Abstract
A drive assembly for a flap of a motor vehicle includes at least one motor drive and at least one gas pressure element having a cylinder and a piston. The piston divides the cylinder interior into two partial spaces and has a passage arrangement, through which a balancing flow between the two partial spaces arises when the piston moves. The gas pressure element has a first drive connection point connected to the cylinder and a second drive connection point connected to the piston. A switchable valve assembly is associated with the piston and can be brought into a closed state, in which the valve assembly at least partially closes the passage arrangement, and it has an open state, in which the valve assembly opens the passage arrangement. The passage arrangement automatically switches into the closed state in the event of a balancing flow that exceeds a predefined switching flow.
