    • A motor driven fluid compressor having compression and drive mechanisms within a hermetically sealed housing is disclosed. The compressor includes the compression mechanism, and the drive mechanism. A drive shaft and a motor rotates the drive shaft. A hermetically sealed housing contains the compression mechanism and the drive mechanism. The drive shaft is operatively connected to the compression mechanism, and is rotatably supported by a first inner block and a second inner block which is axially spaced from the first inner block. The first and second inner blocks are integral with first and second portions of the housing, respectively. As a result, the longitudinal axis of holes formed within the first and second inner blocks and the longitudinal axis of the compressor housing are easily and precisely aligned without increasing in the manufacturing cost.

    • The present invention discloses an orbiting member fluid displacement apparatus including a rotation preventing and thrust bearing device. The rotation preventing and thrust bearing device includes a fixed portion, an orbital portion, and bearing elements. The fixed portion includes a first annular race and a first ring, which are formed separately. The first annular race is placed in a loose fit within a first annular step in an inner surface of the housing and the first ring is attached to the housing. The orbital portion includes a second annular race and a second ring, which also are formed separately. The second annular race is placed in a loose fit within a second annular step in an end plate of the orbiting member and the second ring is attached to the end plate of the orbiting member. A plurality of pockets are formed in the rings and face one another in substantially aligned pairs. A bearing element is received in each aligned pair of pockets to prevent the rotation of the orbiting member by the bearing elements interacting with the first and second rings and to bear the axial thrust load from the orbiting member. One or more lubricant conductive grooves are formed at first contacting surfaces between the first annular race and the housing or second contacting surfaces between the second annular race and the orbiting member, or both.
    • 本发明公开了一种包括旋转防止推力轴承装置的轨道构件流体位移装置。 旋转防止推力轴承装置包括固定部分,轨道部分和轴承元件。 固定部分包括单独形成的第一环形圈和第一环。 第一环形圈在壳体的内表面内的第一环形台阶内以松配合的方式放置,第一环附接到壳体。 轨道部分包括第二环形圈和第二环,其也分开形成。 第二环形圈在松动配合中放置在轨道构件的端板内的第二环形台阶内,第二环安装在轨道构件的端板上。 多个凹穴形成在环中并且基本对准成对地彼此面对。 轴承元件被容纳在每个对齐的一对凹穴中,以防止由与第一和第二环相互作用的轴承元件使旋转构件旋转并承受来自轨道构件的轴向推力载荷。 一个或多个润滑剂导电槽形成在第一环形座圈和壳体之间的第一接触表面处或第二环形座圈和轨道构件之间的第二接触表面,或两者之间。

    • A scroll-type fluid displacement apparatus includes a compressor housing, which contains a compression mechanism and a driving mechanism operatively connected to one another. The compression mechanism includes a fixed scroll and an orbiting scroll interfitting at angular and radial offsets, and a rotation preventing mechanism which prevents rotation of the orbiting scroll during its orbital motion. The driving mechanism includes a drive shaft axially disposed within the housing and rotatably supported by an inner block, which is fixedly disposed within the housing. An axial movement regulating mechanism for regulating an axial movement of the driving mechanism is disposed between the inner block and an internal component of the compressor axially spaced from the inner block. The regulating mechanism includes an annular flange extending from an exterior surface of the drive shaft and a shim which is detachably disposed either between the annular flange and the inner block or between the annular flange and the internal component.
