Abstract
A microsprayer producing a pressure compensating jet is disclosed comprising a substantially cylindrical housing open at a first end thereof and having a spray directing boss formed integrally therewith and adjacent to a second and opposite end thereof; and an insert body adapted to be press fitted within the housing and comprising a longitudinally directed wall portion, first and second flanges extending respectively from opposite sides of the wall portion so as to bear sealingly against an inner surface of the housing so as to define therewith respective inlet and outlet chambers. A flexible membrane is located in the inlet chamber so as to divide it into first and second sub-chambers and a water inlet means is formed in a first end wall of the insert body adjacent the first end of the housing and communicating with the first sub-chamber. A communicating aperture formed in the wall portion serves to effect communication between the second sub-chamber and the outlet chamber, there being a second end wall of the insert body adjacent the second end of the housing and formed with a spray outlet aligned with and adjacent to the spray directing boss.
