ABSTRACT:
An arrangement for regulating supercharger air pressure in a combustion engine operated with exhaust gas supercharge which equipped with an exhaust gas turbosupercharger, consisting of a supercharger and an exhaust gas turbine. The regulating device is a valve controlling an exhaust gas bypass to the exhaust gas turbine. The valve has a pressure unit divided by a diaphragm into two chambers. One side of the diaphragm is charged with supercharger air pressure, and the other side is loaded by a spring. The two chambers are connected by a calibrated opening in the diaphragm. Another valve connects the chamber holding the spring to the atmosphere and has the form of a nonreturn ball valve. The preloading of the spring of the nonreturn ball valve may be adjustable.
