A swivel jet assembly 20 for a fluid distribution system delivers high pressure fluid from a pressurized fluid source to an object to be cleaned. A bearing housing 46 is removably affixed to a swivel body 32 having an inlet port 34 and a fluid transmission passageway 36 therethrough. A hollow shaft 40 has an upstream end positioned within the swivel body and a downstream end extending outward for engagement with a nozzle assembly 30. One or more nozzle jets 116, 118 are supported directly within a nozzle housing, and are angled for causing a torque in response to the high pressure discharged from the nozzle jets. A speed control device within the swivel housing includes a plurality of pins 58 each movable radially outward in response to centrifugal force for engagement with the swivel housing. The swivel is of the in line design, and a thrust bearing 66 is provided within the swivel housing upstream from the swivel speed control device. The nozzle assembly is designed for easy service and includes large angle flow distribution passageways for reducing the pressure drop across the nozzle assembly and for producing a desired spray pattern. |
