Convertible top compartment cover cylinder

The convertible top compartment cover cylinders are charged with pressure at the rebound stage via the energized solenoid valve F2.

They are retracted and in this way, the convertible top compartment cover is closed.

The hydraulic oil displaced from the pressure stage is directed into the hydraulic oil reservoir via F1.

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 cylinders remain run out and ensure the convertible top remains in forward position.

Bracket cylinder

The two-way valve W1 is charged with pressure simultaneously from both sides.

In this way, it is interconnected and the hydraulic pressure is directed to the bracket cylinder rebound stages.

The flow to the cylinder pressure stages is blocked by check valve S1 active on one side.

Through this, the bracket cylinders remain retracted and the bracket is raised.
