Abstract
A solenoid valve useful in a slip-controlled hydraulic brake system of a motor vehicle, and which has a seat valve disposed between a pressure fluid inlet and a pressure fluid outlet and in the bypass to this seat valve, has a check valve with a hollow conical valve seat and a closing body, which has a section that is embodied as complementary to the hollow conical valve seat. A rubber-elastic sealing ring is accommodated with the greater portion of its cross section in the circumference of the section and in the closed position of the check valve, this sealing ring can compensate for dimensional deviations of the valve seat at low pressures.
