Activation pin for valve connector providing a reliable activation pin which is inexpensive, has low air-power resistance, and is therefore suitable for use as pump

摘要

By means of an activation pin for a valve connector, for engaging with a central spring-force operated valve lever of inflation valves of vehicle tyres, which activation pin is designed as a piston (31) in the coupling house of the valve connector with a piston rod. (32) that is slidable in the cylinder-shaped coupling house where the activation pin has a center drilling (33) and a valve (34) kept closed by a spring device (41), the aim is to produce a reliable activation pin which is cheap, has low aerodynamic drag and is comfortable to use for pumping purposes. Pursuant to the invention, this is achieved by the fact that the center drilling (33) in the activation pin has a flower-shaped cross section on the major part of the piston rod (32) and/or piston (31) length.
