Definitions

  • ABSTRACT An impact deflection fluid amplifier comprising [54] FLUID IMPACT DEFLECTOR AMPLIFIER a plate provided with a main supply channel and a secondary 2 Claims, 4 Drawing Figs. supply channel placed coaxially so as to transmit two opposing 52 U.S.
  • the present invention concerns a fluid impact deflection amplifier for obtaining differential output pressure, proportional to an input differential pressure.
  • the invention especially has the object of avoiding such d'madvantages.
  • the amplifier makes a kind of bidimensional impact modulator of a very different type from conventional impact modulators which have neither differential inputs nor outputs.
  • the invention more precisely has for its object an impact deflection fluid amplifier characterized in that it comprises a plate in the body of which is provided a main supply channel and a secondary supply channel placed coaxially so as to.
  • FIG. 1 is a diagrammatic view in section of the impact deviation amplifier.
  • FIG. 2 is a diagrammatic representation of the form of the impact of two jets in the absence of cross-control pressure.
  • FIG. 3 is a diagrammatic representation of the shape assumed by said impact when a transverse control pressure is applied.
  • FIG. 4 is an illustrative diagram.
  • FIG. 1 one sees the amplifier formed by an assembly of channels, engraved, for instance in a plate P, and closed by means of a flat lid (not shown).
  • the reference numeral 1 designates the main supply channel, and the reference 2 the secondary supply channel. Said channels are arranged coaxially facing each other, so as to emit jets in opposition, the jet coming from the channel I having a higher pressure than that coming from the channel 2.
  • the amplifier operates as explained hereafier.
  • control pressure a pressure called control pressure
  • the pressure of the fluid passing by channel 3 depends on the pressure in channel 4. One this obtains at the output of the channels Q, 3, a considerable variation of differential pressure resulting from a low variation of the control pressure,
  • the amplifier being symmetrical in relation to the axis XX, it goes without saying that one can use either one or the othei of the channels 4 and 4' for applying the control pressure, and that one can also use these two channels at the same time.
  • the diflerence of the output pressures P, and P5, passing through the channels 3 and 3' is proportional to the control pressure of the channel 4, or to the control pressure of the channel 4', or to the difierence of the control pressures P. and F1, in the channels 4 and 4'.
  • FIG. 4 shows how, in this example, the difference of the output pressures Py-P 'varies with respect to the difference of the control pressures PrP t
  • FIG. 4 shows particularly that if the pressures of the control channels are equal, no amplifying effect occurs and the output pressures are the same. On the contrary, if there is a slight difference between the pressures of the control channels 4 and 4', one obtains a high difierence between the pressures in the output channels 3 and 3' and therefore a great amplifying effect.
  • Another advantage of the amplifier according to the invention is the ability to regenerate at the output, a very much larger percentage of the supply pressure from the main channel.
  • An impact deflection fluid amplifier for obtaining amplified differential output pressure comprising a platelike body having a main supply channel and an opposed coaxial secondary supply channel for supplying opposed jets of fluid, supplemental channels open to the air intersecting said supply channels at the intersection thereof, the jet from the main supply channel being at a higher pressure than the pressure of the jet from the secondary supply channel, two opposed control channels normal to the axis of the main supply channel and adjacent the exit thereof for supplying control fluid pressures to deviate the jet from the main supply channel and two opposed regenerating channels extending at an acute angle to the axis of the secondary supply channel and adjacent the exit thereof for receiving the fluid introduced by said supply channels under pressures which are dependent on the pressures issuing from said control channels.
  • An impact deflection fluid amplifier as claimed in claim 1 wherein said supply channels, control channels, supplemental channels and regenerating channels have axes lying in a common plane, said two regenerating channels extending at substantially the same acute angle to the axis of said secondary supply channel.
