Abstract

A divert-air valve for a compressor of an internal combustion engine includes a flow housing with an inlet, an outlet, and a duct arranged therein, an actuator housing, an electromagnetic actuator with an armature arranged in the actuator housing, a control body which is moved by the electromagnetic actuator so as to close off the duct, a housing interior in which the armature moves, openings arranged in the control body, a connector housing arranged to bear axially against the electromagnetic actuator and to at least partially delimit the housing interior, a first sealing ring arranged on the connector housing, and a second sealing ring which bears against the flow housing on an axially opposite side of the connector housing. The openings fluidically connect the housing interior to the duct. The first sealing ring bears against the electromagnetic actuator.
