Abstract
A pedal-operated valve is provided controls the rate of fluid flow in a soft hose. A cradle positions a section of the hose so that its cross-sectional area can be compressed by the hinged rotation of a pinchcock toward the cradle in response to a pedal force to reduce the rate of flow. The compressed cross-section expands in response to the internal fluid pressure of the hose upon release of the pedal force to increase the rate of flow. A latch secures the pinchcock in an angular orientation relative to the cradle to maintain the reduced cross-sectional area. A lever is pedal operated to disengage the pinchcock from the latch.
