Abstract (en)
[origin: EP0115337A2] The invention relates to a method of setting the speed of a drive unit operated by a gaseous pressure medium, in particular compressed air, characterized in that the gaseous pressure medium, during a working operation, is fed into the drive unit and/or discharged in a pulsating manner at least intermittently, preferably during the entire working operation. Furthermore, the invention relates to a device for carrying out the method, characterized by a drive unit (1) which is connected via a compressed-air line (2) to an electrically actuated solenoid valve (3) which is connected by an electric cable (4) to a programmable logic controller (5). <IMAGE>
