  • Publication number: 20210001719
    Abstract: A power take-off includes an input mechanism having an input gear that is rotatably supported on a housing of the power take-off portion. The input mechanism also has a portion that extends outwardly through the opening provided through the mounting surface of the housing of the power take-off portion and that is adapted to extend within and be rotatably driven by the source of rotational energy. The power take-off further includes an output mechanism that is disposed within the housing and includes a driven gear that is rotatably driven by the input gear of the input mechanism. A rotational axis of the input gear and a rotational axis of the driven gear are misaligned so as to minimize the transmission of torque transients and other vibrations therethrough during operation.

  • Patent number: 10871239
    Abstract: A proportional valve includes an actuator, having a first magnet element and a second magnet element that are energized by wire coils; a non-magnetic carrier in which the first magnet element and the second magnet element are mounted; a first spring beam to which the non-magnetic carrier is suspended adjacent to the first magnet element, and a second spring beam to which the non-magnetic carrier is suspended adjacent to the second magnet element; and a flux frame that conducts magnetic field lines through the actuator. When the wire coils are energized, a magnetic field is created which causes the non-magnetic carrier to move against a valve operator to move a valve poppet away from the closed position against a valve seat, thereby opening the valve. The first and second spring beams restrain the movement of the non-magnetic carrier to an arc of sufficient radius that said movement is quasi-linear.

  • Patent number: 10870320
    Abstract: A novel valve that may include a self-energizing seal member with a lobe extending toward a valve seat surface, a radially outwardly extending skirt, an axially extending nose, solenoid-operated three-position valve member, a pressure sense port, and/or a pressure pick-up opening. The features of the valve may allow the valve to operate at higher flow rates while requiring less energy to operate, may have a wider pressure and/or temperature operation range, may allow bidirectional fluid flow, may be less expensive to manufacture, and/or may enable a simple and compact assembly of the valve with a pressure sensor. The self-energizing seal member may include a base portion and the lobe extending may extend at an angle from the base portion relative to a longitudinal axis. The lobe may reduce energy requirements to operate the valve compared to larger sealing contact area seals. For example, the lobe may have a small sealing area to allow the valve to be better balanced.

  • Patent number: 10819252
    Abstract: A device, system and method for harvesting electrical power from hydraulic fluid of a hydraulic system determines at least one of hydraulic fluid flow or hydraulic fluid pressure in the hydraulic system. Based on rules and the determined at least one of the hydraulic fluid flow or hydraulic fluid pressure, an expected conversion efficiency of the power conversion device and an expected rectified power to be generated from the received input power by the power conversion device are determined. From the expected rectified power a potential conversion efficiency of the power conversion device is determined, and the power conversion device is commanded to produce the expected rectified power when the potential conversion efficiency is greater than or equal to the expected conversion efficiency. When the potential conversion efficiency is less than the expected conversion efficiency, the rules are updated.
