The present invention relates to a fluid control valve assembly, and more specifically, to a fluid control valve assembly for controlling a flow rate of a fluid circulating an engine of a vehicle.
A valve assembly used in an air-conditioning system of a vehicle is a valve constituting a 3-way or 4-way fluid doorway and is an automatic control valve combined with a control motor to change a flow path of a fluid and also control a flow rate of the fluid.
Such a conventional valve assembly is installed to have a compressor, a heater core, and a flow path and controls a flow of a fluid (cooling water or coolant) circulating an engine of a vehicle to adjust an indoor temperature by allowing the fluid to be introduced into the heater core or bypass the heater core.
A valve assembly is formed as a single assembly by integrating a housing in which a plurality of fluid ports are formed, a rotor which changes a flow path of a fluid, a sheet member preventing leak of the fluid, and an actuator for driving the rotor.
