Abstract
An electromagnetic actuator for an electromagnetically actuated valve is disclosed. The actuator includes an electromagnet and an armature, the armature having a normally biased initial spaced apart first position distal from the electromagnet when the electromagnet is off and a second fixed stop position in abutment with the electromagnet when the electromagnet is on. In addition, the actuator includes a resilient member adapted to bias the armature in the normally biased initial spaced apart first position, and a compliant member operably connected to the armature. The armature approaches the electromagnet when the electromagnet is on and compresses the compliant member until the armature reaches the fixed stop position.
