Kind Code:
A
Abstract:
The invention relates to a piezoelectric actuator in particular for actuating control valves or injection valves in internal combustion engines in motor vehicles, having a piezoelectric actuator body, in particular in the form of a multilayer laminate of stacked layers of piezoelectric material and intervening metal or electrically conductive layers acting as electrodes, in which one of the face ends of the actuator body is fixed on a highly heat-conducting or metal actuator base, in which the piezoelectric actuator includes at least one highly heat-conductive cooling body joined highly heat-conductingly to the side faces of the actuator body and to the actuator base.
