Piezoelectric actuator module for fuel injection valve i.e. injector, for fuel injection system of air-compressed, self-striking internal combustion engine, has electrode connection connected with electrical supply line via contact bridge

摘要

The module (2) has an actuator body (10) including an electrode connection (11) lying outside the actuator body. The electrode connection is connected with an electrical supply line (20). A contact bridge (18) is clamped to the actuator body. The contact bridge contacts the electrode connection in an active region (22) of the actuator body. The electrode connection is connected with the electrical supply line via the contact bridge. The contact bridge is coated with a copper coating, and elastically deformable in a sectional manner. An independent claim is also included for a fuel injection valve i.e. injector, for a fuel injection system of an air-compressed, self-striking internal combustion engine.
