F16K 15/14

Abstract:

The present invention provides a novel pinch valve structure that allows for controlled dispensing of liquids, gases, and other flowable materials. The present invention address issues with current valves with an innovative structure that prevents leakage and spillage, and improves efficiency and ease of use. The pinch valves of the present invention may include a resilient compressible body with a distal drainage hole, a resilient actuator comprising at least two spring-like, resilient arms, a central piston member mechanically connected to the resilient arms, and a distal plug mechanically connected to the central piston member for engaging with and blocking the distal drainage hole.
