  • Patent number: 5082432
    Abstract: This invention discloses an axial sealing mechanism for axially sealing an orbiting scroll and a fixed scroll of a scroll type compressor. The compressor includes a driving mechanism for driving the orbiting scroll in an orbital motion and a block member fixedly attached to the housing of the scroll compressor to support the driving mechanism. The block member and the fixed scroll define an intermediate chamber in which the orbiting scroll is disposed. The intermediate chamber is divided into a first and second chamber by an end plate of the orbiting scroll. At least one first conduit sized to produce a pressure throttling effect, links the second chamber and the discharge chamber of the compressor to increase the pressure in the intermediate chamber. At least one second conduit, which also is sized to produce a pressure throttling effect, links the second chamber to the suction chamber of the compressor.

  • Patent number: 5000669
    Abstract: 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 bearings in inner blocks. The drive shaft is operatively linked to an orbiting scroll which orbits within a stationary scroll. A rotation prevention device prevents rotation of the orbiting scroll. The drive shaft includes an axial bore extending from an open end and terminating adjacent a forward bearing. A pin extends from the end of the drive shaft to the orbital scroll. A passage links the axial bore to an opening at the end of the pin facing the orbital scroll. Radial bores are provided near the terminal end of the axial bore and at the rearward end of the axial bore near a rearward bearing. The radial bores link the axial bore to a suction chamber of the compressor to allow lubricating oil to lubricate the bearings. The narrow passages allows lubrication of the rotation prevention mechanism.

  • Patent number: 4958991
    Abstract: An oil separating mechanism of a hermetically sealed scroll type compressor in which an inner chamber of a housing is kept at discharge pressure is disclosed. The compressor includes a drive shaft supported by a plain bearing in an inner block member. The drive shaft is operatively linked to an orbiting scroll which orbits within a stationary scroll. The drive shaft includes an axial bore extending from an open and termination within the inner block member. A radial bore is provided near the terminal end of the axial bore and links the axial bore to a discharge chamber of the compressor. A helical groove is formed on the exterior surface of the supported portion of the drive shaft. The helical groove is linked to the axial bore through a radial hole formed through the supported portion of the drive shaft.

  • Patent number: 4940396
    Abstract: 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.

  • Patent number: 4859156
    Abstract: A coupling mechanism for a compressor of an automotive air conditioning system which is provided with a safety mechanism for preventing damage to the engine due to compressor failure. A front end plate with a tubular extension which extends in the direction parallel to the axis of rotation of the drive shaft is attached to one end of the compressor housing. A pulley is rotatably supported on said extension by means of a bearing. At its terminal end, the drive shaft is connected to a plate-like element which includes a centrally located hole through which the drive shaft extends. The plate-like element is connected by means of a bolt and a nut and rotates with the drive shaft. The pulley transmits rotational motion from the engine to the shaft through the plate-like element by means of cylindrical members which are interposed between the pulley and the plate-like element. The cylindrical members are made out of an easily destroyed material.
