摘要： A hermetic type scroll compressor includes a hermetically sealed compressor housing formed by first and second cup shaped casings. The first casing houses a compression mechanism, while the second casing houses a drive mechanism. The compression mechanism includes a fixed scroll affixed to the first cup shaped casing, an orbiting scroll interfitted at an angular and radial offset with the fixed scroll, and a rotation preventing device disposed between the orbiting scroll and the center block. The movement of both the compression and driving mechanisms may be inspected or tested and those mechanisms may be readily disassembled so that component parts thereof may be adjusted or replaced before hermetically securing the first casing to the second casing. Furthermore, each casing is provided with a center block forming, in part, an alignment mechanism for aligning the drive mechanism drive shaft with the orbiting scroll of the compression mechanism.

摘要： A scroll-type fluid displacement apparatus with a lubricating mechanism to lubricate between an end plate and an opposed spiral wrap is disclosed. The apparatus has a pair of scrolls, each of which comprises a circular end plate and a spiral wrap extending from one side of the end plate. A groove, in which a seal element is loosely fitted, is formed on the axial end surface of each spiral wrap. One spiral wrap has a second groove at its axial end surface and extends close to the outer terminal end of spiral wrap. The sectional shape of the second groove is different from the sectional shape of the first groove to prevent the movement of the seal element in the first groove. Gas containing lubricating oil is supplied to the outer terminal portion of spiral wrap through the first groove and second grooves.

摘要： A lubricating mechanism for a scroll-type fluid displacement apparatus is disclosed. A driving mechanism for an orbiting scroll comprises a drive shaft and a drive pin projecting at an eccentric location from an inner end surface of the drive shaft. An annular boss projecting from a circular end plate of the orbiting scroll receives the drive pin. Therefore, the orbiting scroll is rotatably supported on the drive pin. The lubricating mechanism includes an oil passageway formed in the circular end plate of the orbiting scroll to communicate between the interior of the boss and one of the fluid packets located at the outer peripheral portion of the spiral elements. Lubricating oil thus flows into the interior of the boss and lubricates the bearing and other contact surface disposed in the center portion of the apparatus.

摘要： In a reciprocating compressor in which a suction chamber (7) extends around a discharge chamber (6) parallel to suction, a discharge gas conducting passage (6c) is connected to the discharge chamber and is adjacent to a suction gas inlet passage (7a) in a predetermined direction orthogonal to the plane. The suction gas inlet passage communicates with each of the first and second opposite ends of the suction chamber so that gas is supplied into the suction chamber through each of the first and second opposite ends thereof. A plurality of compression elements are arranged along the suction chamber and connected to the discharge chamber and the suction chamber. Each of the compression elements have a piston (16) which reciprocates to introduce the gas from the suction chamber, to compress the gas, and then to discharge the gas into the discharge chamber.

摘要： A sealing mechanism for sealing an aperture formed through a housing of a closed vessel is disclosed. The sealing mechanism includes a bolt having a threaded shaft portion and a flange portion. A seating portion is formed on the outer opening of the aperture and a rotation preventing portion is formed on the surface of the seating portion. A washer is disposed on the seating portion. The washer is made of a metal softer than the material of the housing. When the bolt is rotated the washer contacts the flange portion of the bolt. The axial force of the bolt causes the washer to engage the rotation preventing portion. The rotation preventing portion deforms the washer and prevents the washer from rotating. Therefore, the inner end surface of the washer does not rub against the surface of the seating portion. As a result, adequate sealing is maintained.

摘要： This invention discloses a lubricating mechanism of a hermetically sealed scroll type compressor in which an inner chamber of a housing is kept at suction pressure. The compressor includes a drive shaft supported by a first plain bearing in an inner block member. The drive shaft is operatively linked to an orbiting scroll which orbits within a stationary scroll. A rotation preventing device prevents rotation of the orbiting scroll. The drive shaft includes an axial bore extending from an open end and terminating within the inner block member. A pin extends from the end of the drive shaft to the orbital scroll and is supported in a bushing within an extension of the orbiting scroll. A second plain bearing supports the bushing. A passage links the axial bore to an opening at the end of the pin facing the orbital scroll. A radial bore is provided near the terminal end of the axial bore to link the axial bore to a suction chamber of the compressor. A first helical groove is formed in the exterior surface of the supported portion of the drive shaft. The first helical groove is linked to the axial bore through a radial hole formed through the supported portion of the drive shaft. A second helical groove is formed in the exterior surface of the bushing. Fluid flows through the radial bore and through the narrow passage to lubricate the rotation preventing device. Fluid flows through the first helical groove to lubricate the friction surface between the drive shaft and the first plain bearing. Fluid flow through the second helical groove to lubricate the surface between the bushing and the second plain bearing.
