Abstract
A flow control valve for allowing the flow to be controlled on a proportional basis using a direct current(DC) motor thereby improving the flow control function. The flow control valve is constructed in a manner that a valve housing having a guide space and an inlet and an outlet is formed on the both sides of the valve housing, the inlet and the outlet being in communication with each other through the guide space. A spool is installed inside the guide space of the valve housing and up/down movably coupled therein so as to control the opening of the outlet. A spool guide is placed on the upper side of the guide space passing through liquified coolant by moving up/down along with the spool. A elastic support elastically supports the spool guide to one direction. A sealing member prevents the leakage of liquefied coolant by surrounding the spool on the lower side of the valve housing. A driving mechanism moves the spool up/down by use of a DC motor.
