Abstract

Improvement in the isolation of a stack of piezoelectric discs having conductive planar surfaces, discs that are arranged in series in a stack, and in which a voltage is applied to the opposite surfaces of said discs to make said stack expand axially, an improved arrangement for isolating the radial edges of said piezo disks it comprises.
