  • Solenoid valve assembly with configurable solenoid connection
    Patent number: 12292134
    Abstract: A valve assembly includes a valve body that houses valve components for controlling a flow of fluid through the valve body, and a solenoid component that controls operation of the valve components. The solenoid component includes a connector cap that is attached to a solenoid base, the connector cap having a plurality of electrical connection openings oriented at different directions that are configurable at multiple orientations corresponding to different directions connection paths with the solenoid component. The solenoid component is rotatable about a longitudinal axis relative to the valve body to configure the electrical connection openings at one of multiple first orientations corresponding to a rotational position of the solenoid component relative to the valve body.
    Type: Grant

  • Proportional valve spool with linear flow gain
    Patent number: 11680649
    Abstract: An example spool includes a shaft varying in diameter along a length of the shaft, and a plurality of annular lands formed on the shaft and spaced-apart by respective reduced diameter annular neck portions. The plurality of annular lands comprise at least one annular metering land, and wherein the at least one annular metering land comprises: one or more sine notches formed as a portion of a sine wave, and one or more additional notches having a different shape from the one or more sine notches.
