Abstract: A jet dispenser is provided with a giant magnetostrictive actuator which expands or contracts in response to electric currents. A set of flexural elements is coupled to first and second ends of the giant magnetostrictive actuator and flexes when the giant magnetostrictive actuator expands or contracts. The jet dispenser further comprises a chamber containing fluid and the fluid is dispensable through a nozzle which is in communication with the chamber. A piston coupled to the set of flexural elements is slidably located in the chamber and is actuable by flexion of the flexural elements to apply a force against the fluid for dispensing fluid through the nozzle.

Abstract: A fuel injector-engine component assembly includes an engine component with a stepped bore defined along an axis and having a stepped bore stop surface facing axially upward. A fuel injector extending along the axis is disposed in the stepped bore and includes a fuel injector stop surface facing axially downward and axially opposing the stepped bore stop surface. An isolation ring is disposed between the engine component and fuel injector stop surfaces for axially isolating the fuel injector from the engine component. The isolation ring includes a rigid support member for limiting the axial motion of the engine component and fuel injector stop surfaces together. The isolation ring also includes a resilient and compliant isolation member located axially between the engine component and fuel injector stop surfaces to provide acoustic and thermal isolation between the fuel injector and the engine component below a predetermined pressure of the fuel injector.

Abstract: A fuel injector system comprising a universal fuel injector assembly having a universal electrical receptacle, and a family of specific adaptors for connecting the universal fuel injector assembly to a corresponding family of specific engine harnesses and/or design layouts. The universal fuel injector assembly has an injector tip and fuel rail tip compatible with the engine and fuel rail sockets of a plurality of engines. Each adaptor comprises a fuel-injector plug at a first end for mating with the electrical socket and a harness-specific plug or socket at a second end for mating with a specific harness socket or plug.

Abstract: A flow sensing fuel system for multiple port fuel injection gasoline engines, gasoline direct injection engines, or common rail diesel engines include a flow monitoring device positioned in a fuel flow passage between a fuel pump and a fuel rail, a fuel pressure sensor in fluid communication with said fuel rail, and a controllable pressure regulator closing to a fuel tank. By integrating flow monitoring device, fuel pressure sensor, and controllable pressure regulator in existing fuel systems, a flow sensing fuel system is provided that protects the engine and limits the fuel leaking into the environment in case of a stuck open condition or sealing problem of one or more injectors or in case of a leak in the fuel rail assembly. The flow sensing fuel system enables monitoring the fuel flow during engine start-up, during engine operation, and after engine shut down.

Abstract: An improved O-ring retainer arrangement for retaining an O-ring on a fuel tube of a fuel injector. An overmolded hard plastic ring is disposed on the cylindrical outer surface of the fuel tube. The end of the fuel tube is radially flared to retain the ring on the tube, the radial extent of the flare being less than or equal to the radial thickness of the ring such that the flare cannot come into contact with the bore of a fuel rail socket. The ring is formed such that axial compressive forces exerted on the ring are outside the fuel tube body and preferably are directly opposed, thus exerting no toroidal torque on the ring. The ring is free to move axially on the fuel tube surface. In one aspect of the invention, the ring can move freely along only a limited region on the fuel tube.

Abstract: A fuel injection system includes a fuel injector socket including a first attachment feature and a fuel injector including a second attachment feature that corresponds with the first attachment feature. The first attachment feature engages with the second attachment feature connecting the fuel injector to the fuel injector socket and preventing rotational movement of the fuel injector relative to the fuel injector socket. The corresponding attachment features not only enable simple connection and disconnection of a fuel injector to a fuel injector socket of a fuel rail, but can also be integrated into existing injector to fuel rail assembly processes and are applicable in any fuel injection system. The corresponding attachment features may be used with metal fabricated fuel rail assemblies as well as for fuel rail assemblies where the manifold supply tube and the fuel injector sockets are overmolded with a plastic material.
