[0004] In this case, such a solution creates friction that needs to be limited
However, in the known solutions there is a risk of incorrect positioning of the rings which can lead to many disadvantages

Embodiment Construction

[0034] The present invention relates to figure 1 The compressor 1 shown is used in particular to circulate and pressurize a refrigerant circulating in an air conditioning circuit, in particular for thermal regulation in the passenger compartment of a motor vehicle.

[0035] Said compressor 1 comprises a fixed part 2 and a movable part 10 movable relative to said fixed part 2 , said movable part 10 being configured to orbit around an orbital axis of rotation 4 .

[0036] More precisely, the compressor here comprises a body or housing forming said fixed part 2 , through which a rotating shaft 3 passes. The latter turns around the main axis of the compressor forming said orbital axis 4 . Should

[0037] The compressor shaft may be driven by a drive mechanism, which may take the form of a pulley in the case of a mechanically driven compressor. Such a drive mechanism is preferably an electric motor integrated into the compressor 1 . The compressor may comprise a power supply an...

Abstract

The application concerns a compressor comprising a fixed part and a part (10) movable relative to said fixed part, aid movable part (10) being configured to follow an orbital movement around an orbit axis, said compressor further comprising at least one anti-rotation assembly (20), formed of a ring (22) and a pin (24) configured to immobilize said movable part (10) against rotation on itself during its orbital movement, said fixed part and said movable part (10) being separated at least locally by a space forming an axial clearance (J), crossed by said pin (24), said ring (22) penetrating into said space.

Description

technical field [0001] The technical field of the invention is compressors, in particular air-conditioning compressors, in particular for motor vehicles. Background technique [0002] In compressors known at this time, there are different types of compression mechanisms. In one particular type, known as a scroll, a movable scroll orbits relative to a fixed scroll. Such orbital motion makes it possible to compress and impart motion to the refrigerant in the air conditioning circuit in order to thermally condition an enclosure such as a motor vehicle passenger compartment. [0003] In order to ensure the correct operation of such a mechanism, the movable scroll must be restricted from rotating itself. It is known to use multiple rings connected to the portion carrying the movable scroll for this. They are distributed circumferentially around its perimeter. Each ring is associated with a pin connected to a fixed part of the compressor. The pins are in local contact with th...
