A pressure plate 19b is located on the one in the membrane chamber 20b protruding end of the plunger 16b. A stopper 22b serving as a rotation lock is in at least one radial opening of the threaded piece 12b arranged. In the lid Yb is a Yerschlußstück 23b with a polygonal actuator 24b .und one Opening 25bs the space of the memory spring 6b with the Atmosphere connects, screwed in.

A diaphragm 26b is firmly clamped between an upper part 2b with ', an inlet 27b and a bottom 3b of the diaphragm cylinder ".2b,' 3b ^ and can rest against a diaphragm plate" 28b.- ■ ₉ which is positioned against the via a return spring 29b Base 3b and a piston rod 30b with a fastening 31b for a brake linkage (not shown). An annular stop 32b for the diaphragm plate 28b is fixedly arranged on the base 3b.

The mode of operation of the embodiment of the release device shown in FIG. 3 is as follows

In the position shown, compressed air is applied to the pressure chamber 9b via the inlet 8b. The piston 4b compresses the accumulator spring 6Tb via a brake valve (not shown) Operational braking can be initiated. If the compressed air falls out of _g , the pressure chamber 9b is depressurized ₉ and the accumulator spring 6b. ■ moves the piston 4b to the right. Here the tube-like

■: If the pressure chamber 9b is acted upon by the recurring compressed air, when the threaded piece 1 2b with the plunger 16b within the tubular elongation has been moved all the way to the right again, this allows the force-fit connection of the piston 4b - with the tubular extension 10b by means of the spring 14b, a relative movement of the piston 4b with respect to the tubular extension 10b to the left ₉ as soon as the pressure plate 19b is in contact with the upper part 2 \. ■ "■ -.
