ABSTRACT:
A device to control the flow of fluid uses a cam and ratchet wheel. A valve is operated by the cam portion of the wheel, which bears against the valve stem causing it to open. Fluid flow causes a pawl to drive the ratchet portion of the wheel, rotating the wheel until the valve stem bears against a low point in the cam, permitting the valve to close. A part of the ratchet portion does not contain ratchet teeth, in which area the pawl cannot drive the wheel. In this area, the cam has an increasing radius from a radius corresponding to a closed valve, to a radius corresponding to a fully open valve. This permits manual control of fluid flow without disengagement of the device.
