Abstract
A direct drive electromagnetic actuator includes a housing and a movable body extended by an actuating head. A resilient member exerts a force on the movable body toward an inoperative position. A coil interacts with the movable body so as to generate a second force on the movable body toward an operative position. The actuator further includes a shock-absorbing block movable with respect to the housing over at least a portion of the travel of the movable body and joined to the resilient member. The shock-absorbing block is compressed when the movable body is in the operative position. The actuator also includes a rigid abutment movable over at least a portion of the travel of the movable body between the inoperative position and the operative position, the rigid abutment coming into contact with a wall secured to the housing when the movable body is in the operative position.
