TODAY’S PATENT – PRESSURE SENSOR FOR DETERMINING TIRE PRESSURE

The PRESSURE SENSOR FOR DETERMINING TIRE PRESSURE was invented by Hans Schrumpf (Oberasbach), Lothar Haas (Stein), Gerhard Hettich (Dietenhoten) on 25^th February 1992, bearing the patent number US5090237A.

The invention relates to a pressure sensor or switch for determining the air pressure in the interior of tubeless tires of motor vehicles mounted on a rim, wherein the housing of the pressure sensor or switch penetrates a corresponding recess of a rim wall and is fastened at the rim in an airtight manner of fastening devices.

A pressure sensor for determining air pressure in an interior of a motor vehicle tire has a housing for extending into a recess formed in a rim wall of the tire, and an annular flange located on the housing and supporting a spring against a side of the rim wall which spring provides for clamping an outer flange portion of the pressure sensor housing against another side of the rim wall.
