摘要：A method of assembling a piezoelectric actuator arrangement () comprises thesteps of providing a piezoelectric element () having first and second ends and arranging

the piezoelectric element () within a sleeve member () such that the inner surface of thesleeve 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 intothe chamber () and a heating effect is applied to the sleeve member () such that thesleeve member () deforms to seal against the first filler material (). The invention alsorelates to a piezoelectric actuator arrangement () arranged within a sleeve member (), aninner 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 injectoraccumulator volume is applied to the piezoelectric element () through the sleevemember () and the filler material ().
