Abstract

Valveless single or multistage reversible positive displacement machine for fluids comprising a rotary piston. The invention concerns a rotary piston assembly with an eccentric rotational axis (3) moving radially within a compression chamber (2), the inner volume being composed of two half-cylinders at each end of a parallelipiped rectangle rotating at half the rotational speed of the piston. There is no mechanical contact, between the rotary piston and the combustion chamber. Synchronisation is provided by means of gear drive (5). The piston, compression chamber and drive assembly is enclosed in a housing (1) with, at one end, two ports (5) for fluid intake and discharge alternately opening or closing according to the position of the piston in relation to the chamber. The machine can be used as a fluid compressor, motor, or fluid pump.

Description

MACHINE VOLUMETRIQUE A PISTON ROTATIF VOLUMETRIC MACHINE WITH ROTARY PISTON
La présente invention concerne une machine tournante à piston rotatif.The present invention relates to a rotary piston rotary machine.
La machine peut être utilisée comme :The machine can be used as:
- Compresseur volumétrique de fluide liquide ou gazeux - Moteur hydraulique ou pneumatique- Volumetric compressor for liquid or gaseous fluid - Hydraulic or pneumatic motor
- Pompe volumétrique de fluide liquide ou gazeux- Volumetric pump of liquid or gaseous fluid
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.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.
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.The movement takes place without mechanical contact between the piston and the compression chamber. Synchronization of the piston and the compression chamber is ensured by a gear train (4) located outside the compression chamber.
L'ensemble piston, chambre de compression, train d'engrenages est contenu dans un carter (1) muni à une extrémité de deux lumières (5).The piston, compression chamber, gear train assembly is contained in a casing (1) provided at one end with two slots (5).
Les lumières sont alternativement ouvertes ou fermées en fonction de la position relative du piston par rapport à la chambre de compression.The lights are alternately open or closed depending on the relative position of the piston relative to the compression chamber.
La machine peut être constituée d'un ou plusieurs étages sur le même principe.The machine can consist of one or more stages on the same principle.
De cette invention découlent les principaux avantages suivants :The main advantages of this invention are as follows:
- 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.- Displacement of the piston (s) throughout the volume of the chamber making it possible to obtain a high compression ratio for a volume and a low weight compared to the power.
- Sans contact mécanique entre le piston et la chambre de compression ce qui permet un fonctionnement sans lubrification des parties. - Peu de pi èces- Without mechanical contact between the piston and the compression chamber which allows operation without lubrication of the parts. - Few coins
- Usinage simple- Simple machining
- Simplicité de montage et de mise en service- Simple assembly and commissioning
- 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. - Reduced maintenance due to the low relative speed between the piston (s) and the compression chamber, the absence of valves, crankshaft and lubrication circuit.
