Convertible top compartment cover cylinder 

The convertible top compartment cover cylinder rebound stages are charged with pressure via the energized solenoid valve F2. In this way, the convertible top compartment cover remains in closed position.

Main cylinder 

Solenoid valves F2 and F3 are energized.

In this way, the main cylinder pressure stage and rebound stage are charged with pressure.

The pressure is evenly distributed to the cylinder rebound and pressure stages.

Because the pressure stage has the larger piston surfaces in comparison to the rebound stage, different forces can be generated with the same pressure ratios. The force acts on the pressure stage, whereby the cylinder moves out to the end stop and remains there. The convertible top remains tilted forward.

Bracket cylinder 

Both bracket cylinders are activated by solenoid valve F3 during the rebound stage and raise the bracket.

Because it is activated simultaneously from both sides, the two-way valve W1 is permeable in the direction of the bracket cylinder rebound stage. Flow to the cylinder pressure stages is blocked by a check valve active on one side.

Through this, the bracket cylinders are retracted and the bracket is raised. Hydraulic oil displaced in the pressure stages is transferred into the hydraulic reservoir.
