Actuator with amplified stroke length

An actuator having a housing that defines an interior volume and a primary driver that includes either a piezoelectric element or a magnetorestrictive element. The primary driver has first and second opposing ends and defines a longitudinal length therebetween. The first end of the primary driver is...

description An actuator having a housing that defines an interior volume and a primary driver that includes either a piezoelectric element or a magnetorestrictive element. The primary driver has first and second opposing ends and defines a longitudinal length therebetween. The first end of the primary driver is bearingly engaged with a reaction surface that is fixed relative to the housing. The second end of the primary driver longitudinally moves a bearing surface that partially defines a closed working chamber having a fixed quantity of an incompressible medium. An actuating rod extends through an orifice in the housing and has a first end projecting outwardly and a second end disposed within the working chamber. The cross sectional area of the orifice is less than the effective area of the bearing surface whereby the travel distance of the rod is amplified relative to the change in length of the primary driver.
