<P>PROBLEM TO BE SOLVED: To provide an electronic control valve of a variable displacement compressor performing rapid cooling using the maximum variable displacement at the initial stage of operation of an air conditioner in the variable displacement compressor for use in a vehicle air-conditioning device. <P>SOLUTION: In this electronic control valve of a variable displacement compressor, by improving a valve rod structure, operation relation with a plunger side, and a flow passage shape, a new variable displacement control system feedbacking a pressure of a crank chamber at the initial stage of operation of the air conditioner to secure the actuation of the air conditioner and the maximum variable displacement is used to shorten warm-up time at the initial stage of operation of the air conditioner. In particular, the structure of a plunger member and arrangement relation with peripheral components are simplified to reduce the entire size by the reduction in the number of components. A plunger seat of a nonmagnetic material or the like is adopted to achieve cost reduction and improvement in durability and functionality. <P>COPYRIGHT: (C)2013,JPO&INPIT |
