A fluid driving or fluid driven machine includes an outer cylinder housing a stationary piston. The piston includes a generally annular flexible band of smaller circumference than the inner circumference of the cylinder, and a rotary body accommodated within the band. The rotary body has three rollers for urging the band against the inner surface of the cylinder at three angularly spaced locations so that the band defines with the cylinder three working chambers. Two separating members mounted on the cylinder are biased into contact with the band. When t...
In a fluid-flow machine means defining a cylinder having an internal cylidrical surface and ports in that surface respectively for the admission and exhaust of fluid, an assembly mounted within the cylinder including two opposed, interconnected, parts, together rotatable relatively to the cylinder, each part having a peripheral surface with complementary curvature to that of the internal cylindrical surface of the cylinder and having the same centre as that of the cylinder, means biasing the said parts towards the cylinder wall, and a flexible ring inter...
