ABSTRACT:
A control system for the engagement and disengagement of exhaust gas turbochargers, in which the charging air pressure acts as control magnitude on a first control end face of a slide valve member against the force of a spring; in order to prevent the effects of the strong pressure fluctuation of the charging air pressure, which occur during engagement and disengagement of an exhaust gas turbocharger, on the shifting behavior of the control device, the slide valve member includes a second control end face, on which a second control pressure acts temporarily; the second control pressure and the first control pressure and the working medium for the control system may be formed by the charging air pressure so that no additional pressure sources are required; however, by the use of a spring biased valve the second control pressure may additionally be used for the filling limitation during starting and in the range of lower outputs of the piston driven internal combustion engine.
