Abstract

A compartment confining construction comprises an opening and a closure unit movably mounted on the compartment confining construction for movement between a closing position and a fully opened position with respect to the opening. A fluid-based positioning unit is connected to both the compartment confining construction and the closure unit, the fluid-based positioning unit having two working chambers interconnected by at least one flow path, a movement of the closure unit corresponding to a flow of fluid from one chamber to another through the at least one flow path. A fluid flow control device is provided for controlling the flow of fluid through the at least one flow path and thereby controlling the movement of the closure unit. The fluid flow control device is actuatable by an electric actuating device. The flow of liquid occurs in response to movement of the closure unit when the closure unit is moved by an external force.
