摘要： A scroll compressor is provided that may include a casing, a drive motor, an orbiting scroll, a non-orbiting scroll, and a floating plate provided with a cover portion to cover an area between an outer wall portion and an inner wall portion of the non-orbiting scroll so as to form a back pressure chamber with the non-orbiting scroll, and a valve accommodating portion that extends from the cover portion so as to accommodate a discharge valve configured to open and close a discharge port. Accordingly, structure for forming a back pressure chamber is simplified to thereby reduce the number of components and man-hours required for assembly.

摘要： A pin-ring mechanism that transmits driving force to cause a driving-side scroll member and a driven-side scroll member to perform rotational movement in a same direction at a same angular velocity is provided. A driving-side end plate includes a ring member installation hole into which a ring member is inserted and installed. The ring member installation hole includes a non-wall-side hole part and a wall-side hole part. The non-wall-side hole part is formed from a non-wall-side surface and has a diameter corresponding to an outer diameter of the ring member. The wall-side hole part is formed from a wall-side surface and has a diameter smaller than the outer diameter of the ring member.

摘要： A scroll compressor includes a movable scroll having first key grooves, a stationary member having second key grooves, and an Oldham coupling provided between the movable scroll and stationary member. The Oldham coupling is movable with respect to the stationary member along a first axis, and with respect to the movable scroll along a second axis. The Oldham coupling has an annular body portion, at least two first key portions fitted into the first grooves, and a pair of second key portions fitted into the second grooves. The first horizontal surface has inwardly positioned surfaces positioned more on a center of gravity side of the Oldham coupling than virtual extension lines of first inner peripheral edges that are part of an inner peripheral edge of the annular body portion. The first key portions have inwardly positioned portions that project from the inwardly positioned surfaces.

摘要： Oldham couplings are disclosed, for example, for use in electric camshaft adjusters. The Oldham coupling may include a first outer connecting disk and a second outer connecting disk having axes of rotation extending parallel to each other and a central connecting disk including one or more through-bores. One or more connecting elements may couple the first outer connecting disk to the central connecting disk via the through-bore(s). A sleeve may be arranged in the through-bore(s) such that the connecting element(s) contacts the sleeve and wear of the central connecting disk is reduced. For example, the sleeve may prevent direct contact of the connecting element(s) with the central connecting disk, such as by a spacer or flange. The sleeve may be made of metal, while the central connecting disk may be plastic or metal.

摘要： A scroll compressor includes a scroll compression unit having a fixed scroll and an orbiting scroll a drive shaft configured to drive the orbiting scroll in an orbital movement, and a support frame including a bearing configured to guide in rotation a guided portion of the drive shaft. The scroll compressor also includes an anti-rotation device including a pair of first engaging elements slidably engaged with a pair of complementary engaging elements on the support frame; and a lubrication system to lubricate at least partially the first engaging elements. The lubrication system includes a lubrication channel and hole on the drive shaft; the hole is fluidly connected to the channel and emerges in an outer wall of the guided portion. The system further includes an oil lubrication passage on the support frame, which includes an oil inlet aperture emerging in a receiving chamber, and an oil outlet aperture configured to supply with oil at least one of the first engaging elements.
