Definitions

  • the invention has the advantage that whilst existing rotary valves consisting of a stator and a rotor have the rotor driven by means of an electric motor gearbox and coupling device connecting the gearbox output shaft to the rotor, the invention replaces the gearbox and coupling device with a gear or belt driven system.
  • the overall system is simpler with a reduced number of parts.
  • the rotor member gear tooth profiles are an integral part of the rotor body.
  • gear reduction is provided by a small gear or pinion on the driving motor shaft and a large gear profile around the circumference of the rotor, thereby achieving a step down gear and increase in effective torque without having a separate gearbox.
  • an additional coupling device to connect the motor to the rotor as with prior art systems is not required.
  • Figure 1 is a schematic view of a rotary valve according to the invention
  • FIG 3 is an exploded view of the first and second rotors according to a preferred embodiment of the invention.
  • the rotary valve is mounted as shown in Figure 1 on a plate above which is located a motor 13 with a drive pulley 14 fixed directly onto its drive spindle 15.
  • a toothed belt 16 is driven by the drive pulley 14 and engages with the toothed profile of the perimeter 20 of the first rotor 11, to rotate the rotors 11 and 12 relative to the stator 10.
  • the rotors 11, 12 can be driven in any direction by the motor.
  • the rotor 11 tooth profile around the perimeter is an integral part of the rotor 11.
  • a suitably tensioned belt drive 16 connects the two pulley profiles and gear reduction is achieved by the relative number of teeth on each pulley profile.
