Title: FLOW CONTROL VALVE AND TEMPERATURE CONTROL DEVICE USING SAME
Abstract:
Provided are: a flow control valve from which leakage of a fluid can be suppressed when the flow control valve is fully closed, compared to a flow control valve not having a gap reducing part provided so as to partially reduce the gap between a valve element and a member facing the valve element; and a temperature control device using the same. The present invention is provided with: a valve body having a valve seat formed of a columnar hollow space where one or more valve ports each of which has a rectangular cross section and through which a fluid flows are formed; a cylindrical valve element which is rotatably arranged in the valve seat of the valve body so as to open/close the valve ports and which has an opening portion in the outer circumferential surface thereof; a gap reducing part which is provided so as to partially reduce the gap between the valve element and a member facing the valve element; and a drive means for rotationally driving the valve element.
