摘要： A fluid flow control valve in a fluid flow control circuit comprises a cavity, first, second and third ports open to the cavity, and a valve member for selectively closing the first port or the second port. The third port serves as an input for receiving fluid under pressure and the other two ports serve as to outputs for this fluid each extending to an associated outlet. A solenoid causes an armature to rotate about a lining so that a lever on the armature is arranged for selectively opening and closing the outlets to close the output associated with this outlet. The valve member is responsive to pressure drop at one or other of the outlets to close the output associated with this outlet. Downstream of the valve there are ducts extend from between the input and each of the outlets for supplying fluid received from the input.
