Abstract
In order for charge air to be conducted with the lowest possible losses in pressure in a turbocharger including a blow-off valve, a flow-guiding element in an inlet region is designed such that neutral zones are formed at the flow openings. The flow openings recirculate charge air from the pressure side to the suction side when the blow-off valve is opened. The flow-guiding element avoids vortices and therefore losses in pressure in the region of the flow openings.
