Abstract

Improved piston for oil-free toroidal compressors, in which the piston provided with its corresponding rings, preferably tetrafluoroethylene, has a pendular displacement inside a toroidal cylinder, characterized in that an O-ring is arranged between the bottom of each groove and the corresponding ring. Of elastic material that constantly drives the hoop pressing it against the surface of the cylinder, because from the bottom of the groove emerges in the radial direction, at least, a python that fixes the position of the corresponding hoop, avoiding its rotation in relation to the piston and because less in the area corresponding to the ends of the ring an air retaining pad is provided.
