Abstract (en)
An injector for internal-combustion engines, comprising: a base body (12) having a valve seat (20); a needle element (22) which can slide inside the base body (12) and is designed to open and close the aforesaid valve seat; and an actuator device which is designed to control sliding of said needle element (22). The piezoelectric actuator (28) is an amplified piezoelectric actuator having a bar (30) made of piezoelectric material, which co-operates with an amplifying structure (32). The bar (30) of piezoelectric material is set orthogonally to the direction of sliding of said needle element (22). <IMAGE>
