Abstract: System and methods for controlling a flow of fluid in a fuel system are disclosed. In an aspect, a gas admission system includes a gas admission valve assembly having an inlet, an outlet, and a valve configured to control a flow of fluid between the inlet and the outlet and a flow limiter assembly in fluid communication with the inlet of the gas admission valve assembly.

Abstract: A pressurized fuel system for an engine includes a fuel pump in a pump protection device structured to drain pressurized fuel from a common rail to provide fuel flow through the fuel pump that limits cavitation. The device includes a valve mechanism having a first valve and a second valve that are movable to an open position and a closed position respectively, in response to valve opening and valve closing rail pressures. The active pressure range of the device may be a medium pressure range.

Abstract: A fuel pump system configured to control a pressure pulse within a fuel system. The fuel pump system includes a conduit and a pump fluidly coupled to the conduit. The conduit has a conduit volume and is configured to contain fuel within. The pump includes a first pump stage in which the pump defines a maximum pump displacement and a second pump stage in which the pump defines a minimum pump displacement. The pump is configured to provide an output mass of fuel to the conduit when the pump transitions from the first pump stage to the second pump stage, causing pressure of the fuel within the conduit to pulse. The maximum pump displacement is set to a value defined by a ratio of the output mass of fuel per the conduit volume needed to maintain the pressure pulse in the conduit within a predetermined pressure pulse range.
Abstract translation: 一种配置成控制燃料系统内的压力脉冲的燃料泵系统。 燃料泵系统包括导管和流体地联接到导管的泵。 导管具有导管容积并被构造成在其内容纳燃料。 泵包括第一泵级，其中泵限定最大泵排量，第二泵级定义泵的最小位移。 泵被配置成当泵从第一泵级从第一泵级转变到第二泵级时，向管道提供输出质量的燃料，从而导致管道内的燃料的压力脉动。 最大泵排量被设定为由将管道内的压力脉冲维持在预定压力脉冲范围内所需的导管容积的输出质量比的比值定义的值。

Abstract: A fluid system such as a fuel system includes a fluid supply and a pump coupled between the fluid supply and a plurality of fluid delivery devices. The pump can be a cryogenic pump such as for liquefied natural gas, with valve mechanisms to control hydraulic actuation of a piston used to pump the liquefied natural gas. An electrically conductive coil is coupled with the piston. Related methodology is disclosed.
