HAND GRINDER AND VALVE THEREFOR

HAND GRINDER AND VALVE THEREFOR A valve comprises a displaceable valve body which can abut on a valve seat and limit the flow of a medium. The valve has a valve casing which is closed at one end and which has an inlet for the medium at said end. A stem which carries a valve body extends from the other end of the casing. The valve body co-operates with a valve seat designed as a shoulder in a bush through which the stem can be axially displaced.
