Abstract

The compressed-air control device has a control-air reservoir (4) which is monitored in its pressure via at least one controllable valve (7, 8) and is filled with a filler material serving as a heat accumulator in order to avoid or moderate pressure shifts caused by thermal effects and occurring in each case after a controlled pressure change. The filler material can consist of metal sleeves, metal chips, steel wool, open-pored plastic or plastic flakes. Furthermore, a control member (10, 11) with adjustable delay value for delaying its switching can be allocated to the valve (7, 8).
