A pulsating fluid nozzle is disclosed which comprises a body having an inner chamber and an outer chamber separated by a cylindrical wall. The inner chamber is supplied with fluid through a fluid outlet, and the outer chamber supplies fluid to the fluid outlets. The cylindrical wall has a port through which fluid can flow from the inner chamber to the outer chamber. A rotor is mounted for rotation in the outer chamber. The rotor has a blade extending from an annular hub which is adapted to fit around the cylindrical wall and block the flow of fluid through the port. The hub has an opening adapted to intermittently coincide with the port as the rotor turns to permit the flow of fluid through the port to produce a pulsating flow. The blade is adjacent to the opening and positioned to be contacted by a stream of fluid flowing through the port when the opening coincides with the port. The contact by the stream of fluid propels the blade to turn the rotor. The nozzle produces a pulsating flow without using a special pulsating pump, and can utilize the full maximum flow of fluid through the flexible hose connected to the fluid inlet of the nozzle.

Pulsating nozzle

Apparatus is disclosed for cleaning a sewer or other chamber. The apparatus includes a wheeled vehicle having a frame. A water reservoir tank is mounted near the front of the vehicle frame and is adapted to hold a supply of water. A hose unit is mounted at the rear of the vehicle frame. The hose unit has a hose connected to the water reservoir tank and adapted to be inserted into the chamber to discharge water into the chamber. A debris holding tank is mounted on the vehicle frame between the water reservoir tank and the hose unit. The debris holding tank is adapted to receive and hold debris. A boom is mounted on top of the debris holding tank and adapted to extend rearwardly over the hose unit. The boom has a conduit connected to the debris holding tank and adapted to be lowered into the chamber to be cleaned to transport material from the chamber into the debris holding tank. The location of the debris holding tank amid the water reservoir tank and the hose unit permits the boom to extend over the hose unit and be used in conjunction with the hose paid out from the hose reel. The position of the tanks also permits an even weight distribution on the vehicle frame.
