Abstract: A control valve assembly for controlling fuel pressure in a control chamber of a fuel injector. The control valve assembly comprising a valve member arranged in a bore provided in a valve housing, at least one of the valve member and the valve housing being moveable with respect to the other, wherein the valve member comprises a fuel-receiving cavity arranged to receive fuel that distorts at least a portion of the valve member so as to increase an external dimension thereof.

Abstract: A fuel injector for an internal combustion engine includes an injector body in which there are positioned an actuator, a control valve, and a needle guide. The actuator actuates the control valve, the control valve controlling an injection needle sliding the needle guide between an open position in which injection is permitted and a closed position in which the injection of fuel is prevented. The injector additionally includes a first electrical connection extending from the needle guide to a metal that are internal to the injector, and a metal extension extending from the metal ring to a connector pin accessible from the outside of the injector, so that an electrical signal indicative of the position of the needle can be transmitted from the needle guide for the needle to the connector pin.

Abstract: A fuel injector comprising a valve needle slidable within a bore, a surface associated with the valve needle being exposed to the fuel pressure within a control chamber and an electromagnetically actuable control valve controlling communication between the control chamber and a low pressure chamber. The injector also comprises a damping arrangement arranged to damp pressure waves applied to the low pressure chamber.

Abstract: An electric resistance element (1) in a device for deicing a wing structure such as the wing of an aircraft or the blades of a helicopter, which includes conducting fibers embedded in a composite fiber structure and power supply wires connected electrically to said conducting fibers. In this element, the conducting fibers are carbon fibers in the form of at least one ribbon (2) in which the fibers are oriented longitudinally, preimpregnated with resin and at least one end of which is fixed in a deformable tubular metal mesh element (3) providing the electric connection by contact with the ribbon and which in turn is soldered to the corresponding power supply wire (4).
