Magnetic valve

摘要

The invention relates to a magnetic valve assembly of the type in which a solenoid plunger upon excitation by a magnetic coil is displaceable against a housing end face having a valve seat. The plunger has a bore in which is disposed a closing element. A return spring in the plunger bore biasing the plunger away from the valve seat is between the far end of the plunger and a fixed abutment element which passes through the plunger. The plunger has a hole surrounding the abutment element which is sized to allow the plunger engage the valve seat and to limit the movement of the plunger away from the valve seat.
