Abstract: A valve connector for coupling with inflation valves of vehicle tyres, 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, positioning means for positioning the inflation valve when coupled in the coupling hole, and 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 cylinder (303) having a cylinder wall provided with 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 relative to the positioning means 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 when the inflation valve is positioned by the positioning means, the activating pin is coupled with a piston (304) and the piston (304) is slidingly a

Abstract: An activating pin which 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, consisting of 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 an 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.

Abstract: A universal valve connector for valves of vehicle tires comprises a connector housing, partly connected to a pressure source, preferably a hand or foot pump, and has a coupling hole with a diameter corresponding to the diameter of the valve for connection, where the coupling hole has securing means, plus a sealing means against various valve sizes. The sealing means is mounted coaxially in the connector housing and established on at least two parallel levels, having the centre line of the connector housing, where the minor diameters of the sealing means correspond to the major diameter of the valve, where the connector is mounted when used. The sealing means, closest to the coupling hole in the connector housing has the biggest minor diameter, while the sealing means farthest from the coupling hole has the smallest minor diameter, and diameters between the extremes correspond to distance between these extremes.

Abstract: The purpose of the invention is to provide a valve actuator with an activating pin of a simple construction.
