Embodiment Construction

[0037] figure 1 with figure 2 An annular element 18 arranged in a scroll compressor is shown having a continuous notch 19 extending over the entire periphery.

[0038] The ring element 18 includes an outer peripheral surface 19 . The recess 20 extends on the outer peripheral surface 19 . The recess 20 is arranged centrally on the outer peripheral surface 19 . The notches 20 extend continuously, ie without interruption, on the outer peripheral surface 20 . The notch 20 is concave.

[0039] figure 1 with figure 2 The recesses 20 described above are designed as grooves. The groove serves as a receiving chamber for the lubricant. The recesses, especially the grooves, are filled with lubricant during operation. The ring element 18 is arranged in the cylindrical recess 16 (not shown) during operation. The lubricant causes a lubricating film to form between the ring element and the cylindrical recess 16 . The lubricant reduces the friction between the ring element 18 and...

Abstract

The invention relates to a scroll compressor comprising a casing (11) with a casing cover (12) and a casing partition (13), a movable displacer coil (14) and a non-movable anti-coils (15) which engage with each other, wherein - housing partition (13) and displacer coils (14) are arranged on the suction side, and housing cover (12) and anti-coils (15) are arranged on the high-voltage side, - at least one cylindrical recess (16) is formed on the side of the displacer coil (14) facing the suction side, and - a pin (17) is arranged on the side of the housing partition (13) facing the high pressure side, so that project into and interact with the cylindrical recesses (16) to form guides for the movable displacer coils (14), at least one of which has an outer peripheral surface (19) The ring element (18) is arranged in at least one cylindrical recess (16), wherein the outer peripheral surface (19) comprises at least one recess (20).

Description

technical field [0001] The present invention relates to a scroll compressor. Background technique [0002] Motor vehicles use nonflammable refrigerants for air conditioning to avoid the risk of an explosion inside the passenger compartment in the event of an accident. However, the refrigerants used hitherto have either been banned or at least classified as problematic refrigerants due to their high potential to cause global warming. CO 2 (R744) is used as an environmentally friendly, non-flammable refrigerant, and has partially replaced previous refrigerants. Carbon dioxide air conditioning systems work at high operating pressures. The advantage of high operating pressure is that, due to the CO 2 The density is higher, so a small volume flow is required to produce a relatively high cooling capacity. Scroll compressors are used to compress refrigerant. [0003] The working area of ​​the scroll compressor is 4cm per revolution 3 to 200cm 3 The above and pressure range ...
