  • Valve assembly with electronic control
    Patent number: 10330205
    Abstract: A valve assembly includes a housing (22) that has a fluid input (24) and a fluid output (26). A pintle (30) is disposed in the housing, and an actuator (36) is operatively coupled to move the pintle. The pintle includes a passage (32) that fluidly couples the fluid output with a pressure balance volume (34) located between the pintle and the housing adjacent the linear actuator. A controller (38) is electrically connected with the actuator, and there is a variable flow area (40) from the fluid input to the fluid output that is defined between the pintle and the housing.
