A scroll compressor includes a flow path that is disposed in a portion of a bearing holder, which corresponds to each formation position of a plurality of stator groove portions, and that penetrates the bearing holder in an axial direction, a first recess portion (72) disposed in a portion of a thrust bearing, which faces the flow path, and recessed from one side in the axial direction to the other side in the axial direction, and a first groove portion (74) disposed in an outer peripheral portion of the first recess portion (72), extending from a bottom surface (72a) of the recess portion (72) to a surface located on a side opposite to a surface having the first recess portion (72) formed thereon, and communicating with the first recess portion (72) in the axial direction.

The present disclosure provides a compressor and an air conditioner having the same. The compressor includes: a main shaft with a convex portion and a slip sheet; a cylinder; and an air inlet and outlet device including a disk body and an air suction port including an outer side, an inner side and a connecting side located between the outer side and the inner side, wherein the outer side is overlapped with an inner wall of the cylinder or is located on the inner side of the inner wall of the cylinder, the inner side is overlapped with an outer wall of the convex portion or is located on the outer side of the convex portion, and the connecting side is overlapped with a side wall of the slip sheet or is located on the inner side of the side wall of the slip sheet.

To be as lightweight and compact, for example for automotive technology, a scroll compressor further includes an axial guide that supports the movable compressor body to prevent movements in the direction parallel to a centre axis of the stationary compressor body and, in the event of movements, guides it in the direction transverse to the centre axis. A coupling prevents the movable compressor body from rotating freely. The axial guide supports a compressor body base, which carries the scroll vane, of the second compressor body against an axial support face, in that the axial support face abuts a sliding body such that it is slidable transversely to the centre axis. The sliding body is slidable transversely to the centre axis, on a carrier element that is arranged in the compressor housing.

A method for repairing a worn portion in an inner diameter surface of a bore of a cast iron part is disclosed. The inner diameter surface of the bore may have an original surface geometry prior to wear. The method may comprise forming a crescent-shaped pocket in the inner diameter surface of the bore to remove the worn portion, installing an insert in the crescent-shaped pocket, and post-machining the insert to form a crescent-shaped insert that is flush with the original surface geometry of the bore inner surface diameter.

An improved repair method and repair kit for gerotor pumps that have become damaged or worn via insertion of a wear plate to directly contact the gerotor and engine casing in order to allow the pump to create a sound seal once more.

A scroll compressor has a drive shaft which drives a scroll compression mechanism housed in a housing and a drive shaft support member which supports the drive shaft. The drive shaft support member includes a plate portion having a predetermined thickness in an axial direction of the drive shaft. One side end surface of the plate portion has thereon a sliding support surface which supports the sliding movement of an orbiting scroll. Another side end surface of the plate portion has formed thereon a protruding portion which, protruding toward the other side in the axial direction, is fitted onto an inner peripheral surface of the housing. The protruding portion is interference fitted onto the inner peripheral surface of the housing, and thereby the drive shaft support member is fixed to the housing.

A sliding component has an annular shape with a fluid facing inside and outside of the sliding component and has a sliding surface relatively sliding with eccentric rotation, in which the sliding surface includes a land and a plurality of dynamic pressure generation mechanisms arranged in a circumferential direction, the dynamic pressure generation mechanism includes a shallow groove portion and a deep groove portion, the shallow groove portion communicates with the deep groove portion, and a communication passage providing a communication between the deep groove portion and either an inside space or an outside space of the sliding component is formed in the sliding component.

A scroll machine, in particular a scroll compressor, has a first scroll unit with a base and a scroll rib protruding from the base with a scroll rib tip, a second scroll unit with a base and a scroll rib protruding from the base with a scroll rib tip. The first scroll unit can be moved along an orbital path relative to the second scroll unit and the first scroll unit and the second scroll unit engage with each other to form pressure chambers, and the scroll rib of a scroll rib tip having a face seal abuts sealingly to the base of the respective other scroll unit. The base of the first scroll unit and/or the base of the second scroll unit include(s) a pocket with an insert plate arranged in the pocket. Also contemplated is a refrigeration system.

A scroll compressor includes a drive motor, a rotary shaft coupled to the drive motor, a main frame disposed below the drive motor, a fixed scroll disposed below the main frame, an orbiting scroll disposed between the main frame and the fixed scroll and eccentrically coupled to the rotary shaft, and an Oldham's ring coupled to the main frame and the orbiting scroll and configured to restrict rotation of the orbiting scroll relative to the fixed scroll. The Oldham's ring includes: a ring body, a first key that receives a first fixing boss of the ring body and that is configured to couple to the main frame, and a second key that receives a second fixing boss of the ring body and that is configured to couple to the orbiting scroll.

A scroll compressor includes a first scroll and a second scroll engaged with the first scroll to form a compression chamber with the first scroll while performing an orbiting movement with respect to the first scroll. A frame is fixed to a side of the first scroll with the second scroll interposed between the frame and the first scroll and the frame supporting the second scroll in an axial direction. An Oldham ring includes a ring portion and a key portion protruding from the ring portion. The key portion is slidably coupled to a key recess in the frame or the second scroll to enable the second scroll to perform the orbiting movement, and the key portion of the Oldham ring is formed of the same material as the second scroll. A wear preventing member is provided between the key portion and the key recess.
