Abstract (en)

A control valve for variable displacement compressor that prevents fluid fixation between a rod and a guide hole is provided. A first rod (89) extends through a first guide hole (88) to couple a bellows (87) to a valve body (74). A second rod (96) extends through a second guide hole (95) to couple a movable iron core (93) to the valve body (74). Tapered surfaces (89b, 96b) are formed on the outer surfaces of the first and second rods (89, 96). The space between each tapered surface (89b 96b) and the inner surface (88a, 95a) of the corresponding guide hole (88, 95) is wider in the vicinity of a high pressure zone (73, 90) than in the vicinity of a low pressure zone (84, 91). <IMAGE> <IMAGE> <IMAGE>
