Abstract

In a power control valve assembly in which the position of an inlet valve member relative to its seat is controlled by a control rod extending through a passage terminating in the seat, an end portion of the control rod has a profile which gives a variable throttling of flow through the passage in dependence upon the axial position of the control rod. In the valve described the end portion of the rod has an end part of constant diameter connected to a further part of reduced diameter by a sloping shoulder. Two such valve assemblies are shown arranged in parallel and operated through a single resilient block and a balance beam.
