Abstract

1. Actuating device for pressure-operated, especially pneumatically operated doors in vehicles, such as omnibuses and the like, having at least one pressure-controlled two-chamber working cylinder (14, 15), actuating a door wing (10, 11) in each case and having an electrically controlled door valve (24) which, for door-wing actuation, connects the pressure-medium chambers (16-18) of the working cylinder alternately to a pressure-medium reservoir and to a relief point (35), characterized by a switching valve (34) with two switching positions, which is arranged in the connecting line from at least one pressure-medium chamber (16-18) of the working cylinder (14, 15) to the pressure-medium reservoir (31) and, in its one switching position, switches through the connection between pressure-medium chamber (16-18) and pressure-medium reservoir (31) and, in its other switching position, relieves the pressure-medium chamber (16-18) of pressure medium, and in that a control device (40), which generates controlled pulses of a given, preferably constant frequency with variable pulse duration, is connected to the control input of the switching valve (34).
