Patent number: 7201136Abstract: A fuel delivery injector for an internal combustion engine is provided. A fuel injector forms part of a device which provides a combined injection and ignition. The fuel delivery injector comprises first and second portions adapted to be detachably connected together. The first portion incorporates a valve structure having a valve member movable with respect to a valve seat for opening and closing a delivery port, and an actuating member operatively connected to the valve member. An actuator is provided in the second portion. When the first and second portions are connected together, the actuator is operably associated with the actuating member to provide an actuating assembly. Typically, the actuating assembly comprises an electromagnetic device in which the actuating member comprises a solenoid armature and the actuator comprises a solenoid coil, whereby connection of the first and second portions together completes assembly of the electromagnetic device.Type: GrantFiled: April 18, 2002Date of Patent: April 10, 2007Assignee: Orbital Engine Company (Australia) Pty LimitedInventors: Michael Leonard McKay, David John Longman, James Allen Kimmel

Patent number: 7086376Abstract: A device (10) providing a combined fuel injection and ignition means for a spark-ignition internal combustion engine. The device (10) comprises a insulator body (25) of ceramic material, a fuel flow path (24) having a section thereof encased in the insulator body (25) and terminating at a delivery port (45) disposed outwardly of the insulator body (25), and, an ignition path (23) having a section encased in the insulator body (25) in a spaced apart relationship with respect to the section of the fuel path (24). The fuel path (24) is defined within a valve structure (33) detachably secured to the insulator body (25) so as to be selectively removable therefrom. The ignition path (23) terminates at an electrode (95) disposed outwardly of the insulator body (25). The insulator body has a nose portion (100) and a skirt portion (69) beyond the delivery port (45).Type: GrantFiled: February 28, 2001Date of Patent: August 8, 2006Assignee: Orbital Engine Company (Australia) PTY LimitedInventor: Michael Leonard McKay

Patent number: 6755175Abstract: A fuel delivery injector for a spark-ignition internal combustion engine. The delivery injector forms part of a device (10) which provides a combined fuel injection and ignition means for the engine. The fuel delivery injector comprises means defining a flow path (28) for delivery of a fuel entrained in a gas to a combustion chamber of the engine. The flow path (28) has a delivery port (30) through which the fuel is delivered into the combustion chamber as a spray of fuel droplets and vapour, the delivery port (30) being defined between a valve seat (31) and a valve member (23) movable with respect to the valve seat (31) for opening and closing the delivery port (30). The delivery injector is configured to influence the trajectory of the fuel spray, whereby smaller fuel droplets and vapour in the fuel spray are caused to flow towards a spark gap (49) in close proximity to the downstream end of the delivery port (30) and whereby larger fuel droplets are not so caused to flow towards the spark gap (49).Type: GrantFiled: May 28, 2002Date of Patent: June 29, 2004Assignee: Orbital Engine Company (Australia) Pty LimitedInventors: Michael Leonard McKay, Mark Douglas Archer

Patent number: 6463916Abstract: A fuel injector assembly for an internal combustion engine, including: a delivery chamber (5) located within the injector assembly (1); a mass flow rate control means (50) for controlling the mass flow rate of fuel and compressed gas supplied to the delivery chamber (5), the mass flow rate being a function of the differential pressure across the mass flow rate control means (50); and valve means (9) for selectively communicating the delivery chamber (5) to the engine to deliver fuel to the engine; wherein when the valve means (9) is opened, at least compressed gas is caused to flow thereby generating a differential pressure across the mass flow rate control means such that a controlled fuel flow is provided to the engine.Type: GrantFiled: December 6, 2000Date of Patent: October 15, 2002Assignee: Orbital Engine Company (Australia) Pty LimitedInventors: Nicholas Coplin, Raymond John Hill, Michael Leonard McKay

Patent number: 6439863Abstract: A fuel pump designed to prevent vapor lock. The pump comprises an inlet check valve located between a pumping chamber and a reservoir. The inlet check valve allows the flow of fluid from the reservoir into the pumping chamber. The inlet check valve is constructed such that when a combination of both liquid and vapor is present in the pumping chamber, the liquid and vapor is allowed to flow from the pumping chamber back into the reservoir; but when the pumping chamber is filled only with liquid, the inlet check valve prohibits flow from the pumping chamber into the reservoir.Type: GrantFiled: January 23, 2001Date of Patent: August 27, 2002Assignee: Orbital Engine Company (Australia) Pty. LimitedInventor: Michael Leonard McKay

Patent number: 6095769Abstract: A pump including a first enclosure (10) and a second enclosure (20), a pumping mechanism (3) and an electromotive means (11,23) operable to drive the pumping mechanism (3). The electromotive means (11,23) includes a solenoid assembly (11) having a solenoid coil (13), and an armature assembly (23), the solenoid coil (13) being sealed within the first enclosure (10). The pump mechanism (3) is supported within the second enclosure (20), the armature assembly (23) being in operational relationship with the pumping mechanism (3). A diagnostic sensor (19) is sealed within the first enclosure (10) for detecting flow through a flow path (22) in the second enclosure (20). A flow responsive member (28) is supported within the flow path (22), the diagnostic sensor (19) detecting displacement of the flow responsive member (28).Type: GrantFiled: September 27, 1996Date of Patent: August 1, 2000Assignee: Orbital Engine co. (Australia) Pty LimitedInventor: Michael Leonard McKay

Patent number: 5904126Abstract: A control system and method for controlling a pump having a fluid passage therein, including a sensing means for sensing fluid flow through the fluid passage wherein the control system controls the actuation period of the pump as a function of a characteristic of the fluid flow sensed by the sensing means. The sensed characteristic is the quantum rate of fluid flow through the fluid passage.Type: GrantFiled: September 27, 1996Date of Patent: May 18, 1999Assignee: Orbital Engine Company (Australia) Pty LimitedInventors: Michael Leonard McKay, David Shawcross, Craig Bowman, Thomas Schnepple
