Patent ID: 7273066

Claim:
A valve connector for coupling with inflation valves of vehicle tires, comprising a housing, within the housing a coupling hole for coupling with an inflation valve, the coupling hole having a central axis and an outer opening, an activating pin, which is arranged coaxially with the coupling hole, for depressing a central spring-force operated core pin of the inflation valve, a pressure port which is connected to a pressure source, wherein the activating pin is shiftable between a proximal pin position and a distal pin position so as to depress the core pin of the inflation valve in its distal pin position and disengage the core pin of the inflation valve in its proximal pin position the activating pin is coupled with a piston and the piston is slidingly arranged in the cylinder and is movable between a proximal piston position, which corresponds to the proximal pin position, and a distal piston position, which corresponds to the distal pin position, wherein the piston is disposed between the pressure port and the coupling hole and is drivable from its proximal piston position to its distal piston position by the pressure from the pressure source, and a flow path through the piston and through at least a portion of the activating pin, wherein piston motion to the proximal piston position blocks said flow path and piston motion to said distal position opens said flow path.
