Abstract: A filter assembly for filtering hydraulic fluid in a hydraulically actuated fuel injector is disclosed. The filter assembly includes a plurality of first rollers and a plurality of second rollers. The first rollers are parallelly disposed one after the other, and define first axes disposed in a first plane. The second rollers are parallelly disposed one after the other, and define second axes disposed in a second plane. The first plane is parallel to the second plane. Further, each second roller is disposed between a consecutively arranged pair of first rollers to define one or more filtration zones for filtering the hydraulic fluid.

Abstract: Rods for increasing pressure within an oil reservoir of an engine are described. In some embodiments, the rod includes a front end with a front flange and a rear end with a rear flange to assist with centering the rod within the oil cavity. The rod may be comprised of a front section that removably attaches to a rear section via a connector screw and the connector screw may be long enough to prevent the connector screw from backing out when the rod is in the oil cavity. Methods of using and installing the rod are also described.

Abstract: A unit fuel injector (30) has a reverse flow check (122) disposed in a circular reverse flow check cavity (124) to substantially close an exit through-passage (112) to the cavity which has a central axis (125) parallel to and spaced radially from a longitudinal axis (AX) of the unit fuel injector. The exit through-passage opens to the circular reverse flow check cavity at the central axis of the circular reverse flow check cavity. An adjoining cavity (131) distally adjoins the circular reverse flow check cavity. A passage (132) that at the adjoining cavity is radially off-set from the central axis of the circular cavity extends distally to a distal end of the spring cage.

Abstract: A common rail directly actuated fuel injection valve is disclosed with a hydraulic transmission device that is fluidly isolated from the fuel so that the hydraulic fluid can be different from the fuel. This arrangement is particularly suitable for valves that inject a gaseous fuel, but can also be beneficial for use with liquid fuels. According to the method, the hydraulic fluid is pressurizable by the fuel pressure to reduce differential pressures and leakage, in addition to assisting with operation of the hydraulic transmission device. The method further comprises detecting the position of the valve needle for more accurate control of rate of fuel injection during an injection event.

Abstract: A fuel injection system includes a plurality of hydraulically actuated fuel injectors with direct control needle valves. Each injector has an injector body that defines an actuation fluid inlet, a fuel supply passage and a needle control chamber. A needle valve member is movably mounted in the injector body and has a closing hydraulic surface exposed to pressure in the needle control chamber. Each injector also includes a relatively slow moving actuation fluid control valve member and a relatively fast moving needle control valve member. A source of low pressure fluid is connected to the fuel supply passage, and a source of high pressure fluid is connected to the actuation fluid inlet.

Abstract: A control module which controls camless hydraulically driven intake and exhaust valves and an hydraulically driven fuel injector of an internal combustion engine. The module contains a valve assembly to control the intake valve, a valve assembly to control the exhaust valve and a valve assembly to control the fuel injector. The valve assemblies preferably each contain a pair of solenoid actuated two-way spool valves. The solenoids are actuated by digital pulses provided by an electronic assembly within the module. The solenoid actuated spool valves control the flow of a hydraulic fluid to and from the fuel injector and the intake and exhaust valves. The hydraulic fluid opens and closes the intake and exhaust valves. The hydraulic fluid also actuates the fuel injector to eject a fuel into a combustion chamber of the engine. The electronic assembly of each module can be connected to a main microprocessor which provides commands to each assembly. Each electronic assembly processes the command, feedback signals from the hydraulically actuated devices and historical data to insure a desired operation of the fuel injector and intake and exhaust valves.

Abstract: A hydraulically actuated fuel injection system includes an actuation fluid supply pipe having a flange. A hydraulically actuated fuel injector has a centerline, at least two different clamping surfaces and a side surface with an actuation fluid inlet. The clamping surfaces are positioned on opposite sides of the centerline. A clamp is attached to the flange of the actuation fluid supply pipe around the centerline of the injector while bearing against the at least two different clamping surfaces. The clamp allows for reliable sealing in a small space while minimizing internal distortion to injector components.

Abstract: An injection valve arrangement for injecting a pressure medium into a combustion chamber of an internal combustion engine comprises a valve body formed with a feed duct and an actuation chamber, and an elongated valve member fitted in the valve body and movable in the valve body between an open position and a closed position. The valve member is formed with an internal chamber which is in communication with the feed duct and is also formed with one or more nozzle orifices which provide fluid communication between the internal chamber and the combustion chamber when the valve member is in the open position. The valve member has a piston surface bounding the actuation chamber such that force acting on the valve member due to pressure in the actuation chamber urges the valve member toward its open position against the force of a spring. A control valve controls feeding of pressure medium to the actuation chamber, so that when the control valve is open, supply of pressure medium to the actuation chamber causes an increase in pressure in the actuation chamber.
