  • a filling connection for gas cylinder valves in particular of acetylene cylinders, is advantageously created, which has a housing with a filling inlet and with a cylinder valve attachment and retaining projection, in which a filling outlet is formed.
  • a bottle valve connecting piston sleeve is sealed in the housing and can be displaced against a spring, the connecting piston sleeve having a valve body with a passage which is biased into its sealing position by a spring and which, after connection to the bottle valve, releases a filling passage through the housing.
  • the connecting piston sleeve itself is advantageously held securely and reliably by a device in its rest position before connection to the bottle valve and in its connection position after connection to the bottle valve.
  • the filler connection according to the invention can be connected to and disconnected from gas cylinder valves extremely quickly and easily due to this embodiment according to the invention, and non-specialists can safely handle the filler connection due to the advantageous interaction of the functional elements.

  • a guide and actuating member is provided for the holding device, which is biased relative to the housing in the direction of the bottle valve attachment and holding molding and is preferably slidably mounted in the housing, the guiding and actuating member having the filling inlet and a passage to the valve body.
  • the guiding and actuating member has at least one cage-like passage space for an associated coupling element, the surrounding housing having associated inlet shapes with control surfaces, and the connecting piston sleeve on its outer circumference each having an associated securing recess at least for the position of the connecting piston sleeve before connecting to the cylinder valve.
  • the connecting piston sleeve is reliably held in an associated securing recess by the engagement of at least one coupling element before being attached to the gas cylinder valve, the engagement of the coupling element being secured in a simple and reliable manner in this position by the control surface provided on the housing.
  • the handling of the filling connection is extremely simple, since after the filling connection has been attached, the connecting piston sleeve can only be brought into engagement with the gas cylinder valve by releasing the exit of each coupling element from the safety recess due to its pretension.
  • connection piston sleeve can be in its position after connection to the cylinder valve in the same way by means of a form-fitting device, optionally using it same coupling element can be secured.
  • the connecting piston sleeve has on its outer circumference an engagement surface for the non-positive engagement by each coupling element on the part of the control surfaces on the associated inlet shapes of the housing.
  • the combination of positive engagement in the connecting piston sleeve before connection and non-positive holding of the connecting piston sleeve after connection is particularly advantageous because it always achieves an optimal insertion position of the connecting piston sleeve in a gas cylinder valve socket due to the prestressing of the connecting piston sleeve relative to the guide and actuating member, this optimal engagement or engagement position is then secured by pressing the coupling element onto the outer piston sleeve engagement surface with a force which results from the pretensioning of the guide and actuating member relative to the housing.
  • each coupling element preferably, and in a particularly easy-to-use manner, each coupling element consists of a ball.
  • Usable balls of the required hardening and suitable size are commercially available at high quality, so that this simple construction element can also be used to achieve favorable manufacturing conditions for the filler connection.
