Abstract:
An activating pin for a valve connector for connecting to inflation valves, the connector comprisinga housing to be connected to a pressure source, within the housing 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, and a cylinder and means for conducting gaseous media between the cylinder and the pressure source, and which activating pin is arranged for engaging with a central spring-force operated valve lever of the inflation valve, is arranged to be situated within the housing in continuation of the coupling hole coaxially with the central axis thereof and comprises a piston part with a piston, which piston is to be positioned in the cylinder movably between a first piston position and a second piston position, whereinthe activating pin further comprises a valve part, the piston part comprises within it a channel, the cross-section of said channel is, at least one part of said piston part, flower-shaped, consisting of essentially identical sectors, wherein in each sector the distance between the center point of the channel cross-section and the outermost limiting surface of the channel is larger than the corresponding distance measured along the line separating the sector from and adjacent sector, and said valve part is positioned movably with respect to said piston part, between a first valve position and a second valve position for enabling the conduction of gaseous and/or liquid media through said channel when said valve part is in said first valve position, and inhibiting the conduction of gaseous and/or liquid media through said channel when said valve part is in said second valve position.
