ABSTRACT:
A manually adjustable service adapter includes a manually adjustable actuation shaft for opening the valve of a charging port of a refrigeration system to permit the charging of refrigerant into such system. Actuation of such charging port results from an axially movable shaft which is manually adjustable by a rotatable knob which causes the shaft to move axially opening the valve of the charging port. Means are provided for preventing rotational movement of the axially movable shaft.
