Multiple channel pipe especially for garden spray head has an extruded construction with separate parallel ducts to connect between a control valve and the spray head

摘要

A multiple channel pipe, e.g. for a garden spray head is made of aluminium extrusion with separate parallel ducts (11) running the whole length of the pipe. The separate ducts can be of any suitable cross section, e.g. hexagonal, radial sectors etc., and connect the control valve to the spray head. Each duct supplies a set number of spray holes and the valve controls the relative flow to each duct. This enables the user to vary the spray pattern without interrupting the spray process and without altering the spray head.
