ABSTRACT:
Apparatus for moving a reciprocating object, such as a spring biased poppet valve, between a rest and a second position. The apparatus includes two solenoids, each of which has a core, with one of the solenoids having a larger core and imparting greater force than the other. The solenoids are mounted in line with one another so that the core of one solenoid is adapted to contract the core of the other, with the latter being adapted to contact the object. A first solenoid provides a driving force to the object to move it in opposition to a biasing force and the second solenoid holds the object in its moved position when the first solenoid is de-energized. When the core of the first solenoid is in its rest position, it is out of contact with the core of the second solenoid and this enables the biasing force of the object to rapidly move to its rest position upon de-energization of the second solenoid.
