<p>Hydraulic power transmission device (1) adapted to form part of a control system at which the pressure of a hydraulic fluid (6) is controlled at one or more points of the control system by fluid pressure actuated members and in which changes of the fluid pressure actuate one or more operative members of the control system which device comprises a plurality of tubular expandable bellows (2), which at one end are closed and at the other end are connected to each other by tubes (5) or hoses, the closed space so obtained being filled with hydraulic fluid. The tubular expandable bellows (2) are equipped with tubular guide bushings (9) so that the movements of the bellows (2) are concentrated in axial direction. The bellows (2) are manufactured of metal.</p> |
