<p>Both sides of the swivel cylinder (2) which is used to turn the indexing table are each connected by a line (3, 4) to the outlet of a three-way pressure regulating valve (7, 8) whose inlets are connected via lines (5, 6) to a pressure source (9). The valves each have a servo valve (10, 11) whose inlet is coupled to the pressure source (9). The outlet of one servo valve (10) is connected to a routing valve (14) for the lift cylinder (1). Control connections (12, 13) for both three-way valves (7, 8) are joined to the operating lines (17, 18) of the cylinder (1).</p> |
