A polyjet valve has an inlet opening into an inlet chamber normally communicating through a movable polyjet sleeve in variable amounts and in one direction with an outlet chamber having an outlet. There is a block to close the outlet and a conduit to establish backflow from the outlet chamber through the polyjet sleeve in the reverse direction and then to waste.


A valve comprising a body including means defining an inlet chamber disposed about an axis; means defining an outlet chamber disposed about said axis and adapted to communicate with said inlet chamber; a cylindrical polyjet sleeve disposed between said chambers and extending along said axis and having a plurality of radially extending, circumferentially arranged, axially spaced discrete openings therethrough and adapted to communicate with said inlet chamber and said outlet chamber, each of said openings having a predetermined axial length; a ring coaxia...
