摘要:
A reception bush for a piezoelectric actuator is provided with two connection pins for electrically bonding the piezoelectric actuator, in particular for a piezoelectric actuator controlling the injector of an injection system for an internal combustion engine. The reception bush has a first (1) and a second (2) bush elements which are interconnected when the bush is mounted. The first element (1) is provided with through holes (4, 5) for the connection pins of the inventive piezoelectric actuator. The second element (2) is provided with at least one guide (12) for the connection pins.

The invention relates to a receiving sleeve for a piezoelectric actuator, in particular for a piezoelectric actuator for driving an injector of an injection system in an internal combustion engine. Said sleeve comprises a first sleeve part (1) and a second sleeve part (2), the first sleeve part (1) being connected to the second sleeve part (2) when the sleeve is assembled. In addition, the inventive receiving sleeve comprises an anti-rotation element (6, 8) for maintaining a predefined angular position between the first sleeve part (1) and the second sleeve part (2).

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).
摘要:
A receiving sleeve (1) for an actuator body, in particular for holding a piezoelectric stack of a piezoelectric actuator, is used to drive an injector of an injection system for an internal combustion engine. The sleeve is equipped with at least one spring element (10, 11) for centering the actuator body in the receiving sleeve (1) and/or for compensating component tolerances of the actuator body.
