Abstract

A valve for fluids employs two telescoping parts which cooperate with one another to block fluid flow when pulled partially apart and open a flow path therethrough when pushed together. A plunger component, having a central bore, a closed off end and perforated walls, is slidingly and sealingly received within the collar of the hollow valve body. When the plunger's closed end is pushed far enough into the valve body so as to expose the apertures, fluid is free to flow from within the valve body into the plunger component. When pulled apart so as to cause the perforations to be positioned within the confines of the collar, flow is blocked. An actuation mechanism integrated into a housing serves to automatically pull the valve's components apart to stop flow when its cover is swung open and conversely causes the two components to be pushed together to open flow when the cover is closed.
