摘要： A scroll compressor includes a back pressure chamber oil-feeding path for feeding lubricating oil from a high-pressure region to a back pressure chamber, and a compression chamber oil-feeding path for feeding lubricating oil from the back pressure chamber to a compression chamber. One phase in which the back pressure chamber oil-feeding path is communicated from the high-pressure region to the back pressure chamber and another phase in which the compression chamber oil-feeding path is communicated from the back pressure chamber to the compression chamber are shifted from each other, so that the back pressure chamber oil-feeding path and the compression chamber oil-feeding path are never put into the communicating state simultaneously. Thus, after a halt of the compressor, under-communication oil-feeding of the lubricating oil from the high-pressure region via the back pressure chamber to the compression chamber can be prevented, so that the lubricating oil in the liquid storage section is kept from decreasing and moreover the lubricating oil is kept from being filled into the compression chamber, make it possible to achieve a stable restart-up.

摘要： A scroll compressor includes a fixed scroll and an orbiting scroll which define therebetween a plurality of compression chambers for compressing fluid introduced via a suction port. The orbiting scroll has a base plate and a shaft portion extending from the base plate toward a crankshaft rotatably supported by a support member. A seal member is disposed between the base plate and the support member to define an inner region and an outer region. The inner region surrounds the shaft portion, while the outer region includes therein a rotation preventing member interposed between the base plate of the orbiting scroll and the support member. The inner region communicates with the outer region via an oil-feed passage formed through the orbiting scroll. The oil-feed passage includes therein a restrictor and opens in the neighborhood of an upper sliding portion between the rotation preventing member and the support member. Thus, lubricating oil supplied to the inner region is fed to the neighborhood of the upper sliding portion via the oil-feed passage for lubrication thereof. The lubricating oil collects downward due to the gravity to achieve lubrication of a lower sliding portion between the rotation preventing member and the support member.

摘要： A scroll compressor has a check valve assembly for selectively opening and closing a discharge port and allowing a fluid to flow only from the discharge port towards a discharge chamber. A stationary end plate mounted in the scroll compressor has a plurality of bypass holes defined therein at locations symmetrical in terms of pressure. The plurality of bypass holes are open to compression chambers closest to the discharge port and communicate with the discharge chamber. The stationary end plate also has at least one bypass valve for selectively opening and closing the bypass holes and allowing the fluid to flow only from the compression chambers towards the discharge chamber through the bypass holes. The bypass holes are serviceable to prevent an excessive compression and are positioned so as not to be closed by an orbiting scroll wrap immediately after the compression chambers closest to the discharge port have communicated with the discharge port.

摘要： It is an object of the present invention to improve the efficiency of a scroll gas compressor by operating a bypass at a proper compression ratio. To achieve the object, the present invention is constituted so that at least one pair of bypass holes whose one ends are opened in a compression chamber currently performing compression nearby a discharge vent and whose other ends communicate with a discharge chamber are asymmetrically arranged on a panel board. This structure makes it possible to improve the efficiency of the compressor by operating the bypass at an optimum compression ratio even if a difference is observed between pressure rises of a pair of symmetric compressed spaces under the compression process.

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.
