Abstract

1509714 Fluid-pressure actuators FESTOMASCHINENFABRIK GOTTLIEB STOLL 17 June 1975 [2 July 1974] 25801/75 Heading F1D In a fluid-pressure operated actuator, Fig. 1, the piston 4 and piston-rod 5 are hollow and are formed in one piece by a chipless process. As shown the wall thickness is uniform. Metal or synthetic material may be used and manufacture may be by moulding, casting, extrusion, drawing or pressing, Fig. 2 (not shown), illustrates a second embodiment.
