Abstract
A device comprising at least one cylinder in which a piston-like first body is adapted to move to vary the volume of a work space, the seal being formed between said first piston-like body and the cylinder wall by at least one rolling diaphragm, having at least one side in contact with a liquid, said device comprising means for maintaining, on each of the rolling diaphragms, a pressure difference that is substantially constant at least during each stroke, the first being piston-like body, on its side away from the working space in contact with a liquid which, in turn, is in contact with a second piston-like body coupled with a drive mechanism, characterized in that the diaphragm side rolling that faces the second piston-like body is also in contact with said liquid disposed between the two bodies in the manner of pistons and elastic members are applied to the first body as a piston to maintain a pressure difference on said body and because the device comprises means for compensating the forces of inertia of the first body in the manner of a piston plus, as the case may be, the forces of inertia of a quantity of liquid substantially corresponding to the volume of the space limited by the side of the first piston-like body in contact with the liquid and the tangential plane of the rolling diaphragm at right angles to the centerline of the device in the central position of the piston-shaped bodies in such a measure that said forces do not substantially affect the difference in pressure on the rolling diaphragm and the first body in the manner of a piston.
