A rotary engine or pump employs a block or housing having a cylindrical cavity along the axis of which extends a cylindrical drive shaft supported on the block to permit rotation thereof. Within the cavity, parallel edge walls axially spaced apart from one another and rotatable relative to the shaft and the cavity define between them the bounds of energy chambers. Between these parallel edge walls are arranged an even number of outwardly directed imperforate movable walls with alternate movable walls being attached to and moving with one of the edge walls and intermediate movable walls being attached to and moving with the other edge wall, such that the edge walls and movable walls, the drive shaft and the cavity walls of the block form a plurality of essentially separate and non-intercommunicating energy chambers between the movable walls. The movable walls of the energy chambers are rotatable about the axis of the shaft and rotate with and, in fact, drive the shaft. Inlet and outlet port means through said block are circumferentially spaced around the circumference of the cylindrical cavity to respectively admit fluid into the successive energy chambers which pass the inlet port means as the movable walls move apart and exhaust fluid from the successive energy chambers which pass the outlet port means as the movable walls close together. The oscillation movement of the walls with respect to the shaft is translated into rotational movement of a planet gear on a radial arm fixed to the drive shaft and driving the arm and the shaft, in turn, by its progressive rotation about a sun gear fixed to the block.
