Proportional pressure control valve with a magnetic part and a valve part, the valve part has an inflow opening for the inflow stream, a first outflow opening for the filling stream, and a second outflow opening for the tank volume stream, and has a ball seat, a flat seat with an opening, a closing part for controlling the throughput quantity through the opening of the flat seat, and a stream diverter. The inflow opening faces away from the magnetic part and coaxially to its longitudinal axis, and the outflow openings are constructed on the side wall of the valve part radially to its longitudinal axis, so that fluid flowing from through the valve is exposed to a diversion of a maximum of 90°. The fluid, after flowing through the ball seat and to and through the stream diverter, experiences a diversion of less than 30°.

The invention claimed is: 1. A proportional pressure-control valve with a magnetic part and a valve part, the valve part being provided with an inflow opening for an inflow volume stream, a first outflow opening for a filling volume stream, and a second outflow opening for a tank volume stream, and comprising a ball seat, a flat seat provided with an opening, a closing part for controlling a throughput quantity through the opening in the flat seat, and a stream diverter, which is positioned between the ball seat and the flat seat, the inflow opening (6) for the inflow volume stream being constructed on a front side end (10) of a valve part facing away from the magnetic part and coaxially with its longitudinal axis, at least one outflow opening (7) for the filling volume stream being constructed in a side wall of the valve part radially to its longitudinal axis, and an axial distance of the stream diverter (5') from the ball seat (4), as well as a diameter, a wall thickness, and a shape of the stream diverter (5') being selected such that fluid particles, after flowing through the ball seat (4) and to and through the stream diverter (5'), are exposed to a diversion of less than 30°; and the stream diverter (5') being provided with a cross drilled hole (15). 2. The proportional pressure control valve according to claim 1, wherein the axial distance of the stream diverter (5') from the ball seat (4) is greater than 1·NW, whereby NW is a diameter of the opening (16) in the flat seat (3). 3. The proportional pressure-control valve according to claim 1, wherein the diameter of the stream diverter (5') is smaller than 1.3·NW, whereby NW is a diameter of the opening (16) in the flat seat (3). 4. The proportional pressure-control valve according to claim 1, wherein the wall thickness of the stream diverter (5') is smaller than 0.15·NW, whereby NW is a diameter of the opening (16) in the flat seat (3). 5. The proportional pressure-control valve according to claim 1, wherein the diameter of the cross drilled hole is greater than 0.5·NW, whereby NW is a diameter of the opening (16) in the flat seat (3). 6. The proportional pressure-control valve according to claim 1, wherein a filter sieve (9', 9,), which has a mesh size is at least 190 μm, is inserted into the inflow opening (6) and into at least one outflow opening (7). 7. The proportional pressure-control valve according to claim 1, wherein a total area of the outflow openings (7) for the filling volume stream is greater than 4·a nominal area, whereby the nominal area is equal to 1·NW2·Π/4, and NW is a diameter of the opening (16) in the flat seat (3).
