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.

Claims (4)
- Volumetrische Drehmaschine für flussiges oder gasformiges Medium Pumpe Verdichter, Motor bestehend aus einem zylindrischen Kolben mit exzentrischer Rotationsachse (3), der sich radial im Innern einer ein- oder zweistufigen Verdichterkammer (2) bewegt, deren Innenraum aus zwei Halbzylindern an jedem Ende eines rechteckigen parallelepipedischen Raums zusammengesetzt ist, welche selbst mit der halben Rotationsgeschwindigkeit des Kolbens rotiert, gekennzeichnet dadurch, daß der Synchronlauf zwischen dem Kolben (3) und der Verdichterkammer (2) von einem Getriebe (4) gewährleistet wird das sich im Innern der Verdichterkammer befindet, um die Verschiebung der besagen Teile ohne mechanischen Kontakt zwischen dem Kolben (3) und der verdichterkammer (2) zu gewährleisten.
- Drehmaschine nach Anspruch (1), gekennzeichnet dadurch, daß sich die Einheit Kolben (3), Verdichterkammer (2), Getriebe (4) in einem Gehäuse (1) befindet, das an einem Ende mit zwei wechselseitig, in Abhängigkeit von der betreffenden Position des Kolbens (3) in Bezug zur Verdichterkammer (2) geöffneten oder geschlossenen Öffnungen (5) ausgestaltet ist.
- Drehmaschine nach Anspruch (1) und (2), gekennzeichnet dadurch, daß wegen fehlendem mechanischen Kontakt zwischen dem Kolben (3) und der Verdichterkammer (2) keine Schmierung zwischen den zwei Teilen notwendig ist,
- Drehmaschine nach Anspruch (2) und (3), gekennzeichnet dadurch daß die zwei Öffnungen (5), die sich an einem Ende des Gehäuses (1) befinden, das Ansaugen und Ausstoßen des Mediums ohne Klappe bzw. Pleul ermöglichen.
