Abstract: A fuel injector includes a nozzle having at least one first orifice. The at least one first orifice selectively injects a first fuel. An outer check is located movably within the nozzle. The outer check includes at least one second orifice. The at least one second orifice selectively injects a second fuel. An inner check is located movably and concentrically within the outer check. The at least one first orifice is adapted to selectively inject at least one of the first fuel and the second fuel therethrough based on a position of each of the outer check and the inner check.

Abstract: A fuel injector includes a nozzle having at least one first orifice provided therein. The at least one first orifice is adapted to selectively inject one of a fuel and an oxidant. An outer check is disposed movably within the nozzle. The outer check includes at least one second orifice provided therein. The at least one second orifice is adapted to selectively inject an other of the oxidant and the fuel. An inner check is disposed movably and concentrically within the outer chock. The at least one second orifice is adapted to align with respect to the at least one first orifice to selectively inject the fuel and the oxidant together through the at least one first orifice based on a position of each of the outer check and the inner check.

Abstract: A liquid fuel injector such as for a dual fuel system in an internal combustion engine includes two-way injection control valves for controlling twin outlet checks. A first set of orifices are arranged in an A-F-Z pattern, and a second set of orifices are arranged in an A-F-Z pattern, within the fuel injector, among a high-pressure inlet passage, a low-pressure space, and first and second outlet check control chambers, respectively. A common nozzle supply cavity is fluidly connected to the high-pressure inlet passage and supplies each of two sets of nozzle outlets opened and closed by the twin outlet checks.

Abstract: A fuel injector includes a nozzle including at least one outer orifice. The at least one outer orifice selectively injects a first fuel. An outer check is disposed movably within the nozzle. The outer check includes at least one first orifice and at least one second orifice. The at least one first orifice and the at least one second orifice are disposed circumferentially spaced apart with respect to one another. Each of the at least one first orifice and the at least one second orifice selectively injects a second fuel. An inner check is disposed movably and concentrically within the outer check. The at least one outer orifice is adapted to selectively injects at least one of the first fuel and the second fuel therethrough based on a position of each of the outer check and the inner check.

Abstract: A bearing arrangement for a wobble plate piston pump includes first, second, third, and fourth bearing assemblies. The first and second bearing assemblies support the drive shaft portion for rotation within the housing about the central longitudinal axis, while the third and fourth bearing assemblies support the load plate for rotation relative to the offset shaft portion of the shaft. The second bearing assembly is distally disposed from the first, the third disposed distally to second, and the fourth disposed distally to third. The fourth bearing assembly is the most distally disposed bearing assembly along the shaft.

Abstract: A pump for pumping a cryogenic fluid includes an activation portion that includes at least one actuator. The activation portion contains oil that may be cooled by the cryogenic fluid. The pump further includes a pumping portion that includes at least one pumping element, the at least one pumping element being operated by the at least one actuator, and a heater associated with the activation portion and configured to, when the heater is active, transfer heat energy to the activation portion such that the oil contained in the activation portion is warmed.
