Base for compressor housing

A compressor includes a housing, in which a compression chamber is provided; an injection pipeline installed in the housing and configured to inject a fluid into the compression chamber; and a solenoid valve installed on the injection pipeline in the housing and configured to allow or block off the injection of the fluid through the injection pipeline.

Compressor and method of controlling the compressor

The disclosure provides an oil tubing installation assembly and a scroll compressor adopting the same. The oil tubing installation assembly is adapted to be installed into a shell in a vertical direction and includes: a housing on which a vertical oil tubing installation surface and an oil hole located in the oil tubing installation surface are provided; a clip adapted to be installed on the oil tubing installation surface and into the shell along with the housing; and an oil tubing assembly adapted to be installed into the clip in a vertical direction after the housing and the clip have been installed into the shell. The oil tubing assembly includes an oil tubing body and a cuboid-shaped installation block. A through hole is provided in the installation block and the through hole is configured to have a first orifice on the front surface of the installation block and a second orifice on the rear surface of the installation block. The upper end of the oil tubing body is connected to the first orifice. The second orifice is aligned with and fitted to the oil hole after the installation block is installed in place in the clip. In this way, the long oil tubing can be easily installed manually in place even after the housing has been pressed into the shell.

Oil tubing installation assembly and scroll compressor

The present invention discloses a scroll compressor. At least two shrink belts (') are provided around the outer periphery of said fixed scroll between the outer periphery of said fixed scroll () and the inner wall surface of the upper cap () of the scroll compressor. The at least two shrink belts are annular, and are in interference fit between the outer periphery of said fixed scroll and the inner wall surface of the upper cap. The at least two shrink belts include a main shrink belt () and an assistant shrink belt (&#x2032;). The main shrink belt and the assistant shrink belt are arranged side by side in the axial direction, that is, in the vertical direction of the fixed scroll, and the main shrink belt and the assistant shrink belt are spaced apart from each other by a distance. In this way, it is allowed to add other special structure (e.g., an additional fluid passage) to the fixed scroll, reduce the deformation of the fixed scroll, and improve the performance and the reliability of the scroll compressor.

Scroll compressor

Embodiments of the present disclosure provide a scroll compressor. The scroll compressor includes: a fixed scroll having an end plate and a fixed scroll wrap extending from the end plate; an orbiting scroll having an orbiting scroll wrap, the orbiting scroll wrap being engaged with the fixed scroll wrap to form a plurality of compression chambers for compressing a medium; a channel formed in the end plate of the fixed scroll, the channel leading to one compression chamber of the plurality of compression chambers; and a valve provided on the end plate of the fixed scroll, and configured to open when a pressure in the one compression chamber is higher than a predetermined pressure threshold so as to allow the medium in the one compression chamber to flow out of the one compression chamber through the channel. The scroll compressor according to the embodiments of the present disclosure, for example, can improve the performance of the scroll compressor.

Scroll compressor comprising a valve provided on a fixed scroll that opens at a certain pressure

A scroll compressor is disclosed. The scroll compressor includes an shell, a fixed scroll, a housing and an orbiting scroll. The fixed scroll and the housing are disposed in the shell and fixed relative to each other. An outer peripheral surface of the housing and an inner peripheral surface of the shell are fitted to each other. The orbiting scroll is disposed between the fixed scroll and the housing. The fixed scroll is formed therein with a first injection passage, the housing is formed therein with a second injection passage, a port of the first injection passage and a port of the second injection passage face each other, so that the first injection passage and the second injection passage communicate with each other. The scroll compressor further includes an injection tube assembly, the injection tube assembly is disposed in the shell. The injection tube assembly includes: a tube, and a first tube joint and a second tube joint respectively disposed at two ends of the tube, the first tube joint passes through the shell to communicate with the outside, and the second tube joint is inserted and fitted in the second injection passage.
