Pressure-compensated control valve, has seat limiting surface running between valve element and valve piece, where seat limiting surface is limited by seat disposing edge, which is guided at valve element or at valve piece

摘要

The valve has a valve element (12) opening or closing a valve seat (28) that cooperates with a valve piece (22). The valve seat is attached to a high-pressure chamber. The valve piece pressurizes or decompresses the high-pressure chamber. A seat limiting surface (44) at the valve seat runs between the valve element and the valve piece, where the seat limiting surface is limited by a seat disposing edge (40), which is guided at the valve element or at the valve piece. A seat limiting groove represents an interruption of a seat face (30) and a conical surface.
