<p>A fluid mixing valve comprising a housing provided with two fluid inlet ports and an outlet port for discharging fluid from the housing, a valve member within a bore in the housing axially movable in the bore for controlling fluid flow from the inlet ports to the outlet port and rotatable in the bore for controlling the relative volume rates of flow through the two inlet ports. The valve member is provided with two arcuate control surfaces eccentric in relation to the axis of rotation of the valve member and each co-operable with separate ones of the ports for inversely controlling, responsive to rotation of the valve member, the relative rates of flow through the individual inlet ports. Preferably one of the control surfaces co-operates with one of the inlet ports and the other co-operates with the outlet port for controlling relative fluid flow through the two inlet ports. The valve member may be controlled by a handle pivoted to a head for pivotal movement about a support axis extending at right angles to the valve member axis, the head being pivotally secured to the valve member whereby pivotal movement of the handle about the support axis causes axial movement and rotational movement of the head causes rotation of the valve member in the housing.</p> |
