초록 ▼

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.

대표청구항 ▼

An apparatus for controlling fluid communication between a first and a second conduit, comprising: a valve body having a first port, a second port, and an interior cavity, said cavity having a first portion having a diameter and a second portion having a diameter and a first and a second end, said diameter of said second portion being substantially the same between said first end and said second end, wherein both said first and second ports are in fluid communication with said interior cavity and said first port is connected to the first conduit, wherein said diameter of said first portion of the interior cavity is larger than said diameter of said second portion, and said first portion is closer to said first port than said second portion is to said first port; a plunger component having a closed end, a hollow interior and a third port connected to the second conduit and to said hollow interior, said plunger component having a side wall connecting said third port with said closed end, said side wall having an aperture positioned therein adapted to establish a fluid communication path between a position outside the plunger component with the hollow interior, said plunger being generally uniform in outside diameter between said closed end and the third port side of said aperture, said plunger component being inserted into said valve body through said second port closed end first so that said aperture is selectively slidably situated in said first portion and said second portion of said interior cavity; and a first seal located on said plunger component between said closed end and said aperture, wherein said first seal and said aperture are selectively locatable in said first and second portions of said interior cavity, said first seal having a size such that said first seal has an interference fit with said second portion when situated in said second portion, whereby when situated in the second portion, said first seal blocks said fluid communication between said first and second conduits; and said valve body and plunger component having exterior surfaces formed to facilitate engagement thereof by a mechanized actuation mechanism; whereby said aperture provides for fluid communication between said first and second conduits when said aperture is positioned in said first portion, and whereby said seal blocks said fluid communication between said first and second conduits when said seal is positioned in said second portion.
