Abstract
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°.
