ROTARY DISK VALVE FOR A FUEL CELL SYSTEM

摘要

The invention relates to a rotary disk valve (14) with a valve housing (19) which has three line openings (20, 21, 22) and a rotary slide (23). The rotary slide (23) has at least one control edge (24) which interacts with the cross section of at least one of the line openings (20, 21, 22) in order to influence a flow of media through said line opening. The invention is characterized in that the rotary slide (14) is designed to be able to close one of the line openings (21) while simultaneously influencing the permeable cross section of the adjacent line opening (22). The rotary disk valve (14) can be used in particular in a fuel cell system (1) which is preferably arranged in a vehicle (2). The invention further relates to a method for starting such a fuel cell system (1).
