: 3. 4th

Another advantage of the several chambers 1 according to the invention, the plates 4 can be a control device is that the release and locking are released either in or in combination,
ment of the individual plates extremely soft and noisy. In the device shown in Fig. 2, the poor and that a very plate 4 connected to locking levers 6 for their adjustment, the low force is sufficient because the pressure medium on 5 in turn with adjusting levers 7 one Lochers act together with the bearing surfaces of the housing parts. In accordance with the in F i g. 1 film forms. Each housing part forms the arrangement shown

An advantageous embodiment of the two halves of the invention of two adjacent chambers, any one The facility consists in the fact that the plate is only connected to the pressure line on the right Pressure equalization between the two halves is connected to the chamber half on the side. Through in the the chamber is perforated. This eliminates the need for a plate 4 holes arranged by the print discarded person Feeding of the pressure medium into each of the same between the two chamber halves one two chamber halves formed by the plate. Chamber instead.

Furthermore, it is advantageous to use flexible strips 8 to support one another by means of flexible strips 8, which are suspended from a rod 9 under the force of a single spring, and spacer rings 10 are located between the housing parts held together by several cam strips 8 To form the mern. In this manner is obtained with very housing parts are an extremely compact sammengedrückt by a leaf spring 3 α zugeringem cost of materials, the pressure force is adjustable by means of a gelschraube ReAnordnung. 11
