  • Publication number: 20240200583
    Abstract: A dual orifice component has a plug with a unitary body that defines a central axis and has opposite axial ends. First and second holes are aligned along the central axis and each has first and second axially opposite ends. A third hole extends perpendicular to the central axis and passes through the plug. The first end of the first axial hole is located at one axial end of the plug, and the second end of the first axial hole communicates with and is open to the third hole. The first end of the second axial hole is located at the other axial end of the plug, and the second end of the second axial hole communicates with and is open to the third hole such that the first and the second holes are axially separated from each other by the third hole.

  • Publication number: 20230311834
    Abstract: An improved electrohydraulic brake valve with overpressure protection is provided. The electrohydraulic brake valve includes an integrated pressure limiting device coupled to a modulating valve and a solenoid assembly. The pressure limiting device transmits an axial force from the solenoid plunger to the valve spool up to a set limit, which corresponds to a maximum output pressure. Above this set limit, a pre-loaded spring within the pressure limiting device compresses, thereby isolating further travel of the solenoid plunger from the valve spool. The pressure limiting device mechanically limits the output pressure of the electrohydraulic brake valve to a maximum level to prevent overpressure in the brake system, adding a level of safety not previously available.

  • Publication number: 20210164585
    Abstract: A valve assembly is provided. The valve assembly includes a valve body defining a bore. The valve assembly further includes a plunger adjacent the valve body. The valve assembly further includes a modulating biasing member abutting the plunger. The valve assembly further includes a spool disposed in the bore and adjacent the plunger with the modulating biasing member disposed therebetween. The plunger is configured to move the spool between a neutral position and an energized position. The spool defines a socket. The valve assembly further includes a piston disposed in the socket and configured to move between a first piston position and a second piston position within the socket.

  • Publication number: 20210165431
    Abstract: A valve assembly is provided. The valve assembly includes a valve body defining a bore. The valve assembly further includes a pull rod disposed in the bore and defining a bolt cavity. The pull rod is moveable between a first pull rod position and a second pull rod position. The valve assembly further includes a bolt disposed in the bolt cavity and moveable with respect to the pull rod between a first bolt position and a second bolt position. The valve assembly further includes a spool disposed in the bore. The spool is operatively coupled to the pull rod to move between an energized position and a neutral position.
