<p>The control drive has a piezoelectric actuator (2) and a housing (25) enclosing the actuator. A sound-absorbing cover (7) is mounted on the control drive in vibration decoupled manner. The cover has an inner coating (71) of a sound-damping material. The sound-absorbing cover sits on rubber rings (81,82) in grooves (41,14) in an actuator connection (4) and an injector head housing (1).</p> |
