Abstract
A booster actuator may be positioned between the solenoid and a valve , and increases the energy output from the solenoid to activate the valve. The booster actuator may include a force input member and a force output member each linearly movable with respect to a body from an initial position to an activated position. A coil spring biases the input member to the initial input position, while a plurality of disk springs bias the output member to the activated output position. A plurality of linking members each pivotable with respect to the body normally retain the force output member in the initial position, but upon movement of the input member to the activated position release the force output member in response to the disk springs.
