Abstract
A limit stop with an elastomer resilient element, which is to be secured on a door or lid and/or on an opposing stationary vehicle section for damping forces generated when the door or lid strikes stationary chassis parts of a motor vehicle. The limit stop includes an additional damping section disposed adjacent to and cooperating with the elastic resilient element in a spring deflection direction of the resilient element. The damping section comprises at least two chambers filled with a fluid and a nozzle plate arranged between the chambers with at least one channel extending through the nozzle plate and connecting the chambers. The fluid is displaced from one of the chambers into the other chamber during a spring deflection of the elastomer resilient element, thereby producing a pressure force which is caused by the buildup in pressure when the volume of one of the chambers decreases and augments the return force of the resilient element.
