An adjustment device for exterior hydraulic adjustments, especially those vertically adjacent to tables, beds or work benches and the like, where these are supported by hydraulically or pneumatically activated columns with a carriage cylinder in each leg. The carriage cylinders are connected together via mutual contact with a control housing (5). An adjustment chamber (7) is connected to a pump (12) and a back valve (11). When hydraulic fluid is inserted from the pump, the piston (15) pushes out. This movement is transferred to the carriage cylinders' pistons (13 and 14) by the yoke (21), whereby the hydraulic fluid is pressed out to the carriage cylinders in each column leg.<IMAGE> |
