    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.

    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 sealed compressor has a sealed casing in which a motor section and a compression section are both accommodated, and also has a pipe connector including at least one sleeve. The sleeve has a first end and a second end opposite to each other. The first end is inserted into a sleeve insertion hole defined in the compression section to allow a refrigerant to flow therethrough, while the second end is hermetically brazed to a copper pipe disposed outside the sealed casing. The sleeve is formed by deep-drawing a copper-plated steel plate into a generally cylindrical shape.

    摘要： A scroll compressor includes a scroll assembly accommodated in a closed container, a crankshaft for driving the scroll assembly, a main bearing for rotatably supporting one end of the crankshaft, and an auxiliary bearing for rotatably supporting the other end of the crankshaft. A recess is defined between the internal surface of the closed container and the external surface of a compression section comprised of the scroll assembly and the main bearing. A portion of a jig is inserted into the recess to achieve concentricity and parallelism of the auxiliary bearing with respect to the main bearing using reference planes defined in the auxiliary bearing and the compression section or by radially adjusting the auxiliary bearing.
