An electromagnetic actuator, particularly for use with valves in the automotive field, such as, for example, exhaust-gas recirculation valves, secondary-air valves, etc., having a housing with an electrical connector plug, a magnetic yoke, a coil unit, a guide element, a magnetic core and an armature that cooperates with a valve adjusting member. The armature is formed by first and second armature elements, the second armature element being in the form of a disk mounted so that it is spaced from the first armature element by an air gap when current is not supplied to the actuator whereby high, abrupt force is developed on the first armature element to open the valve when current is supplied.

Electromagnetic actuator for a valve in the automotive field

The present invention pertains to an adjustable canister purge valve (,) and method having a first connection (,) for an intake pipe (,) of an engine and a second connection (,) for an activated carbon filter (,). The first (,) and second connection (,) are interconnected by means of a first adjustable valve (,) enabling the flow of a regenerating mixture (,) of air and fuel-vapor. A second valve having a larger flow cross-section (,) is connected in parallel with the first valve (,) and allows a large regeneration air flow, even with a low suction vacuum, and thus improved purge.

Canister purge valve for high regeneration airflow

The present invention provides an exhaust gas recirculation assembly. The exhaust gas recirculation assembly includes a single housing having an integrated airflow passage, a recirculated exhaust gas passage, and valve mechanism. The airflow passage is operatively positioned to allow continued flow of air through a throttle body and an intake manifold of an air induction system. The valve mechanism is disposed within the exhaust gas recirculation passage and controls the flow of recirculated exhaust gas through the recirculated exhaust gas passage into the airflow passage. The valve mechanism, preferably, comprises a butterfly valve. An electric actuator, which is also integrated into the housing, operates the valve mechanism.
