Valve device with a flow device
2012
The invention relates to a valve device having at least one inlet area (P) and a first and second outlet area (A, T), which on two interconnected seat valves (23, 24) are connectable fluidically to each other, through the first seat valve (23), a fluid inlet of the inlet area (P) to the first and second flow area (a, T) is adjustable and by the second seat valve (24), a fluid flow between the first and second drain region (a, T) is adjustable and the second seat valve (24) poppet is formed with a cone-shaped closure member (241). Upstream of the disposed between the first and the second drain region (A, T) the second poppet valve (24) a flow guide means (28) is in this case arranged, which is constructed so that this flowing the in the direction of the second seat valve (24) fluid in a swirl added. Here, a taper angle, the closing body (241) of the second seat valve (24) (GAMMA) of 60 ° +/- 10 °.
