Component i.e. modular valve unit, for vehicle door control circuit for controlling opening and/or closing of door of vehicle i.e. bus, has two connection parts connected with pressure chambers and quick exhaust part

摘要

The component (4) has a first connection part (12) connected with a manual control valve (3) and resting against actuating pressure. A vehicle door control circuit (1) comprises pneumatic pressure chambers (6, 7) that are fixed with a pressurized air source (2) e.g. pump, and/or an exhaust part based on operation of the control valve. A quick exhaust valve (20) transfers the pressure at the first connection part into a quick exhaust position. Second and third connection parts (13, 14) are connected with the chambers and a quick exhaust part (23). A control unit includes a control module. The pressure chambers are selected from an aperture chamber and a closing chamber. An independent claim is also included for a vehicle door control circuit for controlling opening and/or closing of a door of a vehicle.
