摘要:
A pressure control valve in which the mass to be moved by the diaphragm is reduced by providing that a valve seat body having a valve seat face is placed in a middle region of the diaphragm. When the valve seat face lifts away from the valve closing body, fuel to be diverted flows from the pressure control side of the diaphragm to the return side of the diaphragm, via the valve seat face and a return conduit The pressure control valve is especially suitable for use in fuel supply systems of internal combustion engines.
