In a tire valve for the rim () of a pneumatic tire on a vehicle comprising a valve body () of a rigid material and a valve insert () and an air outlet (), which is disposed at a spacing in relation thereto, of a flow path (), a slider or plunger () including the flow path () is mounted movably in the valve body () and the flow path is adapted to be connected at one end selectively to one of at least two air outlets () provided on the valve body. The cup-like valve body () which comprises rigid material, in particular a metal material, has a wall () and a bottom plate portion (). In addition the plunger () is to be provided with the valve insert ().

Tire valve for the rim of a pneumatic tire on a vehicle

In a device for measuring a tire pressure in a pneumatic tire of a vehicle by means of a measurement value sensor which is acted upon by the tire pressure and which is associated with a receiver, at the rim bed of a rim for the pneumatic tire, which rim accommodates the tire valve, connected to the tire valve which has a retaining nut is an electronics or signal housing which is associated with the rim base and which has base bar portions and which includes an electronic transmitter device as the measurement value sensor for the tire pressure and is connected to the tire valve by a hollow screw engaging into the valve bore and can be adjusted with respect thereto. Disposed at the inside of the retaining nut is projection as a desired-rupture element, and the base bar portions of the signal housing are pressed against the rim base by the hollow screw. The projection belongs to an installation portion at the inside surface of the retaining nut and is in the form of a leg provided at that inside surface.

Device for measuring the tire pressure in a pneumatic tire of a vehicle

In an apparatus for measuring the tire pressure in a pneumatic tire of a vehicle by means of a measurement value sensor, which is acted upon by the tire pressure, on the rim bed (12) of a rim (10), which accommodates a tire valve (20), for the pneumatic tire, connected to the tire valve (20) is a signal housing (44) which is associated with the rim bed (12) and which includes an electronic sender means as the measurement value sensor for the tire pressure. The signal housing (44) is connected to the tire valve (20) by a hollow screw (40) which engages into the valve bore (28) and is adjustable relative thereto in such a way that the tire valve/signal housing combination can be used for equipping different rim cross-sections. That purpose is also served by base elements (52) which project from the underneath surface of the signal housing (44) and which sit on the rim bed (12) and which with the suspension point on the screw (40) form a multi-point mounting configuration.
