Abstract
A valve unit includes a positioning device for converting a rotary motion into a linear motion, a valve rod, a drive unit, a drive shaft with an eccentric arranged thereon, a coupling element comprising a slot, and an output shaft arranged at the eccentric which moves in the slot of the coupling element. The valve rod is connected with the coupling element. The valve rod is linearly movable with the coupling element between an initial position where the valve is closed and an end position. The slot comprises a guide path which cooperates with the eccentric having an angle with a plane perpendicular to a direction of movement of the adjusting element. The initial position of the eccentric is a position which is located before a dead center existing for an axial movement of the output shaft. The dead center is passed during a rotational movement of the drive shaft.
