ABSTRACT:
A mechanical actuating device for hydraulic control valves having complex control functions, which can be assembled from individual units in a modular system, each of which has valve bodies which can be operated by longitudinal displacement in a housing that can be joined to the housing of the adjacent module. The actuating device for each module has a cam control member rotatably mounted in a cam housing which can be placed on the module housing and which can be brought into engagement with the ends of the valve bodies protruding from the module housing. The cam control members of all individual modules are disposed with aligned axes of rotation, and a coupling is provided for the co-rotational joining together of the cam control members of adjacent modules in selectable relative angular positions to one another.
