Abstract
The invention relates to a support bearing (10) with a damping channel linking a working chamber (11) and a compensation chamber (12), said damping channel being provided with a damping channel orifice (14) that can be opened and closed with a plug (15). Until now, high pressing forces were required to keep the damping channel orifice (14) closed with the plug (15) at peak pressures. The object of the invention is to reduce markedly the pressing forces with which the plug (15) must be pressed against the damping channel orifice (14) at peak pressures. In the support bearing (10) of the invention, the plug (15) can be pressed against the damping channel orifice (14) from the direction of the working chamber (11).
