Abstract

A combined charge/relief valve for an air conditioner system includes an outer housing that defines a first passageway and an inner housing that defines a second passageway. The inner housing includes an O-ring seal and is biased by an outer spring to a sealed position to seal the first passageway. The inner housing can be moved to a charging position by the direct application of mechanical force in order to facilitate high rate charging of the air conditioner system. The inner housing includes a valve member movable between an opened and a closed position to seal the inner passageway. The valve member is biased to the closed position by a precision relief spring. Excessive refrigerant pressure in the air conditioner system moves the valve member from the closed to the open position in order to vent refrigerant to the environment.
