ABSTRACT:
A combination vent and shut off valve for use in conjunction with a vessel having pressurized fluid therein, comprising a stem having a hollow cylindrical body portion with its inner end connected to an opening in the vessel. A stem head portion extends from the outer end of the stem body, and has a hole extending therethrough in alignment with the hollow body, the head portion having an outer diameter greater than that of the hollow body so that a shoulder is formed where the stem body and stem head meet. The outer end of the head terminates in an annular guide member having a diameter greater than the head. The head is provided with a fluid feed slot connecting the head hole with the outside of the head. A resilient cap is assembled onto the stem for reciprocation thereon and comprises a cylindrical hollow body sized to slidably fit over the stem head guide, said cap body having a closed end and an open end. A resilient annular flange extends from the inner face of the closed end of the cap body and resiliently engages the top of the stem head guide. The open end of the body has an internal annular closure member fitting loosely around the stem body. The closure member snugly engages the outer edge of the stem shoulder under the pressure created by the cap flange bearing against the top of the stem guide whereby upon the directing of pressure on the closed end of the cap toward the vessel, the flange will be compressed and allow the cap closure to move away from the stem shoulder.
