ABSTRACT:
A variable force actuator with a double needle poppet assembly includes a housing in which a first poppet and a second poppet are slidably disposed. The second poppet fits within the first poppet, and both poppets move when a nearby coil is energized to establish, in combination, a fluid flow configuration in response to the amount of energy applied to the coil.
