Abstract: A fuel injector includes an injector body and a valve stack within the injector body that includes a valve seat plate. The valve seat plate includes a pressure control passage for controlling fuel injection, and a valve seat positioned fluidly between the pressure control passage and a low-pressure drain. The valve seat plate includes a pressure-limiting annular groove that extends circumferentially around the valve seat and axially inward from a side of the valve seat plate where the valve seat is located. The groove enables deformation in response to pressure differences across the valve seat plate in a manner that limits stress concentrations.

Abstract: A fuel system is disclosed for use with an engine, including a fuel injector assembly fluidly coupled with a low-pressure fuel conduit, an accumulator, and a cap within an opening in the accumulator. The fuel injector assembly may be structured to draw in low-pressure fuel, pressurize the fuel, and store the pressurized fuel in the accumulator for injection to a combustion chamber. The cap has a pressure sensor and a pressure relief valve therein, and drains fuel leaked past fluid seals between the cap and each of the pressure sensor, the pressure relief valve, and the accumulator by way of a common drain line.

Abstract: A cryogenic pump for pumping liquefied natural gas (LNG) from a cryogenic tank storing LNG includes a drive assembly and a pump assembly disposed along a pump axis. The drive assembly includes a spool housing having a plurality of spool valves arranged around the pump axis, a tappet housing having a plurality of tappet bores with slidable tappets arranged around the pump axis, and spring housing including a plurality of movably disposed pushrods urged upward by a plurality of associated pushrod springs. Hydraulic fluid received by a hydraulic fluid inlet in the drive assembly is directed by the spool valves to the tappet bores to move the tappets downward against the pushrods. To collect the hydraulic fluid, the lowermost spring housing also includes a collection cavity formed therein that can return the hydraulic fluid to a hydraulic fluid outlet.

Abstract: A method for controlling a stroke velocity in a pump includes using a sensor to detect a start of a pump stroke and an end of the pump stroke. A stroke time is calculated, the stroke time being a time period between the start of the pump stroke and the end of the pump stroke. The stroke velocity is calculated based on a stroke length and the stroke time. The stroke velocity is compared to a reference stroke velocity. A hydraulic supply pressure to the pump is increased if the calculated stroke velocity is less than the reference stroke velocity, and the hydraulic supply pressure is decreased if the calculated stroke velocity is more than the reference stroke velocity.

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.
