Abstract
A pinch valve is provided which includes an outer housing into which lower and upper elements are positioned. A flexible, tubular shaped hose, duct, or similar conduit or line to be used under pressure is inserted into and maintained between a support section of the lower pinch element and a support section of the upper pinch element. A resilient spring located between the lower pinch element and the bottom surface of the outer housing compresses the flexible line into a closed position, in order to maintain an effective and leak proof closure of the line. When it is desired that the pressurized line be opened and fluid in the line be permitted to flow, an actuating button located atop the outer housing is pressed. The resulting pressure acts against the compressive force of this spring, causing the lower pinch element to move down within the housing, thereby opening the flexible line to permit fluid flow. When pressure is removed from the actuating button, the compressive force of the spring once again compels the lower pinch element upward, thereby closing the line.
