Abstract
An operating arrangement for movable parts on motor vehicles, especially for trunk lids, folding tops and the like, consists of at least one hydraulic cylinder with a piston rod as the driving means which acts on the movable part either directly or indirectly, e.g., via a hinge, and at least one pump arrangement (,through,) mounted on the hydraulic cylinder with a tank, motor, and the like. To create a compact operating arrangement which can be adapted easily and quickly to the given requirements in each case and can also be serviced easily and repaired by replacing individual components, the operating arrangement according to this invention is characterized in that the hydraulic cylinder and the pump arrangement (,through,) are two separate parts combined into one unit by a detachable connection, with at least one direct, tubeless flange connection being provided between the pump arrangement and the hydraulic cylinder connecting the pump to at least one duct in the pump arrangement (,through,) and at least one duct in an end piece of the hydraulic cylinder which leads to one of its working chambers.
