With reference to the example shown in FIG. 2( c ), the feedback orifice 36 is provided in a sidewall of the sleeve 14 (in a manner similar to that in FIG.
  • the solenoid spool valve 10 shown in FIG. 2( d ) has a feedback orifice 36 formed as a duct 38 extending through the first piston 26 to communicate with the control pressure port 18 .

This independence is due to equal and opposite face surface areas of the first piston 26 , which effectively cancel each other. Where the first piston 26 is cylindrical, the combined force on the spool 22 from fluid against piston faces of the spool 22 is independent of an outside diameter of the first piston 26 . With regard to the lettering shown in FIG. 3 , the combined force on the spool 22 from fluid against piston faces of the spool 22 is given by the equation:
  • the first piston 26 has a larger diameter than the second piston 30 so that the first piston 26 has a larger piston face surface area in fluid communication with the control pressure port 18 than does the second piston 30 .
  • the valve 10 has relatively high flow from the supply pressure port 16 to the control pressure port 18 and relatively low flow from the control pressure port 18 to the exhaust port 20 . This is desirable, as the relatively low flow from the control pressure port 18 to the exhaust port 20 minimises leakage such that a smaller pump may be used.
  • the ability to increase the diameter of the first piston 26 enables higher control pressure to be used, assisting in the regulation of higher pressures and facilitating quick action of the solenoid spool valve 10 .
  • the pressure can be adjusted by varying the diameter of the first piston 26 while maintaining a common coil/core size between pressure/flow variants. This may assist in maintaining an overall short length when compared with other high flow solenoids, and facilitates the provision of a family of solenoid designs using a common magnet coil/core and body.
  • the tunable feedback orifice 36 may have a maximised effect by being located to cooperate with the largest area of the spool 22 .
  • the solenoid spool valve 10 may have a filled canister whereby oil is provided inside the electromagnetic actuator to change the natural frequency of the solenoid spool valve 10 . Also, a trimming screw 44 may be mounted as shown in FIGS. 2( a ) to 2 ( d ).
  • FIG. 4 there is shown a diagrammatic view of an example system incorporating a solenoid spool valve 10 in accordance with the invention.
  • the solenoid spool valve 10 is used in combination with a seat base/cushion 56 to control operation of the seat base/cushion.
  • the solenoid spool valve 10 receives information from a sensor 46 via an on board controller (OBC) 48 .
  • OBC on board controller
  • the OBC is connected by wiring to a master controller 58 .
  • FIG. 5 shows an example system incorporating a plurality of solenoid spool valves 10 , each of which is provided with a separate OBC 48 , and an individual identifier such that the individual solenoid spool valves 10 are able to be operated individually.
  • the solenoid spool valves 10 are connected by communication wires 50 .
  • the communication wires 50 can be a combination of the power and CAN wires such that the CAN signal is “injected” on top of the power wires thus requiring only two wires to be connected to each solenoid assembly. As the communication wires 50 connect to the master controller 58 in an endless loop, this allows for continued power and CAN communication from either direction in the even that a wire or connection is faulty, thus making the system more robust and failsafe.
  • FIG. 6 shows an OBC 48 of a solenoid spool valve 10 with a series of possible CAN nodes that could be used by the OBC 48 to measure responses. More specifically, the diagram shows a range of different sensors 46 that could be used by the OBC 48 to measure responses, depending on the nature of the request quantity type which is received by the OBC 48 .
  • the sensor 46 is arranged to sense a control value of the spool valve, and the OBC 48 receives a request and is arranged to control delivery of power to the electromagnetic actuator of the solenoid spool valve 10 with feedback from the sensor 46 until the control value meets the request.

  • the CS would automatically adjust itself to wear over its lifetime and adjust itself to suit its environment.
  • the CS can be “labelled” to have a distinguishing number or identifier so that many solenoids of the same type can be used on the same CAN line where only the identifier is different so that each solenoid has its own unique ID address so that when CAN requests a pressure change, it could ask each solenoid individually to perform the change as requested and when requested.
  • Variations of the invention include but are not limited to:
