Definitions

  • ABSTRACT A fluid amplifier having a fluid flow inlet, a pair of fluid flow outlets, a control fluid flow inlet and a pivotable triangular flap member located in the branching point of the fluid flow outlets, said member being located downstream of the control fluid inlet and adapted to open either of said fluid flow outlets.
  • the flap member is free from direct actuation by the control fluid but is actuated by the fluid flow guided into either outlet and is pivotably journalled about an axis located within the triangular contour, whereby the flap member is automatically switched over to a position with the selected active outlet opened and the other passive outlet completely closed.
  • said member being pivotable and having a triangular contour in plan view and adaptedto openeitherof said fluid flow outlets.
  • the .fluid amplifiers originally developed 'i.e., those den unintended adjustments of the flap member. Furthermore, the adjustment ofthe flap "member can be controlled with small control-fluid pulses so that the fluid amplifier has a high rate'of'amplification. The direction of the flow also can be changed very quickly,
  • thefluid amplifier can bear very high loads and progressively or suddenly over to the passive outlet.
  • valve means such as flaps in such fluid amplifiers.
  • An example of this is the disclosure of the U.S. Pat. specification No. 3,053,276.
  • the structure according to said patent specification involves a certain improvement of the fluid amplifier and removes to a certain extent the drawback of instability as mentioned, but it has also turned out to have serious disadvantages.
  • the structure stated in said U.S. Pat. specification No. is such that the control fluid flow directly acts upon the valve flap arranged at the outlets of the fluid amplifier, and therefor a significant control fluid pressure must .be sacrificed to provide a switch-over. Also, the structure according to said Pat.
  • the feature; substantially distinguishing the present invention is .thatthe flap-member; is free from direct actuation bythe. controlfluid but is1instead actuated bytheintroduetion of-the fluid-flow into either of I theoutletsso that the-flap member then automatically will be switched over to aposition; with the selectedactiveoutlet opened and the, other passive outletzcompletely closed, said; flap member" being; pivotably joumalled about. aaaxislocated. within the; triangular contour.
  • the invention also. has aplurality of other important advantages. Firstly, it of courseprovidescomplete reliability with. complete elimination ofprogressi-veorsud:-
  • the fluid amplifier according to the present invention also is very well suited for connection with a fluid amplifier system, contrary to a mechanical valve.
  • the device of course can be used forgaseous fluids as well as liquids.
  • FIG. 1a and lb is a plan view in section and a longitudinal side elevational section of a principally basic embodiment of the invention
  • FIGS. 2, Lia-3c and FIGS. 4a-4c are various possible applications of said basic inventive principle
  • FIGS. 5-9 illustrate a further embodiment of the present invention, wherein FIG. 5 is a sectional plan view, FIG. 6 a longitudinal side elevational section, FIG. 7 an end sectional view, FIG. 8 an exploded perspective view and FIG. 9 a flow diagram of said further embodiment.
  • FIGS. la and lb thus is illustrated a common bidirectional fluid amplifier having afluid flow inlet 1' and two fluid flow outlets, one denominated a for active and the other p for passive.
  • the fluid flow entering from the inlet thus passes out through theoutlet a in the condition illustrated in FIG. la.
  • a flap member I which has triangular shape in plan view and in the present particular embodiment has the shape of a sector of a circle, such as is illustrated in FIG. la.
  • Saidflap member I is pivotally joumalled about a'pivot 2, which is located adjacent the peak of the circle sector or the center of the circular are surface.
  • Said circular are surface of the flap member is located downstream of the pivot 2 and is spaced with smallest possible clearance from the end surface 3 of the partition wall between the two fluid flow outlets at their branching.
  • Said end surface suitably has a contour shapefollowing as close as possible the circular arcuate surface of the flap member.
  • Said flap member 1 is freely pivotably joumalled on the pivot 2.
  • the operation of the flap member 1 is as follows: in the condition illustrated in FIG. la, the flap member gives-a free passage to the fluid flow jet going from the.
  • FIG. 2 there is illustrated an embodiment of the invention which is particularly well suited for application in hydraulic devices, thus having liquids as the flowing medium as well as the controlling fluid.
  • the flap member 1 has triangular shape, with however a contour at the base which is of opposite cylindrical configuration from the shape according to the first-mentioned embodiment; thus, the triangular flap member base is concave.
  • the pivot 2 is not mounted adjacent the flap member peak but closer to or substantially at the center of gravity of the flap member.
  • Said embodiment of the flap member peripheral contour and particularly the base line contour now makes it provide to provide a feedback conduit r at the end surface of the partition wall between the fluid flow outlets eetwe fl eebshale their branching.
  • Said feed-back or return conduit r has proved'to provide a particularly advantageous effect whenapplying the invention to fluids. Since liquids are substantially incompressible, fluid leaving the active fluid flow outlet can be returned in a very advantageous manner in an opposite direction through the passive fluid flow outlet so as to then be guided by the concave surface of the flap member 1 into the return flow conduit r.
  • attention must be paid to the pressure distribution over the concave base surface of the. flap member.
  • FIGS. 3a-3c A further improvement of the idea being the basis for the embodiment according to FIG. 3 leads to the embodiment of the FIGS. 3a-3c.
  • Said latter embodiment provides several different functions.
  • the feature substantially distinguishing said embodiment is that there are two flap members la and lb, respectively, arranged side-by-side in the same manner as the single flap mem ber l in the preceding embodiment.
  • the flow jet can be brought to flow from the inlet straight through the fluid amplifier between the two flap members la, lb, and out through the return conduit, which in this particular case can be considered as an outlet and therefore is denominatedu.
  • the two fluid outlets are then connected to either side of a piston in a cylinder as illustrated in the drawings, the piston in this position of the fluid amplifier and its flap member then being free.
  • a proportional control will be achieved, such that the piston 5 will move slowly, dependent upon the fact that a portion of the fluid flow is guided out through one fluid flow outlet while the remainder of the flow will be carried between the flap members directly to the outlet u. Fluid expelled from t'he 'opposite side'of the piston will return through the passive fluid flow outlet and pass the actual flap member, in this case flap member la, and be guided to the outlet 14.
  • both flap members are made as an intermediate step between the flap member shapes in the two preceding embodiments, i.e.,the flap means are mutually equal and shaped as a sector of a circle and pivotably journalled adjacent their peak, being however provided with a base surface which is concavely, circularly arcuate or cylinder-shaped.
  • FIGS. 4a-c illustrate each a practical embodiment of the basic inventive concept wherein the speed in the switching over and a low energy loss is of essential importance.
  • FIG. 4a illustrates the fluid amplifier according to the invention utilized for providing a guiding reaction force at each of the fluid flow outlets. If an oscillation is desired in the present case, this can be provided by the inertia of the flap member I or by having a feed-back of fluid through a capacity.
  • FIG. 4b illustrates how a piston force can be made useful, the comers or edges 4 in the down stream direction of the flap member 1 being made resilient, e.g. in the form of rubber ribs.
  • FIG. 4c illustrates how the fluid amplifier can be utilized for directly providing a rotational movement or a rotational momentum.
  • FIGS. 5-9 of the drawings a further improved embodiment can be utilized such as illustrated in FIGS. 5-9 of the drawings.
  • a flap member I in the branching between the fluid flow outlets is mounted a flap member I, but at its base side opposite to the pivot 2, which base side suitably is circularly arcuate, there is provided a connecting conduit 6, extending substantially parallel to said base side. At each end, said conduit 6 opens in a port or aperture at right angles to the plane of the flap member 1. Similarly, the two outlets a and p are connected to outlet conduits opening at right angles to the plane of the flap member. Between said outlet conduits a return condiut u to the power fluid source is also provided.
