ABSTRACT:
A connector assembly is disclosed for connecting a source of fluid, such as a refrigerant, with a container, such as in an air conditioning system. The assembly includes an elongated tubular body having a fluid passageway extending axially therethrough from an inlet to an outlet. A depressor is located in the passageway intermediate the inlet and outlet and is mounted for slidable movement between a normally valve closed first position and a valve open second position. A ball valve check assembly is located within the passageway in the tubular body between the inlet and the depressor. This assembly includes a spool having a spool passageway extending axially therethrough. The spool passageway has a first portion and a second portion with the second portion being located downstream from the first portion and being of a smaller diameter. A radially extending shoulder interconnects the first and second portions. A resilient ball having a diameter greater than the second passageway portion but less than the first passageway portion is located within the first portion. A spring normally resiliently biases the ball member against the shoulder to prevent passage of fluid through the spool passageway. The depressor has an actuator for engaging the ball member and displacing same against the resilient bias of the spring. This opens the ball valve assembly to permit fluid flow from the inlet to the outlet.
