    摘要： A damping assembly for a valve is provided. The valve is configured to move between an open position and a close position. The valve includes a valve element and a valve stem disposed within a head. The damping assembly includes a damping chamber defined within the head. The damping assembly defines a sidewall. The damping assembly also includes a collar configured to receive the valve stem. The collar includes a collar stem. The collar also includes a collar head having an outer diameter. The collar head includes a side surface. The damping assembly includes a liquid passageway. The liquid passageway is being defined by a radial clearance between the side surface of the collar head and the sidewall of the damping chamber. The liquid passageway is configured to control a flow of a liquid as the valve moves between the open position and the closed position.

    摘要： The present disclosure is related to a flow limiting system for a dual fuel engine is disclosed. The flow limiting system includes a first valve configured to regulate a flow of a liquid fuel therethrough based on a pressure difference across the first valve. The flow limiting system further includes a second valve configured to regulate a flow of a gaseous fuel therethrough based on a pressure difference across the second valve. The second valve includes a valve body movably provided within a valve chamber. The valve body includes a control orifice extending therethrough. The valve body also includes grooves defined on an outer surface thereof.

    摘要： A fluid injection system includes a fluid injector assembly; a fluid conditioning module having an outlet port that is fluidly coupled to an inlet port of the fluid injector assembly; an injector assembly outlet conduit fluidly coupled to an outlet port of the fluid injector assembly and disposed downstream of the fluid injector assembly, the injector assembly outlet conduit defining a pressure measurement port and a flow-restricting orifice, the pressure measurement port being disposed upstream of the flow-restricting orifice along the direction of fluid flow through the fluid injector assembly; a pressure sensor fluidly coupled to the pressure measurement port; and a controller operatively coupled to the fluid conditioning module and the pressure sensor. The controller is configured to adjust a flowrate of a fluid through the injector assembly inlet conduit based on a pressure signal from the pressure sensor.
