摘要： In some examples, a co-rotating scroll compressor includes a driver scroll having an axis aligned with the main axis and having a spiral involute, an idler scroll having an axis offset from the main axis and having a spiral involute intermeshed with the spiral involute of the driver scroll, and an Oldham coupling disposed between the driver scroll and idler scroll. The driver scroll may offset key slots so to engage with corresponding Oldham coupling keys. In another example, the Oldham coupling may offset driver scroll keys so to engage with corresponding key slots of the driver scroll.

摘要： Provided are a fluid circulation system and a method for operating same, a computer-readable medium, and a controller. The fluid circulation system comprises: a scroll expander, and an external fluid circulation path, which comprises a high-pressure fluid pipe and a low-pressure fluid pipe. The operation method comprises the following steps: before fluid is supplied to the scroll expander, making the fluid pressure in the high-pressure fluid pipe higher than the fluid pressure in the low-pressure fluid pipe by a pre-determined pressure difference; and after the pre-determined pressure difference is realized, starting the scroll expander and supplying fluid to the scroll expander. According to the present disclosure, the technical problem of a scroll expander being unable to be normally started and work can be avoided, and the invention is simple, practical, convenient, and easily implemented.

摘要： A scroll device has a fixed scroll, and orbiting scroll, and at least one cooling chamber configured to receive coolant to cool the fixed scroll or the orbiting scroll. A flexible conduit that curves around an orbital axis of the orbiting scroll may transfer coolant into or out of the at least one cooling chamber. The scroll device may have a motor with a motor jacket configured to receive coolant for cooling the motor. One or more involutes of the scroll device may comprise a wall coated or plated with a solid abrasion-resistant lubricant.

摘要： Disclosed is a scroll compressor including stationary and movable scroll members engaged with each other. The stationary scroll member defines first and second air inlets and first and second air outlets. A first compression path is formed between the first air inlet outlet, and a second compression path is formed between the second air inlet outlet. The scroll compressor further includes a bypass passage for selectively communicating at least one of the first and second compression paths with a suction pressure area of the compressor. First and second back pressure cavities are formed on a side of the stationary scroll member facing away from the movable scroll member. The first back pressure cavity is in communication with the first compression path by means of a first back pressure passage. The second back pressure cavity is in communication with the second compression path by means of a second back pressure passage.

摘要： Provided is an efficient scroll compressor capable of suppressing deformation of a fixed scroll during operation. The scroll compressor includes: a fixed scroll (30) including a fixed-side end plate (32) and a spiral fixed-side wrap (34) protruding from a front surface (32a) of the fixed-side end plate; a movable scroll (40) including a spiral movable-side wrap (44) combined with the fixed-side wrap to form a compression chamber (Sc); and a cover member (60) disposed in a high-pressure space on a rear surface (32b) side of the fixed-side end plate and attached to the fixed scroll. The fixed-side end plate includes a compression chamber adjacent portion (33) at which the front surface of the fixed-side end plate faces the compression chamber. The compression chamber adjacent portion includes a high-pressure adjacent portion (33a) disposed at a central portion of the compression chamber adjacent portion, and an intermediate- and low-pressure adjacent portion (33b). At the high-pressure adjacent portion, the front surface of the fixed-side end plate faces a high-pressure compression chamber. The intermediate- and low-pressure adjacent portion is disposed on the outer side of the high-pressure adjacent portion. The cover member defines a low- or intermediate-pressure rear surface adjacent space (S3) that faces at least a part of a rear surface of the intermediate- and low-pressure adjacent portion in the compression chamber adjacent portion of the fixed-side end plate.

摘要： A scroll fluid machine that attenuates the bending stress applied to the base of a wall body having an inclined section. The scroll fluid machine is provided with a wall body inclined section in which the distance between the facing surfaces of an end plate of a fixed scroll and an end plate of a rotating scroll that face each other continuously decreases from the outer circumferential side toward the inner circumferential side. A mesh clearance that is a gap between wall bodies formed when the wall bodies mesh with each other is larger on the outer circumferential side of the inclined section than on the inner circumferential side of the inclined section. The mesh clearance is made larger by drawing the wall surface of a wall body further back toward the central side of the wall body in the thickness direction than the original wall surface profile thereof.

摘要： In order to optimise a compressor, including a compressor housing, a scroll compressor unit that is arranged in the compressor housing and has a first compressor body and a second compressor body that is movable in relation to the first compressor body, an axial guide that supports the movable compressor body to prevent movements in the direction parallel to the centre axis of the stationary compressor body and, in the event of movements, guides it in the direction transverse to the centre axis, parallel to a plane perpendicular to the centre axis, an eccentric drive for the scroll compressor unit, wherein the eccentric drive has an entrainer that is driven by the drive motor, that revolves on a path about the centre axis and that, for its part, cooperates rotatably with an entrainer receptacle in the second compressor body, and a coupling that prevents the second compressor body from rotating freely, it is proposed that the axial guide should have a carrier element, which serves as a base for supporting a compressor body base, which carries the scroll vane, of the second compressor body against an axial support face, that the axial support face should be arranged radially outward of the entrainer, and that the coupling that prevents free rotation should have at least two coupling element sets that, for their part, include at least two coupling elements, and that the coupling element sets should be arranged radially outward of the axial support face.
