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.

Drive for a machine comprising variable-stroke reciprocating pistons

A hot-gas engine comprising an engine part which is provided with a blanket of ceramic fibres in order to provide protection against high flame temperatures of the burner. The blanket is anchored to the engine part by means of lugs which are bent around metal wires arranged between the fibres.
