Abstract:
A pressure control valve device with at least one inlet area and first and second outlet areas which can be connected by two poppet valves. A flow guide device (21), with inflow and outflow areas (22, 23) for guiding the fluid flowing from the inlet area in a defined manner in the direction of the second poppet valve, is located upstream of the second poppet valve, between the first and second outlet areas. The fluid in the flow guide device (21) passes in the area between the inflow and outflow areas (22, 23) through a plurality of channel areas distributed around the periphery of the flow guide device (21) and separated from one another, which are shaped at least approximately helically and impart an at least approximately vortex-like flow pattern to the fluid flowing in the direction of the second poppet valve downstream of the outflow area (23).
