ABSTRACT:
A flow control valve for controlling liquid flow, for example, water flow in a vehicle heating circuit, has a ceramic obturator plate which slides sealingly relative to a fixed sealing plate, the two plates having openings the degree of overlap of which determines the valve throughflow. A bowed leafspring maintains the slidable obturator plate in sealing contact with a mating face of the sealing plate.
