Abstract

A pneumatic tire valve device is constructed and arranged for attachment to a tire to change the tire pressure. The device includes a tire valve body housing, tire closing valve, and control piston. The housing defines a control piston channel that spans between a pressure pipe intake opening and a bleeding outlet and a tire intake opening that intercepts the control piston channel. The tire closing valve is positioned in the tire intake opening and is operable between an open position wherein air flows into or out of the pneumatic tire and a closed position wherein air is blocked from flowing into or out of the pneumatic tire. The control piston is positioned in the control piston channel and is operable between an idle position wherein air is blocked from flowing out of the bleeding outlet and a tire ventilation position wherein air flows out the tire and the bleeding outlet.

Claims

1. A pneumatic tire valve device constructed and arranged for attachment to a pneumatic tire to increase or decrease tire pressure in the pneumatic tire, the pneumatic tire valve device comprising:

a tire valve body housing defining a control piston channel that spans between a pressure pipe intake opening and a bleeding outlet, the tire valve body housing further defining a tire intake opening that intercepts the control piston channel;

a tire closing valve positioned in the tire intake opening, the tire closing valve is operable between an open position wherein air flows into or out of the pneumatic tire and a closed position wherein air is blocked from flowing into or out of the pneumatic tire; and

a control piston positioned in the control piston channel, the control piston is operable between an idle position wherein air is blocked from flowing out of the bleeding outlet and a tire ventilation position wherein air flows from the pneumatic tire and out the bleeding outlet.
