ABSTRACT:
A simplified fluid pressure charge valve assembly for a pressurized mechanical refrigeration system that may be assembled to a housing portion for an automotive air conditioning system including a unitary valve stem adapted to be secured to the housing and having an internal chamber for receiving a cartridge-type valve wherein the cartridge-type valve is secured in place in the valve stem cavity and sealed against internal walls of the valve stem without the necessity for providing internal threads in the valve stem, thereby reducing variable costs in the manufacture of the assembly and simplifying assembly procedure.
