ABSTRACT:
According to the method, in a first step, an elastic shim element, of a part circular embodiment with a projection on the external side, is fixed around a throttle valve shaft. In a second step, a first insert and a second insert are introduced into the throttle valve support from both sides until each is in contact with the projection and between both and the relevant projection a cavity, surrounding the throttle valve shaft is formed. In a third step, a molten plastic is then introduced into the cavity through the first insert or the second insert, whereby the at least one elastic shim element is pressed with the projection thereof on the inner wall of the throttle valve support. After the plastic has hardened the first insert and the second insert are removed from the throttle valve support in a fourth step.
