Abstract
A low pressure valve for controlling exhaust gas recirculation in an internal combustion engine for a vehicle includes a housing, which contains a channel section for exhaust gas guidance, and a valve element disposed in the housing to control the exhaust gas passage in the channel section. An actuating drive is mounted on the housing and adjusts the valve element. The actuating drive is formed of an electromagnetic rotary actuator with a drive shaft thereof. The drive shaft is routed in an extended manner out of a rotary actuator housing and is in the form of an actuating shaft. The actuating shaft extends continuously to the housing and protrudes into the housing transversely to the flow direction, engages therein at the valve element in a non-rotatable manner and can be rotationally adjusted about the axis to actuate the valve element.
