ABSTRACT:
A filling connector for fastening to a valve arrangement on a gas container to enable filling of the gas container with a gas. The filling connector includes a housing defining a longitudinal axis, with a recess formed through a side of the housing to receive the valve arrangement of the gas container. A bore is formed in the housing parallel to the longitudinal axis, with the bore extending from one end of the housing and opening into the recess. A shaft portion is fixed to the housing in the bore, and an outer surface of the shaft portion is spaced from an interior surface of the housing which forms the bore to define a space between the outer surface and the interior surface. A piston is slideably disposed within the bore, with the piston including a sealing neck extending into the recess and a skirt portion disposed within the space and slideable on the outer surface of the shaft portion. A biasing spring is interengaged between the piston and the housing so as to bias the piston in a direction away from the recess. The biasing spring is disposed around the outside of the piston whereby the biasing spring is not wetted by the gas flowing through the filling connector.
