Switch actuatable operating system for folding top hydraulic drive elements

An operating system for hydraulic drive elements of a convertible folding top system actuatable by switching devices, comprising drive elements feedable by a pressure source from a pressure medium reservoir via an inlet and connectable to a return to the pressure medium reservoir, switchable directional control valves for distributing pressure generated by the pressure source to the drive elements for moving various parts of the convertible folding top system and having an actuation of the directional control valves corresponding to a given sequence of movements thereof, limit switches configured for actuating the directional control valves, and being positively operated by driven parts, and a plurality of driven parts comprising closures adapted to be locked and unlocked by double-acting working cylinders and mechanically arrested in a release position thereof against locking by an associated working cylinder, wherein the pressure source has a feed line arranged to be constantly flow-connected via inlet lines to a rod side of the working cylinders interacting with the closures, as a result of which a pressurization of the pressure medium in the feed line results in an impingement of the working cylinders in a locking advancement direction thereof, and the working cylinders are configured to be differentially actuatable by assigned ones of the directional control valves so as to switch a drive element of another driven part.
