(54)	Pivot joint for a swash plate of a variable displacement compressor

(57) A variable displacement compressor the displacement of which depends on the inclination of a drive plate (50). The compressor includes a sleeve (18) fitted on a drive shaft (16). The sleeve (18) supports a pivot joint for supporting the drive plate (50). The maximum inclination of the drive plate (50) depends on the distance (Sx) between the pivot axis of the drive plate (16) and an end that abuts against a limit stop. Therefore changing the sleeve (18) changes the maximum displacement. Changing the sleeve (18) does not alter the balance of the drive plate (50). In compressors having different displacements, all parts are the same except for the sleeve (18), which facilitates mass production.
