ABSTRACT:
A fluid motor is disclosed which includes a rotor supported for rotation about a generally horizontal axis by a hollow shaft. The rotor defines a plurality of chambers circumferentially spaced apart relative to the axis. A relatively large area flow passage extends from the trailing wall portion of each chamber to a succeeding chamber to enable fluid flow between said chambers in a direction opposite to the direction of rotation of the rotor. A relatively dense working fluid partially occupies the rotor. Intake valving introduces a motive fluid into the rotor chambers disposed within a predetermined angular range relative to the axis so that the motive fluid displaces the working fluid from those chambers through associated respective flow passages and in so doing drives the rotor. Exhaust valving communicates with successive rotor chambers disposed in a second angular range relative to the axis for enabling motive fluid to exhaust from the chambers.
