Abstract: A valve assembly for a fuel pump is provided. The valve assembly may include an inlet valve limited to a first range of travel extending between a fully closed position and a fully opened position of the inlet valve, a valve pin coupled to the inlet valve, an armature pin selectively engaging the valve pin, and an armature coupled to the armature pin and limited to a second range of travel extending between an engaged position and a disengaged position that is less than the first range of travel.

Abstract: A fuel injector has the ability to inject two fuels that differ in at least one of pressure, chemical identity and matter phase, such as liquid diesel fuel and nature gas. A first direct operated check includes a closing hydraulic surface exposed to fluid pressure in a first control chamber, and is normally biased toward a closed position by a first spring. A second direct operated check has a closing hydraulic surface exposed to fluid pressure in a second control chamber, and is biased toward a closed position with a second spring. The first spring and the second spring are located on opposite sides of a plane oriented perpendicular to a long axis of the injector body, in part to satisfy packaging constraints when the direct operated checks are arranged in a side by side parallel configuration.

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 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 pump is disclosed having a manifold with an inlet, a pressure outlet, and a return outlet. The pump may also have a jacket connected to an end of the manifold to create an enclosure that is in fluid communication with the inlet of the manifold, and at least one pumping mechanism extending from the manifold into the jacket. The at least one pumping mechanism may have an inlet open to the enclosure and an outlet in communication with the pressure outlet of the manifold. The pump may further have a standpipe extending from the manifold into the enclosure. The standpipe may be in communication with the return outlet of the manifold.
