Abstract
A rotating spray nozzle for use in cleaning containers having a spray head on a shaft, an element for passing liquid both to the exterior of the spray head to cause rotation thereof and for the delivery of liquid in annular streams, liquid passing to the spray head through the shaft and having an hydraulic bearing therefor, the liquid after passing from the spray head occupying which would be a void as far as washing is concerned. The spray head is also moveable axially relative to the shaft, a spring holding the spray head away from the bottom of the shaft when there is no pressure passing therethrough, the pressure of the liquid moving the spray head to the bottom of the shaft, the arrangement providing a manner whereby foreign material can be removed from between the spray head and the shaft as, by reducing the pressure, the space between these can be increased, thus permitting ready flushing of the foreign material. Flushing can be facilitated by liquid passing between the shaft and the spray head and liquid can be disseminated beneath the spray head by a liquid stream which is at an angle to the axis of the nozzle.
