METHOD OF ASSEMBLING AN ACTUATOR ARRANGEMENT |
摘要 |
<p>A method of assembling a piezoelectric actuator arrangement comprises providing a piezoelectric element having first and second ends and arranging the piezoelectric element within a sleeve member such that the inner surface of the sleeve member defines, together with the outer surface of the piezoelectric element, a chamber for receiving a first filler material. The first filler material is injected into the chamber and a heating effect is applied to the sleeve member such that the sleeve member deforms to seal against the first filler material. The invention also relates to a piezoelectric actuator arrangement arranged within a sleeve member, an inner surface of the sleeve member and an outer surface of the piezoelectric element together defining, at least in part, a chamber containing a filler material such that, when the actuator arrangement is in use, a force due to fuel pressure within an injector accumulator volume is applied to the piezoelectric element through the sleeve member and the filler material.</p> |
