Convertible top compartment cover cylinder

The convertible top compartment cover cylinders are not activated.

The check valve contained within comes into use through the energized solenoid valve F1. This prevents the cylinder from becoming depressurized in the pressure stage and the convertible top compartment cover from being closed.

Main cylinder

The hydraulic pressure is channeled directly to the main cylinder pressure stages via check valve S1.

These remain run out and hold the convertible top in forward position.

The hydraulic pressure cannot vent in the system through two-way valve S1 and energized solenoid valve F3.

Bracket cylinder

Both bracket cylinders are directly charged with pressure via the pressure stage.

They are run out and the bracket is stored in the convertible top compartment.

In the rebound stage, displaced hydraulic oil is directed in the system and discharged into the hydraulic oil reservoir via F2.
