Piezo actuator and associated production method

摘要

A support assembly for a piezoelectric actuator (15), in particular for a piezoelectric actuator for driving an injector for the injection system of an internal combustion engine has a holder (5-10) for spatially securing a piezoelectric stack (2) and two associated connection pins (11, 12) for electrically contacting the stack (2). The support assembly is configured as a single support, which only holds a single piezoelectric stack (2) with two associated connection pins (11, 12).
