A hydraulically or pneumatically operated pendulum piston or ring piston engine, comprising a cylinder housing (1) having a toroid shaped cylinder race (2, 3), in which a pendulum piston means (6-8) is rotatable in two opposed rotary directions, and in which the cylinder race, at a place thereof is divided by a piston chamber wall having pressure supply means (15), and in which the pendulum piston means (6-8) is integral with a fly mass (9) which is connected to a central, output shaft (11), and in which the toroid shaped cylinder race (2, 3) is formed with two opposed, closed cylinder chambers (2, 3) each extending over nearly 120 DEG , and in which the pendulum piston means include two pistons (6, 7) which are integral over a bow formed piston rod (8) extending over an angle of about 240 DEG , and which piston rod (8) at an intermediate position between said pistons (6, 7) is controlled by and connected to (10) the output shaft (11) over the fly mass (9), and in which the fly mass (9) is connected to a reversing mechanism (19) for providing a reversing of functional operation of the output shaft (11) when the pendulum piston means (6-8) changes rotary direction, so that the output shaft (11) constantly rotates in one and the same direction. |
