Abstract

The invention relates to a machine for continuously compressing liquid or gaseous fluids, without lubrication, using a semi-spherical circular wheel which supports vanes and is guided in a semi-spherical circular chamber that is eccentric to the wheel. The compression is performed by means of semi-spheroidal vane technology. The vanes are made from deformable synthetic material. The sealing is provided by a continuous line that runs from the side wall on one side to the side wall on the opposite side, without any form-altering angles. The machine operates without oil owing to its self-lubricating synthetic vanes. Moreover, the machine can also pump, under high pressure, liquid fluids that are not be mixed with the lubricating oil of ordinary pumps.

DESCRIPTIF  DESCRIPTION
COMPRESSEUR OU POMPE ROTATIVE A PALETTES SEMI- SPHERIQUES « SANS HUILE « POUR COMPRIMER OU POMPER COMPRESSOR OR ROTARY PUMP WITH SEMI-SPHERICAL "OIL-FREE" PALLETS FOR COMPRESSING OR PUMPING
LES FLUIDES GAZEUX OU LIQUIDES  GASEOUS OR LIQUID FLUIDS
La présente invention concerne une machine qui permet de comprimer sans lubrification , les fluides liquides ou gazeux en continu au moyen d'une roue circulaire semi-sphérique qui supporte des palettes , elle est guidée dans une chambre circulaire semi-sphérique ayant une excentricité par rapport à la roue. The present invention relates to a machine which can compress liquid or gaseous fluids continuously by means of a semi-spherical circular wheel which supports pallets, it is guided in a semi-spherical circular chamber having an eccentricity with respect to at the wheel.
La technologie est du type compresseur ou pompe à palettes. The technology is of the compressor or vane pump type.
L'innovation consiste a utiliser une forme de chambre particulière de compresseurs à palettes type « semi-sphérique » avec l'utilisation de palettes déformables synthétiques , elle a comme avantage d'effectuer Pétanchéité sur une ligne continue commençant de la partie latérale d'un coté jusque l'autre partie latérale de l'autre coté. Cette invention peut être appliquée pour les gaz compressiblesThe innovation consists in using a particular type of "semi-spherical" vane compressor with the use of synthetic deformable pallets, it has the advantage of sealing on a continuous line starting from the lateral part of a side to the other side on the other side. This invention can be applied for compressible gases
Demandant une grande étanchéité type compresseur d'air mais Requiring a great air compressor type sealing but
Aussi pour des pompes de liquides hautes pression nécessitant aucune pollution par l'huile de lubrification . La machine figure 1 est composée de : Also for high pressure liquid pumps requiring no pollution by lubricating oil. The machine figure 1 is composed of:
Deux demi carter extérieur (1) contituant la chambre semi-sphérique de compression. Une roue circulaire et semi-sphérique excentré par rapport au carter ayant comme fonction de supporter les palettes (3) guidées dans des gorges (5) qui laissent coulisser ces dernières vers les parois de la chambre du carter ; lors de la rotation de la roue l'effet centrifuge pousse ces palettes contre les parois fixes de la chambre. Two outer half shell (1) contituting the semi-spherical compression chamber. A circular and semi-spherical wheel eccentric with respect to the housing having the function of supporting the pallets (3) guided in grooves (5) which slide the latter towards the walls of the chamber of the housing; during rotation of the wheel the centrifugal effect pushes these pallets against the fixed walls of the chamber.
Des palettes en matière synthétiques à faible coefficient de glissement type PTFE et déformable grâce a une rainure permettent de s'adapter sur les parois du carter et ainsi d'effectuer une étanchéité. Pallets of synthetic material with a low sliding coefficient PTFE and deformable thanks to a groove make it possible to fit on the walls of the housing and thus to seal.
Deux rondelles (4) en matière synthétiques à faible coefficient de Frottement type PTFE situées sur les parois latérales assurent l'étanchéité Entre les palettes et les parois latérales de la chambre. Two washers (4) of synthetic material with a low coefficient of PTFE-type friction located on the side walls ensure tightness Between the pallets and the side walls of the chamber.
En figure 2 est représenté : In Figure 2 is shown:
Un orifice (6) permet de laisser entrer le fluide dans le compresseur, il est aspiré par la variation de volume engendrée entre chaque palette lors de la rotation. An orifice (6) allows the fluid to enter the compressor, it is sucked by the volume variation generated between each pallet during rotation.
Un orifice (5) permet de laisser sortir le fluide du compresseur , il Est poussé vers cette sortie par la variation de volume engendré entre Entre les palettes lors de la rotation ( la position de l'orifice est différente Suivant le type de fluide liquide ou gazeux ) . An orifice (5) makes it possible to let the fluid out of the compressor, it is pushed towards this outlet by the volume variation generated between the paddles during the rotation (the position of the orifice is different depending on the type of liquid fluid or gaseous).
