Definitions

  • the present invention relates to a pair of chambers, which work with fluid, with a mechanism inside which has the characteristic of increasing the pressure. They can be mounted in series so that it is possible to multiply the pressure to very high levels, without having as a limitation the tension of the material with which it is constructed, so that any sample or pieces that you want to observe or modify can be subjected to very high pressure in some of its properties.
  • diamond anvil cell There is the "diamond anvil cell” technique where the highest pressure is used experimentally, because the conditions generated from very high pressures reach a very small volume, because it is achieved by storing the sample between two diamonds, one above and another from below, surrounded by a sheet. It is used experimentally, in studying superconductors, semiconductors and varied characteristics that present various materials in extreme pressure conditions; It is used in simulating pressure conditions that would have different materials inside the earth, in the elaboration of diamond dust, etc.
  • Pressure multiplier mechanism which mounted in series; one inside the other, allows to obtain any pressure without being limited by the material that the chambers are constructed nor of the size of the sample to reach the desired pressure.
  • the system Given a pressure P1, which can be achieved with a pump, the system generates conditions so that in the environment that is the pressure P1, with a new "motor” and “pump”, pressures P2, higher than P1, and stay in a new chamber 2, which is inside the chamber 1. Then, with a new mechanism, increase the pressure to P3, then to P4 and so on.
  • the pressure can be used for the manufacture of pieces of sintered material at very high pressures; manufacture of parts with new materials such as synthetic diamond; manufacture of material for drugs, pressure washer using the new technique to raise pressure, etc.
  • the pressure multiplier mechanism works viewed from the outside, as a device, which is entering a fluid flow rate at a given pressure and delivers a portion of the lower pressure fluid flow rate and with the energy released by this portion, it serves so that the other portion of the fluid flow obtain a higher pressure.
  • the pressure multiplier mechanism has two chambers, one inside the other and a system consisting of two cylinders with their respective pistons or pistons that work simultaneously. First a description of the cylinders and pistons will be made. Then you will see how a pressure multiplier mechanism is mounted with another and this in turn with another and so on, finally some variants of the mechanism are seen.
  • a cylinder with its respective piston They are two pieces: one is the piston or piston and the other is the cylinder that is closed at one end.
  • at least one piston cylinder must be constructed of two pieces that are solidly mounted.
  • One part does not move with respect to the other, forming a piston cylinder as a solid piece.
  • the two cylinders constitute a part and the two pistons another, so that when a piston works inside a cylinder, the other piston simultaneously works with the other cylinder.
  • the cylinder-pistons go inside the outer chamber, but outside the inner chamber. Both cylinders have two flexible pipes: one that brings the liquid to the cylinder and another where the liquid comes out of the cylinder.
  • a cylinder acts as a pump because it brings liquid under pressure Pa and raises the pressure to Pb, greater than Pa and leaves it in the inner chamber.
  • the other cylinder acts as an engine because it lowers the pressure of Pa to Pm and leaves it outside the outer chamber, which allows the pressure in the pump to rise.
  • the VIM valve can be attached to the wall of the chamber or to one of the cylinders, in the latter case it must be connected to the bar of the pressure differential sensor CDP, so that it transmits the deformation of the chamber. Or another mechanism that transmits the pressure difference. Simultaneously the pump cylinder starts working. It starts to filling liquid from the chamber itself through a simple VR check valve. When the expansion stroke ends, the VIM valve is closed and the engine evacuation valve, VEM, is opened by a mechanism that activates it when it reaches the top of the cylinder.
  • the liquid that has the engine cylinder is released out of the external chamber and simultaneously begins to discharge the pump cylinder through another VR check valve, to the chamber that is inside, chamber 2, at a pressure greater than Pa
  • the VEM valve is closed by the mechanism indicated by another stop.
  • the chamber 1 will have lowered the pressure slightly, because the pump pumped into the inner chamber or chamber 2 and the motor evacuated outwardly from the outer chamber or chamber 1, therefore the pressure Pa will have to be recovered first in the chamber 1, to continue with another pumping to chamber 2. There will be so many pumping to chamber 2 until it reaches pressure Pb.
  • the cameras are compressible; that is, change its volume with the liquid under pressure.
  • the liquid is also compressible, because its specific volume changes with the pressure. This is a desirable and necessary characteristic of the chamber and the liquid, because the pressure multiplier mechanism cannot work inside the chambers, if they are not compressible.
  • An alternative is to simulate that the liquid is compressible by introducing to the liquid within chamber 1 a rubber sphere that will be inflated with a gas, which if compressible in the range of pressures you are working on.
  • a characteristic of the engine is that unlike all the usual engines, it does work on the pump, when the engine cylinder contracts. This is because strictly speaking, the engine cylinder delivers its energy to the chamber fluid when it is filling and after the chamber fluid passes to the pump cylinder, when it is evacuated at higher pressure to the next chamber and the engine cylinder evacuates to the exterior of the cylinder 1.
  • Another aspect that attracts attention is that the mechanism does not have a crankshaft or connecting rods or axle. It is not a moment of torsion because of what It needs to be attached to a base, as usual in engines and pumps. It is suspended in the liquid inside the chambers by flexible pipes.
  • the chamber 2 has a simple VR check valve, so that liquid enters but cannot exit and has a VDS 1 discharge or safety valve so that if the pressure inside the chamber exceeds a relative pressure value , preset, lets liquid escape into the anterior chamber. If, instead of having an empty chamber 2, we put a pressure multiplier mechanism using chamber 2 as chamber 1 of the new smaller pressure multiplier mechanism, a system with three chambers would remain and if we put another pressure multiplier mechanism internally and so on until there are N mechanisms mounted in series, so that it is possible to multiply the pressure to values that exceed the resistance of any material.
  • VARIANTS instead of being pistons and pistons they can be bellows or a hydraulic motor for example of gears, connected with a hydraulic pump for example of vanes, which operate at relatively low pressure.
  • the operation of the mechanism can be with liquid or gas or both. This may be working with a gas, steam at 100 0 C for example, and to make the operation a portion will increase the pressure and part of the steam condenses inside the cylinder when the pressure rises. To separate the gas from the liquid, it has a trick valve through which the liquid comes out.
  • VIM Engine Inlet Valve acts upon entering the liquid that feeds the mechanism from outside the chambers and discharges it into the chamber outside the cylinder, if the pressure is lower than a preset value or inside the engine cylinder if the pressure is equal to or greater than the preset value.
  • This valve acts by a captor of the pressure difference CDP between the chamber and outside and is adjusted so that the liquid is derived to the engine if it reaches the preset value.
  • CDP pressure differential sensor This sensor works with the deformation that the walls of the chamber undergoes when receiving pressure. The higher the pressure, the greater the deformation.
  • This captor basically consists of a long bar that is inside the chamber, with one end fixed to the chamber and the other free. By pressure difference between the chamber and the outside, the chamber is deformed by moving the free end; activating the VIM valve, which is fixed to the edge of the engine chamber.
  • VEM engine exhaust valve This valve allows the discharge of the engine cylinder. When the plunger reaches its maximum; a stop, the valve is activated allowing the discharge to the outside of the chamber. When it reaches a minimum; another stop, the valve is closed and allows filling again.
  • Discharge or safety valve VDS This valve is activated only if the pressure difference sensor between the chambers and the anterior chamber acts, enough to deform the chamber.
  • a thin bar is housed inside the chamber so that it has a fixed end to the chamber and the other operates a check valve, fixed to the chamber, only if the deformation of the chamber is high enough.
  • Simple VR check valve It is a valve that passes liquid only in one direction. In the entrance of liquid to the pump, in the discharge of the pump and at the entrance of the chamber there is a simple VR check valve. It is so that it never allows more pressure in a chamber that is more outside
  • Cylinder-pistons Two pistons and two cylinders, rigidly connected, so that when a piston is moved in its cylinder, the other piston must be moved in its cylinder. There is a mechanism between the two cameras.
  • VRS simple check valve and discharge or safety valve VDS They are mounted in the inner chamber. The RSV is so that the liquid between the liquid and the VDS is so that the pressure is not exceeded.
  • Bar outside the cylinder It is a bar that is mounted fixed to a cylinder and activates or deactivates the exhaust valves of the VEM engine, which is fixed in the other cylinder.

Abstract

L'invention concerne un mécanisme multiplicateur de pression, formé de deux chambres montées l'une à l'intérieur de l'autre, et comprenant deux cylindres et deux pistons interconnectés de manière spécifique au milieu des deux chambres; qui permettent d'augmenter la pression du et de la maintenir dans la chambre intérieure. La chambre extérieure prend une quantité de fluide Qa à une pression Pa et rend une quantité Qm inférieure ou égale à Qa à une pression Pm inférieure à Pa et génère un débit égal à Qa - Qm à une pression supérieure à Pa. Divers mécanismes peuvent être montés en série. Il existe deux types de montage en série. Le premier est le type de montage habituel dans lequel chaque mécanisme reste à l'extérieur de l'autre. L'autre montage en série présente uniquement un mécanisme connecté dans sa partie intérieure à un autre mécanisme et ainsi de suite, permettant ainsi d'atteindre n'importe quelle pression, sans que celle-ci ne soit limitée par le matériau utilisé dans la construction des chambres, ni par la taille de l'échantillon.
