ABSTRACT:
A drive comprising a rotatably journalled shaft on which a plate is mounted so that the plate cannot rotate with respect to the shaft during operation. The plate can, however, be adjusted around a pin which extends transverse to the rotatably journalled shaft, so that the angle enclosed by the plate and the shaft can be varied. The pin is journalled in a bearing block which is adjustable in the shaft direction. Each of the pistons has a piston rod with a piston rod head whose side which faces the plate is provided with a spherical surface which cooperates with a sliding body which bears against the contact surface of the plate. The side of the plate which is remote from the piston rod comprises a spherical cam which has the same center of curvature as the spherical surface of the drive rod head. The cam is supported by a surface which forms part of a structural member which is rigidly coupled to the shaft.
