Eb is the object of the invention, besohriebensn in the main application To improve damper and in particular his To make damping adjustable in a simple manner. By the solution to this problem is i.a. of? Advantage achieved that by setting the damping, the sequence of a pulsating control element can also be regulated.

The problem is solved by the fact that between the chambers the Bollen membrane is arranged a partition with at least one opening acting as a throttle gap and the passage cross-section this opening can be changed by a regulating screw. .

In a first preferred embodiment of the invention it is provided that the partition wall has a reinforced band which clamps the rolling diaphragm on the housing and has a threaded hole for receiving the regulating head.

Another embodiment of the invention is characterized by this from, äa3 as a partition wall one with the rolling diaphragm in one piece connected, annular lip is provided.

In Pigo 3, which only reproduces the _{area of FIG. 1 bordered by a circle 9} , a variant of the invention is shown, as can be seen from FIG A recess in the form of a notch 36 extending over a small angular region. The recess can also be designed as a ring groove extending over the entire circumference of the socket 11. A certain damping characteristic of the control organ 1 can be achieved by appropriate dimensioning of the recess designed as a notch or ring groove. Once the nüialioh AuOanraantel the bush 11 boini reciprocation of the control member 1 with its Zo example, as a notch in the partition wall 21 comes in the recess 36 formed Bereioh the central opening 21a, the notch 36 acts as Hili'sspalt, so that not now only through the openings 26 the liquid is exchanged between the chambers 33 and 34, but also through the now opening auxiliary gap. In this way, the damping is changed at a certain moment of the periodic back-and-forth movement of the control unit. It goes without saying that the appropriate shaping of the auxiliary gap and the arrangement on the socket 11 at different levels result in any Dapfunga character let what wiailaruia can be of particular importance for Mollraiasctiiaeß »
