Abstract
In the process, a spring device is pivotally connected to a transmission lever which is movable between two defined positions. The free end of the spring device is subjected to a defined load and is fixed stationary while the transmission lever is in the defined position corresponding to the closing position of the valve. Thereupon, the length of the prestressed spring device is fixed, which results after swiveling of the transmission lever into the other defined position. The effect of the spring tolerances on the precision of adjustment of the change-over point is excluded. The brake pressure control unit apparatus is provided with first and second stop elements fastened to the spring device with a removable spacing element inserted between the stop elements. The distance between the stop elements corresponds to a determined amount of spring preload fixed by the spacing element.
