Abstract

A valve device having at least one inflow area and first and second outflow areas, which are connected with one another with regard to the flow through two poppet valves. Through the first poppet valve, a fluid inflow from the inflow area to the first and second outflow areas can be adjusted and a fluid outflow, through the second poppet valve between the first and the second outflow areas can be adjusted. The second poppet valve is designed as a cone poppet valve with a cone shaped closure body. Located upstream of the second poppet valve, between the first and the second outflow area, is a flow guide device which is designed to provide the fluid, which flows in the direction of the second poppet valve, with a swirl. The closure body of the second poppet valve has a cone angle of 60°+/−10°.
