Abstract: The present disclosure describes an injector for an internal combustion engine which includes an injector housing, a piezo-actuator control unit having a first set of terminals, a connecting plug on a head of the injector housing, the connecting plug having a second set of terminals, and an electrical connection between the control unit and the connecting plug within the injector housing. The electrical connection comprises a contact element with conductor tracks integrated into an insulating body. The conductor tracks are connected to the terminals of the control unit and of the connecting plug. A first end of the insulating body abuts the control unit or the connecting plug and a second end is spaced from the connecting plug or the control unit. The contact element includes an elastic device by means of which the insulating body is braced against the component it abuts.

Abstract: The invention relates to a retractor (10) with a carrier ring (20) and L-shaped valves (30), which can be attached with an arm (32) which runs parallel to the carrier ring plane to the carrier ring (20), whereby its free end points outward, and whose other arm (34) is oriented perpendicularly with a respect to the carrier ring plane and presents, in cross section, a convex curvature toward the external margin of the carrier ring (20), where the arm of (32) [sic; arm (32)] of the valves (30), which is attached to the carrier ring (20), is guided in radically oriented guides (22) on the carrier ring (20).
