Abstract

1525248 Piezoelectric motor devices PHYSICS INTERNATIONAL CO 2 Oct 1975 [3 Oct 1974] 40433/75 Heading H2A [Also in Division F1] In apparatus wherein a piezoelectric element stack 10-18 is surrounded and contacted by a dielectric medium, and wherein a voltage is applied to the stack to generate a motor force, the dielectric medium is pressurized to ensure that the maximum particle velocity of the dielectric medium is greater than the particle velocity of the piezoelectric material; cavitation between the dielectric and piezoelectric materials is therefore prevented and are-over between the materials consequently avoided. The dielectric may be either in fluid or solid form. In the arrangement shown the stack 10-18 moves a diaphragm 22 to pump fluid from a pipe 33 to a pipe 35.
