Abstract

The mechanism alternately supplies a consumer unit via two passages, having a control plunger working in a cylinder. In each control position this delivers high-pressure air to one of the passages and shuts off the other one by masking control ports in the cylinder. During a control stroke and when an air passage (DA) is shut off from the high-pressure supply, it is supplied with lower-pressure air via an auxiliary passage (3). A pre-heater is provided for the lower-pressure secondary air, and the auxiliary passage is connected to the high-pressure supply by a pressure reducing unit (31) and it can contain a non-return valve (32).
