ABSTRACT:
A self-flushing irrigating valve formed, at least in part, of an elastically deformable material which, when subjected to differential pressures below a preselected value, occupies an open position forming a passage for the flushing of water therethrough; and when subjected to differential pressures above a preselected value, forms a constricted passage for trickle flow of water therethrough. The valve, when in its trickle flow condition, tends to effect further constriction on further increase in differential pressure thereby tending to produce a uniform flow rate through a range of effective pressures.
