Definitions

  • Wetherill & Brisebois ABSTRACT Fluid-control system comprising fluld-control means having a positive viscosity-resistance characteristic the flow resistance of which increases with an increase in viscosity. and further comprising vortex means having a negative viscosity-resistance characteristic the flow resistance of which increases with a decrease in viscosity to compensate for changes in the flow resistance of the fluid-control means due to changes in fluid viscosity.
  • the vortex means is provided with a circular hollow chamber.
  • This invention relates to a fluid-control system. comprising a viscosity compensating device adapted to compensate for changes in the viscosity of a viscous fluid flowing through the control system, so that the operative characteristics of the system may be kept constant.
  • fluid-control systems comprising a plurality of pure fluid control elements are greatly influenced by changes in the viscosity of the viscous fluids used as operative fluids.
  • a pure fluid control element comprises a chamber enclosed by sidewalls, and a main nozzle from which the fluid, hereinafter referred to as a main jet,” is introduced, at high speed, into the chamber. Output ports in the chamber receive the main jet. Control nozzles deflect the main jet, so that the output ports are supplied with the main jet in different proportions. Pure fluid control elements of this kind may be classified as belonging to one or the other of two types, depending on the conditions controlling the deflection. One type is an element deflecting the main jet proportionally to the input to the control nozzle. and is called a jet deflection proportional amplifier. The other type is a wall-attachment amplifier wherein the deflected condition is maintained stable by the wall-attachment or Coanada effect.
  • the primary object of this invention is to provide a fluidcontrol system comprising a simple and effective viscosity compensating device
  • Another object of the invention is to provide a fluid-control system comprising fluid control means having a positive viscosity-resistance characteristic and vortex means having a negative viscosity-resistance characteristic which compensates for changes in the viscosity of the fluid in the fluid control means.
  • FIG. I IS a plan view of the plate 1 of a viscosity compensatmg device connected to a wall-attachment element according to the present invention as seen from the left of FIG. 2, with the plate 2 removed;
  • FIG. 2 is a side elevation of the device shown in FIG. I;
  • FIG. 3 is a cross-sectional view showing a vortex-type element used to describe its theoretical operation.
  • a pure fluid control element such as a wall-attachment element utilizing two dimensional flow is not actuated until the Reynolds number in its main nozzle becomes larger than a specified value.
  • Re becomes a function of v. that is, Re becomes larger with an increase in v, when the main nozzle of the identical size and the identical operative fluid are used. It is, however, uneconomical to increase Re more than required to increase the quantity of fluid used in fluid control system. Thus, it is desirable to set Re within a preferable range, but as previously mentioned, the viscosity of the fluid changes considerably with changes in temperature, and thus Re is influenced by 1/. Re changes with a change in 1/, even if v is constant. Thus, in order to keep R0 constant, it is preferable to change v in direct proportion to the change in :1.
  • flow rate Q changes with a change in pressure difference Ap.
  • the pressure downstream of the main nozzle is approximately constant. and thus the change in flow rate Q is substantially equal to the change in pressure upstream of the main nozzle. Therefore, in order to keep the Reynolds number Re constant, the pressure upstream of the main nozzle may be changed in direct proportion to the change in viscosity.
  • the flow resistance is as follows.
  • a vortex amplifier comprises a cylindrical vortex chamber, a tangential supply port, and a central output port.
  • fluid When fluid is introduced from the supply port into the vortex chamber, fluid issues from the output port following a vortex path in the vortex chamber.
  • the pressure drop in the vortex chamber is given as a function of the radial distance from the center of the vortex chamber.
  • This negative viscosity-resistance characteristic hereinafter referred to as a negative characteristic.
  • connection of the vortex-type element to the pure fluid control element causes the vortex element to automatically regulate the supply pressure or flow rate to the pure fluid element to keep the Reynolds number in the main nozzle of the pure fluid element constant, even if the viscosity of the fluid in the pure fluid element is changed.
  • a wall-attachment element 20 is illustrated as a representative pure fluid control element.
  • a vortex type element 10 is connected to the wall-attachment element 20 upstream thereof.
  • the vortex-type element compensates for changes in the viscosity of fluid in the wall-attachment element.
  • a flat plate I is recessed to form both the wall-attachment element and the vortex-type element. and is tightly sealed to a flat plate 2.
  • the vortex type element 10 comprises a circular chamber 12, a tangential nozzle 14 and a central output port 15.
  • the nozzle 14 is connected to a pressure fluid supply source (not shown) through a supply port 11.
  • the wall-attachment element 20 is provided with a main nozzle 23. a pair of control nozzles 24 and 25. a chamber 22 and a pair of ducts 28 and 29.
  • the main nozzle 23 extends at one end into the chamber 22 and communicates at the other end with a supply port 21 connected to the output port 15 of the vortex-type element 210.
  • the control nozzles 24 and 25 extend from opposite sides into the chamber 22 at substantially right angles to the main nozzle 23. and are respectively connected to control ports 33 and 34.
  • the chamber 22 is di- 5 vided into the two ducts 28 and 29 by a divider 30.
  • a pair of vent passages 31 and 32 open respectively into the ducts 28 and 29 downstream of the chamber 22.
  • the ducts 28 and 29 are respectively connected to output ports 26 and 27.
  • Operative fluid having a certain viscosity for example. an incompressible fluid such as oil, and supplied through the supply port 11. enters along the wall 13 into the chamber l2 through the nozzle 14, following a vortex path.
  • This vortex flow decreases the pressure in the center of the chamber 12 and this pressure decreases as the radial distance from the center decreases.
  • the viscosity of the fluid is decreased. the viscous resistance of the fluid is decreased, so that the vortex flow in the chamber 12 increases to increase the flow resistance. lnversely.
  • the viscous resistance of the fluid increases with an increase in the viscosity thereof. so that the vortex flow in the chamber is decreased to reduce the flow resistance.
  • a vortextype element to a pure fluid control element such as the wallattachment element permits the vortex-type element to compensate for changes in the viscosity of the fluid in the wall-attachment element.
  • the fluid from the output port 15 of the vortex type element 10 issues into the chamber 22 through the supply port 21 and the main nozzle 23.
  • This main jet adheres to one of walls 35 and 36 in the chamber 22.
  • This phenomenon is called the wallattachment effect or Coanda effect. by which deflected condition is maintained stable.
  • the main jet issues initially from the left output port 26. if a control flow is introduced into the control nozzle 24. the main jet is deflected to the right and then adheres to the wall 36 in the chamber 22.
  • the main jet continues to leave from the right output port 27 until a control flow is introduced into the control nozzle 25.
  • Under one stable condition. the greater part of the main jet is supplied to the next device to be operated through the left output port 26. while under the other stable condition. the greater part of the main jet is supplied to the next device through the right output port 27.
  • the next device is operated in response to the difference in momentum between the control flows supplied to the control nozzles 24 and 25.
  • Vent passages are required to maintain the deflected condition stable even when the loads exerted on the output ports 26 and 27 are increased.
  • the main jet when in a stable condition. is responsive to jet speed in the main nozzle.
  • the shape and size of the main nozzle. and the viscosity of the main jet an is usually designed to that the Reynolds number in the main nozzle is more than 5 4X10
  • the Reynolds number Re is given by equation l and changes with any change in the viscous resistance in the hydraulic circuit without compensation for such change.
  • the entrainment characteristic of the main jet is changed. which causes a change in the time required for switching between deflected conditions. Consequently. the flow rates and pressures in the output ports 26 and 27 are changed.
  • the vortex element 10 connected to the main nozzle 14 serves to compensate for such conditions. in response to changes in fluid viscosity. and thus automatically regulates the pressure and flow rate of fluid supplied to the main nozzle.
  • the vortex element serves to maintain the Reynolds number in the main nozzle constant. Consequently, the operative characteristic of the hydraulic circuit is kept stable. and is unaffected by changes in fluid viscosity, which results in increased accuracy and reliability in the control of the hydraulic circuit.
  • the vortex element While the vortex element is connected to a wall-attachment element in the above embodiment, the vortex element may be applied to a jet deflection proportional element or like element, and almost the same efi'ect may be obtained. Further while the vortex element is applied to one pure fluid control element in the above embodiment, the vortex element may be applied to a plurality of pure fluid control elements. In this case, the vortex chamber and tangential nozzle of the vortex element are designed to compensate for the viscosity changes of all the pure fluid elements.
