A connection for extensions for vehicle tire inflating valves comprises a body consisting of two portions, one of which is to be joined with the extension and the second is to be connected to the valve and ends in an appendage for actuating the valve moving element. The second portion of the body comprises a cylindrical element with a smooth side surface having, near the appendage, a radially operating sealing ring.
An inflation device includes a first section having a threaded recess for receiving a valve of an object to be inflated, and a flange extends radially inward from an inner periphery of the first section. A tunnel is defined through the flange and an insertion of a second section extends through a rear end of the first section and is movably engaged with the tunnel. An end member with a path is connected to the insertion and a passage is defined through the second section. The end member is movably inserted in the threaded recess to push a seal pin of the valve in the threaded recess while the valve is air-tightly received in the threaded recess.
A valve stem assembly for use with a pneumatic tire includes a stem, a first quick couple connector and a second quick couple connector. The first quick couple connector is attached to the stem. The first quick couple connector includes a first valve therein. The second quick couple connector is detachably coupled with the first quick couple connector. The second quick couple connector opens the first valve when the first quick couple connector and the second quick couple connector are coupled together. The second quick couple connector includes a second valve therein.
