Abstract

1494977 Fluid-pressure servomotor systems HYDRAULIK BRATTVAAG AS 10 May 1976 [20 Mayl975] 19088/76 Heading G3P A slide valve (not shown) is durably connected to a handle 28 for direct manual operation of the valve and to a servomotor control system through a rotatable lever 70a connected to the valve and a pair of actuating members 80 which on operation of said control system are selectively advanced into the path of movement of the lever 70a so as to rotate the lever 70a and so actuate the valve. The members 80 are carried by cup shaped members 79 which are urged apart by a spring 74. The servomotor control system comprises a pair of slide valves (37a, 37b), Fig 2, (not shown) which are selectively moved by a manually operated rocker (48) to connect either a conduit 41 or a conduit 42 to a pressure supply line. The conduits 41, 42 connect with passages in the casing 76 which houses the members 79, so that pressure is selectively applied to one of two pistons 78 attached to the members 79 in order to advance the associated actuating member 80 against the action of the spring 74. The degree of rotation of said rocker (48) determines the positions of the slide valves (37a, 37b), of the members 79 and hence the position of the main slide valve.
