Abstract
An apparatus for the mechanical and orificial coupling of a conventional liquid gas fuel supply container and/or supply outlet fixture to a control valve and/or similar secondary fuel outlet port. The coupling apparatus comprises a shaft modifying the inlet of a conventional control valve, which provides an extended port for orificial connection, and a plastic collar which intercalates into a conventional recessed supply outlet orifice fixture. The collar is first engaged with the supply outlet fixture which then makes a socket for the intercalation of the control valve shaft in a quick and secure bayonet fashion. No screw threads are used in any part of the engagement mechanisms.
Claims9
A coupling apparatus for interconnecting a fluid supply control valve having an inlet orifice to a fluid supply outlet fixture having an outlet orifice centrally located in a cylindrical recess formed therein, said recess having an inwardly protruding lip formed about its circumference, wherein the coupling apparatus comprises:
- a collapsible annular collar, having an outwardly protruding rib extending about its circumference, configured and dimensioned for insertion into said fixture's cylindrical recess upon collapse and wherein said rib engages the lip of said outlet fixture so as to prevent the collar's extraction from said recess upon expansion of said collar;
- and
- a hollow shaft extending from said control valve and centered about said inlet orifice, configured and dimensioned so as to be slidably insertable into said collar while said collar is in its expanded state so as to bring the inlet orifice into fluid communication with the outlet orifice, said hollow shaft including means to hook under said collar upon full insertion and relative rotation thereto whereby the presence of the shaft within the collar prevents the collar's collapse and whereby the inlet and outlet orifices are firmly held in fluid communication with one another.
