<p>A piezo actuator in the form of a piezo injector, includes a holding body having an inner space, and having a piezo element disposed in an inner space and encompassing multiple piezoelectric plies disposed to form a stack, which element is electrically contactable through the holding body. The holding body has one or more connectors for electrical contacting of the piezo element, as well as one or more connectors and flow conduits for delivering into the inner space a fluid that can be metered by way of an adjusting member encompassing the piezo element, such that in the piezo actuator, the flow conduit connecting the inner space and the connector for the fluid is offset radially outward with respect to the electrical conductors leading through the holding body and substantially constituting the electrical contact system, and is disposed to extend substantially parallel to said conductors; and a plug connection connecting the piezo element to the electrical conductors is disposed between the holding body and piezo element.</p> |
