Abstract
A cap for closing an upwardly facing, neckless opening in a vehicle radiator comprises a shell defining a chamber within the cap. The shell includes an outer end disposed without the radiator when the cap is closing the opening and an inner end disposed within the radiator when the cap is closing the opening. A first venting passageway in the outer end of the shell connects the chamber to atmosphere, and a second venting passageway in the inner end of the shell connects the chamber to the radiator interior. An outwardly facing valve seat is disposed within the chamber and a pressure-vacuum valve is urged against the seat by a spring, the valve and spring being housed within the chamber. The seat is provided by an integral annular portion of the shell which extends peripherally and radially inwardly from an interior wall of the shell. A plurality of ears for engaging the radiator opening are disposed about the outer periphery of the shell and project radially outwardly therefrom. The projecting ears can be disposed adjacent the inner end of the shell, or can be disposed intermediate the inner and outer ends of the shell. The shell desirably is formed of molded plastic and is molded in two pieces. An outer piece includes the shell outer end and a portion of the shell side wall. An inner piece includes the shell inner end, a portion of the side wall, the engaging ears and the pressure-vacuum valve seat. The valve member and spring are placed between the two pieces which are then joined to assemble the cap.
