Definitions

  • the fluid volume or flow rate controlled by the ratio to/tc but also by varying the effective open area of the orifice being modulated.
  • the modulated orifice opening can be controlled as to the size of the opening by applying a con ⁇ trol voltage to the bender. Either the inlet orifice or the outlet orifice or a combination of the two can be modulated as noted above.
  • the control is . accomplished by the operator of the equipment, such as a gas range, by a control means such as a rotating knob, a push button switch or by programming a control computer.
