A rotary engine, which is capable of operating as a pump, a compressor or a fluid-driven motor, comprises a casing 1 defining an annular chamber 8' containing a radial vane 2 that is attached to a rotor 2' carried by a driving, or power-output, shaft 13, which also carries externally of the casing a ring 26 whereon pairs of projections 11, 12 and 6, 7 are mounted so as to periodically actuate two diametrally-opposed pairs of rotary valve-members 8k, 81, 8m, 8n and two diametrallyopposed rockable-abutments 3x, 3y for the vane, respectively, when the rotor rotates. Each of the valve-members is coupled by a shaft 32 to a cruciform armature 9 carrying a roller 10 on each of its arms and each of the abutments is coupled by a shaft 31 to a pair of arms 33 carrying rollers 5. When the engine is operated as a motor the abutment 3x is in a closed position while working- fluid is fed into the chamber 8' past the valvemember 8k by way of a conduit 36 so as to drive the vane 2 in an anti-clockwise direction according to Fig. 1., the abutment 3y being in an open position while the valve-members 8l, 8n are in a closed position and the valve-member 8m is in an open position to permit discharge of spent working- fluid from said chamber. As the vane approaches the valve-member 8m, one of the adjacent projections 11, 12 engages with one of the rollers 10 to move this valve-member to a closed position while the valve-member 8l is moved to an open position by a similar action, the abutment 3y being moved to an open position by one of the projections 6, 7 while the other abutment is moved to a closed position by a corresponding action. Working-fluid then enters the chamber 8' past the valve-member 8m while spent working-fluid is ejected past the valve-member 8l as the vane undergoes further displacement in an anti-clockwise direction. During the remainder of the revolution of the rotor the valve-members and the abutments undergo a similar sequence of operations. The projections 6, 7, 11, 12 are secured to the ring 26 by bolts 29 engaging with arcuate slots 28 in the ring that are of sufficient length to permit adjustment of the circumferential positions of the projections. In an alternative embodiment, Fig. 3 (not shown), inlet passages 18, 21 for working-fluid are controlled by abutments (3a, 3b), which are similar to the abutments 3x, 3y, outlet passages (19, 20) being controlled by valve-members 8a, 8b that are similar to the valve-members in the embodiment according to Figs. 1 and 2. The engine may include more than one radial vane on the rotor.
