ABSTRACT:
A linear expansion or contraction of a piezoelectric element (150) is converted into a corresponding magnified linear movement of an output member (120) along a central axis (34) by a series combination of a pair of magnifying lever arms (100, 102) supported from a retainer structure (52) via a pair of elastic integral hinges (96, 98) and a pair of links (110, 112; 206, 208) wherein the retainer structure is enclosed in a housing (38) and adjustably fastened thereto so as to be adjustably shiftable relative thereto along the central axis.
