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 fuel injector is disclosed. The fuel injector may have an injector body having a fuel inlet and at least one orifice. The fuel injector may also have a first check valve member. The first check valve member may be selectively movable to fluidly block a first flow of fuel from the fuel inlet to the at least one orifice. The fuel injector may have a second check valve member. The second check valve member may be selectively movable to fluidly block a second flow of fuel from the fuel inlet to the at least one orifice. The fuel injector may also have a control valve assembly. The control valve assembly may be configured to selectively operate either the first check valve or both the first check valve and the second check valve to fluidly connect the fuel inlet and the at least one orifice.

Abstract: A fuel injector system includes an injector body having a proximal end and a distal end, the injector body defining a nozzle having an outlet. The injector system includes a spill valve fluidly connected to the outlet and having a spill valve member movable between an open position and a closed position. The injector system includes a control valve including a control valve member movable between an open position and a closed position. The injector system includes a check valve fluidly connected to the outlet, the control valve including a check valve needle movable between an open position and a closed position. The injector system also includes an electrical monitoring circuit configured to output a signal indicative of at least one of the open position or the closed position of the spill valve member.

Abstract: A cryogenic fluid pump includes a plurality of pumping elements, each of the plurality of pumping elements having an actuator portion that is associated with and configured to selectively activate one end of a pushrod in response to a command by an electronic controller, an activation portion associated with an opposite end of the pushrod, and a pumping portion associated with the activation portion. For each of the plurality of pumping elements, the pumping portion is activated for pumping a fluid by the activation portion, which activation portion is activated by the actuator portion. The electronic controller is configured to selectively activate each of the plurality of pumping elements such that a flow of fluid from the cryogenic fluid pump results from continuous activations of the plurality of pumping elements at selected dwell times between activations of successive pumping elements.

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 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.
