Definitions

  • the present invention relates to a rotary piston rotary machine.
  • the machine can be used as:
  • It consists of a cylindrical piston with an eccentric axis of 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 rectangle wall; itself in rotation at half the speed of rotation of the piston.
  • the piston, compression chamber, gear train assembly is contained in a casing (1) provided at one end with two slots (5).
  • the lights are alternately open or closed depending on 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

MACHINE VOLUMETRIQUE A PISTON ROTATIF
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
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 parai lèlipipédique 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 pi èces
- 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.
