Abstract

A diverter valve for conveying a material has a housing with at least three passage openings for feeding or discharging material. The passage openings define a conveying plane. The diverter valve includes a rotary part with an outer contour that is conical, at least in sections, with respect to its axis of rotation. The rotary part is arranged in a sealed manner in the housing. The rotary part can be axially displaced and rotated within the housing. The axis of rotation is perpendicular to the conveying plane. A passage conduit is arranged in the rotary part, which, depending on the rotational position of the rotary part, connects to each other two passage openings for conveying material along the passage conduit through the diverter valve. A drain opening is provided in the housing for the automatic drainage of a liquid from the housing.
