<p>The specification describes a rotary piston machine having parallel and internal axes, comprising displacement cells which are formed between a stator and a rotor, alternately enlarge and contract between two extreme volumes, and are connected to connections by way of a distributing valve consisting of a valve portion fixed to the stator and a rotary slide that is fixed by a shaft to rotate with the rotor. The rotary slide is adjustable through a limited angle with respect to the rotor by means of an adjusting apparatus-having at least two chambers associated with each connection. A circular piston machine, is particularly described, in which a pinion enclosed by a hollow wheel is connected to the rotary slide by a cardan shaft. A signalling device is provided, which transmits a signal between the instant at which one of the extreme volume displacement cells passes through the neutral position and the instant of the pressure change in this cell as caused by the distributing valve, and the chambers of the adjusting apparatus are connectible to the connections by way of a three-position regulating valve which moves during the period of the signal impulse into its open position effecting shortening of the next impulse.</p> |
