Abstract
A multiple use valving device for use between a fluid flow source and at least one device utilizing the fluid flow including a valve housing having at least one inlet and one outlet connected in fluid communication by a channel therebetween. A deformable but resilient sealing member is positioned within the housing with respect to the channel so that when a manual control member is moved from an open to a closed position, an actuator responsive to the manual control member deforms the sealing member to block the channel to prevent any fluid transmission. By moving the manual control member back to an open position, the actuator is released and the resiliency of the sealing member pushes it away thereby opening the channel for fluid transmission. The valving device can consist of as few as one inlet, one channel and one outlet, or may consist of any variation of inputs and outputs, such as one inlet and a plurality of outlets each having its own channel in communication with the inlet and each having its own manual control member and actuator. Additionally, there can be two or more inlets each having any number of outlets and corresponding channels according to desire or need.
