A booster actuator (10) may be positioned between the solenoid (12) and a valve (14), and increases the energy output from the solenoid to activate the valve. The booster actuator (10) may include a force input member (28) and a force output member (30) each linearly movable with respect to a body (20) from an initial position to an activated position. A coil spring (46) biases the input member to the initial input position, while a plurality of disk springs (48) bias the output member (30) to the activated output position. A plurality of linking members (32) 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.

L'invention concerne un actionneur d'appoint (10) qui peut être placé entre le solénoïde (12) et une soupape (14) pour augmenter le rendement énergétique du solénoïde destiné à activer la soupape. L'actionneur d'appoint (10) de l'invention peut comprendre un élément d'entrée de force (28) et un élément de sortie de force (30) pouvant être déplacés chacun relativement à un corps (20) d'une position initiale à une position activée. Un ressort hélicoïdal (46) force l'élément d'entrée à occuper une position d'entrée initiale, tandis que plusieurs ressorts de disques (48) forcent l'élément de sortie (30) à occuper la position de sortie activée. Plusieurs éléments de liaison (32) pouvant tourner chacun relativement au corps retiennent normalement l'élément de sortie de force dans la position initiale mais le libèrent en réaction aux ressorts de disques lorsque l'élément d'entrée accomplit un mouvement vers la position activée.
