ABSTRACT:
For use in gas meters and the like, an improved sliding valve assembly constructed so as to be capable of self restoring the relative sliding motion between a sliding valve and its valve seat when a viscous foreign material tending to accumulate on the valving surfaces inhibits the normal motion of the valve, and thereby insuring a more accurate and reliable metering of a fluid material.
