Definitions
- 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.
- the technology is of the compressor or vane pump type.
- the 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
- the machine figure 1 is composed of:
- 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.
- 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.
- An orifice (6) allows the fluid to enter the compressor, it is sucked by the volume variation generated between each pallet during rotation.
- 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).
