted into each of the plurality of slots; and a cam ring configured to receive the rotor therein and having a inner circumferential surface in contact with an end portion of the vane. The rotor may be formed of nodular graphite cast iron, the vane may be formed of high speed tool steel, and the cam ring may be formed of alloy cast iron. | 09-11-2014 |
20140255238 | ROTOR OF VANE PUMP AND METHOD OF MANUFACTURING ROTOR - A rotor of a vane pump and a method of manufacturing a rotor are provided. The rotor may be formed to include a plurality of radially formed slots and having a disk shape, and may include approximately 20% to 70% of pig iron, approximately 0.2% to 0.5% of copper (Cu), and approximately 0.1% to 0.4% of iron (Fe) by weight ratio, and scraps and steel wastes for the remainder, and may be formed of a nodular graphite cast iron including precipitated spheroidal graphite and having an austenite structure. | 09-11-2014 |
20140322058 | SCREW COMPRESSOR - In order to prevent deterioration in performance of an oil-free screw compressor and scuffing caused by rust, surfaces of both male and female rotors are coated with heat-resistance coatings containing a solid lubricant. A coating contains Polyimide resin to which Molybdenum disulfide, as a solid lubricant, and Aluminium oxide and Titanium oxide, as additives, are added. Accordingly, it is possible to realize a coating that is higher in heat resistance and longer in lifetime than a conventional one. | 10-30-2014 |
20150098853 | SCREW-TYPE POSITIVE DISPLACEMENT MACHINE - A screw-type positive displacement machine includes a housing with a first rotor and a second rotor which are mounted to rotate in the housing and which are driven in directions which are the opposite of one another. The positive displacement machine has a first motor and a second motor arranged in a drive casing and connected to the housing in such a way that the first rotor is driven by the first motor and the second rotor is driven by the second motor. Typically, the first motor and/or the second motor is an asynchronous motor. | 04-09-2015 |
