Abstract
The invention provides a displacement control valve for a variable displacement compressor comprising: a valve housing having a discharge chamber connecting space and a crank chamber connecting space; an electronic solenoid; and a valve body configured to reciprocate within the valve housing the electronic solenoid. The displacement control valve is opened and closed when the valve body moves from the discharge chamber connecting space toward the crank chamber connecting space, making it possible to enlarge a cross-sectional area of the valve body and improving productivity.
