The invention relates to a device (100) for damping pressure forces in the form of an impact absorber which is designed to be reversible even in the event of dynamic impact loads. The aim of the invention is to provide a device which is designed to absorb shocks in a reliable and reversible manner during normal operation and in the event of an overload. This is achieved by a device for damping pressure forces, said device having a valve arrangement (40) with an overflow region (41) which is connected to a rear hydraulic chamber region (12) and is designed such that hydraulic fluid can flow from the rear hydraulic chamber region (12) into a front hydraulic chamber region (13). A throttle pin (30) protrudes into a connecting region between the rear hydraulic chamber region (12) and the overflow region in order to control the flow speed of the hydraulic fluid from the rear hydraulic chamber region (12) in the direction of the overflow region (41). The throttle pin (30) can be converted from a first state in which hydraulic fluid can flow from the rear hydraulic chamber region (12) into the overflow region (41) into a second state in which the rear hydraulic chamber region (12) is separated from the overflow region (41) in a fluid-tight manner. Additionally, the valve arrangement (40), which is formed at an end region of the hollow piston, has an overload valve (60) which is connected to the rear hydraulic chamber region (12) via at least one overload channel (62).
