  • Valve assembly with integral sensors
    Patent number: 9512933
    Abstract: A valve assembly includes an electronics housing and a valve housing assembly engaged to the electronics housing. The valve housing assembly includes a valve body defining a plurality of fluid ports in fluid communication with the valve bore. A plurality of fluid dampeners is disposed in the fluid ports. A sensor plate is engaged to the valve body. The sensor plate defines a plurality of sensor ports that are generally aligned with the fluid ports of the valve body. At least four fluid sensors are disposed in the plurality of fluid ports of the valve body. A cover is engaged to the sensor plate. The cover defines a cavity. A circuit board is disposed in the cavity of the cover. The circuit board is in electrical communication with the fluid sensors.

  • Spool valve
    Patent number: 8464756
    Abstract: A spool valve includes a housing defining a bore that extends along a longitudinal axis. A spool is disposed within the bore and is moveable between a first position for directing a hydraulic fluid along a first flow path and a second position for directing the hydraulic fluid along a second flow path. The spool includes a supply portion disposed between a first land portion and a second land portion. The supply portion includes an outer surface that defines a truncated pseudosphere for smoothly directing the flow of the hydraulic fluid across the surface of the spool.
