1. A valve assembly, comprising: a housing with a first inlet, a second inlet, a first outlet, and a second outlet; wherein a first flow path is provided between the first inlet and the first outlet, a second flow path is provided between the second inlet and the first outlet, and a third flow path is provided between the first inlet and the second outlet; a closure element that is supported in the housing to be movable, the closure element in a by-pass position opens the first flow path and closes at least the second flow path, and in a normal position closes the first flow path and opens the second flow path as well as the third flow path; and a flow guiding element provided on the closure element, which flow guiding element in the normal position of the closure element protrudes into the second flow path and is coupled to the closure element in such a way that the flow guiding element urges, in a gas flow from the second inlet to the first outlet, the closure element into the normal position, and wherein the flow guiding element is implemented as a separate component on the closure element, and wherein the flow guiding element comprises a metal sheet that is attached to the closure element; and wherein the closure element includes first and second flaps circumferentially spaced apart from each other, and wherein the first flap closes the third flow path in the bypass position and the second flap closes the first flow path in the normal position, and wherein the flow guiding element is mounted to the closure element to be positioned at an acute angle relative to the second flap, and wherein the second flap closes the second flow path in the bypass position.
