Abstract
A convertible top operating mechanism includes a bi-directional hydraulic pump which is selectively connected to top-operating hydraulic cylinders and tonneau-operating hydraulic cylinders by a two-way, 5-condition control valve to selectively raise and lower the top and tonneau. A mechanical linkage connects the top-operating cylinders with a movable rear bow and is co-operable with a spring during operation of the top-operating cylinders when fully extending and initially retracting to move the rear bow to enable tonneau operation and to seal the top on the tonneau.
