Abstract (en)

[origin: WO9928597A1] A hydraulically or pneumatically actuated pendulum piston motor or ring (toroid) piston motor comprising a cylinder housing (1) having a cylinder (toroid) race (2) therein, in which a pendulum piston (3) is swingable in two opposite swing directions, and in which the cylinder race (2), at a place thereof, is divided by a piston chamber wall (4) which defines a piston chamber (5 and 6) on each side of the piston (3), and in which the pendulum piston (3), via a fly mass (10), is connected to a central, output shaft (13) and is arranged to operate over an actuation angle in each swing direction of 340-355 DEG . The pendulum piston motor is formed with two free wheel couplings (14, 15) acting in opposite directions in relation to each other, and with means (17-21) for inverting the direction of rotation of the output shaft (13) during one swing direction of pendulum piston (3).
