Ig / means arranged between (Jpif f and hammer head are*

The horizontal door control improves the shock-absorbing end Effect of such resilient means considerably through better ones Design

According to the resilient means, there are two in each case Spring elements are used whose directions of action are opposite are; in particular, such means are used for such means Springs are used that are largely free of inherent damping, So for example very helical compression springs.

Hetter according to the place of such a spring arrangement but also one equipped with a double direction of action Spring can be used, for example a single or preferably educational leaf spring, and especially one with noticeable and, if necessary, adapted to the requirements ligendampfung »
