Claims
- 1. Formation of two isolated chambers between two solid preferably parallel opposite plane plates, which chambers are being separated by a solid partition, containing a through channel that is being slotted in full depth of both said chambers and defined as jet-stream passing channel.
Defining the first chamber, as a pneumatic control chamber and organizing therein the steady-state flow of a free planar compact jet-stream so that said jet-stream flow will divide the inside space of said chamber into two independent pneumatic cavities, without mixing with surrounding control gas, and will flow into the second adjacent chamber through the said jet-stream passing channel of said solid partition. The jet-stream passing channel is being arranged so as to be hydraulically long and axial with an opposite outlet portion of hydraulic power supply channel, which is being established to open inward the said pneumatic control chamber. Defining the second adjacent chamber, as a hydraulic intake chamber and processing therein the following techniques:
intake of compact free planar jet stream, flowing out from control pneumatic chamber and entering hydraulic intake chamber through the said jet-stream passing channel; sharing an impulse impact of said planar jet-stream flow into at least two submerged output hydraulic channels that are being arranged aside at least one splitting facilities in said hydraulic intake chamber; forming the thrust reactive flows from the excess of liquid that can't pass through said output hydraulic channels, and then routing said thrust reactive flows into the enlarged vent liquid free flow channels; deaeration of the vent liquid free flows inside said enlarged vent liquid free flow channels.
- 2. Method as claimed in claim 1, comprising formation of the steady-state flow of a quasilaminar free planar jet stream, running along its free path trajectory throughout the pneumatic control chamber without mixing with surrounding control gas and dividing the inside space of said chamber into two separate and preferably symmetric pneumatic cavities, where each of two free side surfaces of said planar jet-stream flow faces the juxtaposed pneumatic cavity and functions as an elastic movable wall of said cavity. The state of steadiness of said planar jet-stream flow is being enabled in the result of creating rated conditions for proper use the surface tension effect at the gas-liquid-solid interfaces and constant maintaining of soakage zones at the liquid-solid interfaces of any side surface of said jet-stream flow.
- 3. Method as claimed in claim 2, which comprises proper selecting of relationship among physical and chemical characteristics of solid, liquid and gas stuffs for processing the claimed method, and comprises choosing of rated correlation among Re, We, St numbers of said quasilaminar free compact planarjet-stream flow so that the results of said apt selecting and choosing should enable performing the following techniques:
keeping the steady-state shape of each side free surface of jet-stream flow by using the stabilizing effect of surface tension forces upon solid-liquid and liquid-gas interfaces, including said stabilizing soakage zones, and therefore maintaining a nearly parallelepipedic shape of core of said free planarjet-stream flow; avoiding the harmful undulation, turbulization and droplet breaking of both side free surfaces of the planar jet-stream flow, therefore keeping jet-stream flow core nearly invariable along all its straight or bended trajectory of free path throughout the said pneumatic control chamber and jet-stream passing channel, hence minimizing the loss of initial jet-stream flow impulse and so effectively pressurizing the entrance opening into hydraulic intake chamber; arising the sub-atmospheric pressure inside both pneumatic cavities by creating proper conditions for entrapment of surrounding control gas by the running side free surfaces of the jet-stream flow, thus and so converting each said pneumatic control cavity into high-sensitive pneumonic two-port with elastic movable wall, where this wall is actually none other than the straightly running or flexibly bending said free planar compact jet-stream flow.
- 4. Method as claimed in claims 3, comprising formation of locking fluid whirls in gaps between each side entire liquid free surface of the planar jet-stream flow and adjacent side solid surface of the jet-stream passing channel so that said locking fluid whirls are being maintained at steady dynamic equilibrium in limits of hydraulically long jet-stream passing channel. The said locking fluid whirls are being created by a liquid-gas mixture, which climbs upstream from the highly pressurized hydraulic intake chamber and trends in vain to enter the low positively or even negatively pressurized pneumatic control chamber but is being entrained back downstream by the jet-stream flow entrapment. This phenomenon is being kept at any static or dynamic status of planar jet-stream flow (i.e. axial, or bent, or vibrating status). The said formation of locking fluid whirls is being accomplished by the rated correlation of geometrical and hydraulic characteristics of the jet-stream flow with geometrical shape and dimensions of the jet-stream passing channel.
- 5. Method as claimed in claims 2 and 3, comprising an angle bending of compact planar jet-stream flow inside the pneumatic control chamber under pressure difference between the opposite inverse control pneumatic cavities of said chamber, which pressure difference is being organized by applying either distributed or lumped pressure, or both said kinds of pressure simultaneously, where said angle bending is being accomplished in analog or impulse modes by applying the following optional techniques:
increasing of vacuum rate in one cavity versus the other inverse cavity of the pneumatic control chamber, where said increasing is being fulfilled by throttling or blocking in full the draw input of gas inward the said pneumatic cavity from outside surrounding gas ambient; decreasing of vacuum rate in one cavity versus the opposite inverse cavity of the pneumatic control chamber, where said decreasing is being carried out by the forced gas inflowing into the said pneumatic cavity; impacting upon the side surfaces of the jet-stream flow with a control gas jets, where said control gas jets are being applied upon said surfaces inversely; applying distributed and lumped pressure differential either alternatively or simultaneously but ever at the same impulse or monotonous mode; simultaneous increasing/decreasing of vacuum rate in the opposite inverse said cavities by said techniques, which are being applied in antiphase mode.
- 6. Method as claimed in claim 1, comprising the art of forming thrust reactive flows from excess of liquid that can't pass through output channels of the hydraulic intake chamber, where said thrust reactive flows are being rated, designed and spatially positioned at an angle regarding the initial, not deflected trajectory of planar liquid jet-stream flow so that:
the thrust reactive impulse of each of said flows is being applied to the input zone of the adjacent hydraulic output channel; the thrust reactive forces, acting on and hence enhancing pressure in said adjacent hydraulic outputs are being created by the rated throttling of excess liquid vent flows within said thrust reactive channels; the high-speed thrust reactive flows are being converted downstream into the enlarged low-speed free running vent liquid flows, draining in turbulent flow regime outside of the hydraulic intake chamber.
- 7. Method as claimed in claim 1, comprising the art of deaeration of combined gas from the vent liquid free flows so that:
the first stage of releasing the combined gas from draining liquid is being organized by converting the pressurized quasilaminar thrust reactive flows into the turbulent slow-speed free running vent liquid flows; the second stage of releasing the combined gas from turbulent slow-speed free running vent liquid flows is being accomplished by pouring down said flows upon free liquid surface of hydraulic reservoir in the mode of developed turbulence.
