摘要： A thrust plate disposed between an orbiting scroll member and a bearing for receiving a force axially exerted thereon is provided with a protrusion formed on the same plane as the thrust plate and projected radially inward. The bearing has a thrust plate holder comprising a recess to which the protrusion of the thrust plate fits in, by which the thrust plate is prevented from rotating while being able to move smoothly in an axial direction. Abrasion caused by rotation of the thrust plate is thus prevented, as well as abrasion on outer circumferential parts of the thrust plate can be prevented as a result of the thrust plate is capable of slightly shifting for adjustment to follow up any precessional movement of a thrust load.

摘要： In a scroll compressor, a stationary scroll is pressed toward a movable scroll by a back pressure of a discharge fluid compressed by a compression mechanism, and wear powder, produced from an annular seal (which receives the pressure of the discharge fluid) as a result of precession of the stationary scroll, is arrested, thereby achieving the scroll compressor high in efficiency and reliability. A pressure-receiving surface for receiving a back pressure of the discharge fluid so as to press the stationary scroll toward the movable scroll is formed on that portion of the stationary scroll disposed around a communication port which is formed in the stationary scroll, and communicates with a discharge port. An annular seal is provided to form a seal between the stationary scroll and an upper frame around a region of communication between the communication port and the discharge port in such a manner as to satisfy a necessary annular sealing surface area, and a circumferential recess is provided on that side lower in pressure than this annular seal.

摘要： A scroll compressor has a compression mechanism accommodated in a closed container and comprising a stationary scroll and an orbiting scroll. The stationary scroll includes a frame and a separate wrap element secured to the frame or otherwise movable relative to the frame. The orbiting scroll has a wrap element allowed to undergo circular translation with respect to the wrap element of the stationary scroll to compress gas. The wrap element of the stationary scroll is made of a readily machinable abrasion-resistant material to reduce the manufacturing cost of the scroll compressor.

摘要： A scroll compressor has a closed vessel, a compression mechanism accommodated in the closed vessel and including a non-orbiting scroll and an orbiting scroll in engagement with each other, and an electric motor for driving the compression mechanism. The non-orbiting scroll includes a frame portion and a non-orbiting end plate axially movable relative to the frame portion. The frame portion has a recess defined therein and a pin secured thereto. The non-orbiting end plate has a cylindrical wall integrally formed therewith and loosely received in the recess, thereby radially positioning the non-orbiting end plate relative to the frame portion. The non-orbiting end plate also has a recess defined therein in which the pin is loosely received, thereby circumferentially positioning the non-orbiting end plate relative to the frame portion. The pin is hardened so as to have a Rockwell hardness of more than 35 on scale C and has a chemical compound layer deposited thereon, to thereby minimize wear thereof.
