Definitions

  • the present invention relates to a rotary machine rotary piston.
  • USA 2 965 039 describes a rotary volumetric machine for liquid fluid comprising the features of the preamble of claim 1.
  • the compression chamber is rotated by the piston; there is therefore contact between the compression chamber and the piston; which implies friction and if necessary the obligation to lubricate the machine.
  • the present invention provides a rotary machine according to the features of claim 1.
  • It consists of a cylindrical piston with an axis of eccentric rotation (3) moving radially inside a compression chamber (2) whose internal volume is composed of two half-cylinders at each end of a volume rectangular parallelepiped; itself in half rotation the speed of rotation of the piston.
  • the movement takes place without mechanical contact between the piston and compression chamber.
  • Synchronization of the piston and the compression chamber is ensured by a gear train (4) located outside of the compression chamber.
  • the piston, compression chamber, train assembly of gears is contained in a housing (1) provided at one end of two lights (5).
  • the lights are alternately open or closed in function of the relative position of the piston relative to the compression chamber.
  • the machine can consist of one or more stages on the same principle.

Description

La présente invention concerne une machine tournante à piston rotatif.
La machine peut être utilisée comme :
  • Compresseur volumétrique de fluide liquide ou gazeux
  • Moteur hydraulique ou pneumatique
  • Pompe volumétrique de fluide liquide ou gazeux
La USA 2 965 039 décrit une machine tournante volumétrique pour fluide liquide comportant les caracténstiques du préambule de la revendication 1.
Selon ce document la chambre de compression est entraínée en rotation par le piston ; il y a donc contact entre la chambre de compression et le piston ; ce qui implique des frottements et le cas échéant l'obligation de lubrifier la machine.
Pour remédier à ce problème. la présente invention propose une machine tournante selon les caracténstiques de la revendication 1.
Certes, dans le document FR-A-1 556 302, le synchronisme entre le piston et la chambre de compression est assuré par un train d'engrenage situé à l'extérieur de la chambre de comrpession et il n'y a pas de contact mécanique entre le piston et la chambre de compression mais ce dispositif implique un joint d'étanchéité en deux points fixes de la chambre de compression. De tels points fixes n'existent pas avec une forme comprenant deux demi-cylindres parallèlipipédique.
Elle est constituée d'un piston cylindrique à axe de rotation excentrique (3) se déplaçant radialement à l'intérieur d'une chambre de compression (2) dont le volume intérieur est composé de deux demi-cylindres à chaque extrémité d'un volume parallèlipipédique rectangle ; elle-même en rotation à la moitié de la vitesse de rotation du piston.
Le déplacement s'effectue sans contact mécanique entre le piston et la chambre de compression.
La synchronisation du piston et de la chambre de compression est assurée par un train d'engrenages (4) situé à l'extérieur de la chambre de compression.
L'ensemble piston, chambre de compression, train d'engrenages est contenu dans un carter (1) muni à une extrémité de deux lumières (5).
Les lumières sont alternativement ouvertes ou fermées en fonction de la position relative du piston par rapport à la chambre de compression.
La machine peut être constituée d'un ou plusieurs étages sur le même principe.
De cette invention découlent les principaux avantages suivants :
  • Déplacement du ou des pistons dans tout le volume de la chambre permettant d'obtenir un rapport de compression important pour un volume et un poids faible par rapport à la puissance.
  • Sans contact mécanique entre le piston et la chambre de compression ce qui permet un fonctionnement sans lubrification des parties.
  • Peu de pièces
  • Usinage simple
  • Simplicité de montage et de mise en service
  • Maintenance réduite en raison de la faible vitesse relative entre le ou les pistons et la chambre de compression, l'absence de clapets, d'embiellage et de circuit de lubrification.

Claims (4)

  1. Machine tournante volumétrique pour fluide liquide ou gazeux, pompe, compresseur, moteur constituée d'un piston cylindrique à axe de rotation excentrique (3) se déplaçant radialement à l'intérieur d'une chambre de compression (2) mono ou bi-étagée dont le volume intérieur est composé de deux demi-cylindres à chaque extrémité d'un volume parallèlipipédique rectangle ; elle-même en rotation à la moitié de la vitesse de rotation du piston caractérisée en ce que le synchronisme entre le piston (3) et la chambre de compression (2) est assuré par un train d'engrenages (4) situé à l'extérieur de la chambre de compression pour assurer un déplacement des dites pièces sans contact mécanique entre le piston (3) et la chambre de compression (2).
  2. Machine tournante selon la revendication (1) caractérisée en ce que l'ensemble piston (3), chambre de compression (2), train d'engrenage (4) est contenu dans un carter (1) muni à une extrémité de deux lumières (5) alternativement ouvertes ou fermées en fonction de la position relative du piston (3) par rapport à la chambre de compression (2)
  3. Machine tournante selon la revendication (1) ou (2) caractérisée en ce que l'absence de contact mécanique entre le piston (3) et la chambre de compression (2) fait qu'il n'y a pas besoin de lubrification entre les deux pièces.
  4. Machine tournante selon la revendication (2) ou (3) caractérisée en ce que les deux lumières (5) situées à une extrémité du carter (1) permettent l'aspiration et le refoulement du fluide sans clapet ni embiellage.
