DUAL PRESSURE SPRAY ARM ASSEMBLY WITH DIVERTER VALVE

摘要

A pivotable, dual pressure spray arm assembly (109) has at least one high pressure nozzle (127) and at least one low pressure nozzle (125). The spray arm (109) is pivotably or rotatably attached to a movable gantry (103) via a mounting platform (139). A single fluid conduit (132) transports fluid through the mount (139) to the spray arm (109). A diverter valve (135) mounted on the spray arm (109) includes an inlet (151) configured to alternately receive a high-pressure fluid and a low-pressure fluid from the single fluid conduit, a first outlet (147) configured to distribute the high-pressure fluid to the high pressure nozzles (127), and a second outlet (145) configured to distribute the low-pressure fluid to the low pressure nozzles (125). The diverter valve (135) automatically switches fluid flow between the first and second outlets (147, 145) in response to the fluid pressure received at the inlet (151).
