Abstract:
An activation pin for a valve connector for connecting to inflation valves, the connector comprising:a housing to be connected to a pressure source; the housing having a coupling hole having a central axis and an inner diameter approximately corresponding to the outer diameter of the inflation valve to which the valve connector is to be connected; a cylinder and means for conducting gaseous media between the cylinder and the pressure source; where the activation pin is positioned to engage a central spring-force operated core pin of the inflation valve; the pin is situated within the housing in continuation of the coupling hole coaxially with the central axis thereof; where the activation pin comprises: a piston part with a top and a piston, the piston positioned in the cylinder movable between a first piston position and a second piston position; a central channel, said piston part comprises a first end and a second end, wherein the piston is located at said first end and said channel has an opening at said first end; a valve part being movable in the central channel and drivable, by a difference in forces acting on surfaces of the valve part, between a first valve position and a second valve position, wherein said first valve position leaves said opening open, and said second valve position closes said opening; and, the top of the piston part forming a valve seat for a seal face of the valve part.
