<p>The pressure regulated drip feed has a hollow body (1) onto which a hollow cap engages to form a chamber which opens through the base to an inlet, and through the wall of the cap (8) to an outlet. The chamber has a resilient disc to regulate fluid flow, free to move under pressure of the flow. It controls fluid passage through a groove (16) formed in a seat adjacent to the fluid outlet and through a primary groove (19) around the edge of the disc. - The grooves are separated by a recess surrounding the seat, so that differential pressure exists on the disc (18) sides.</p> |
