Spinning wash nozzle assembly

Image Number 7 for United States Patent #6209802.

A spinning wash nozzle assembly having a fluid brake pump within the rotating spinner housing. The fluid pump has a sump which is also within the rotating spinner housing such that centrifical forces acting on the fluid tend to separate the heavier fluid from any air within the sump. As a result, only the fluid is drawn into the pump as opposed to fluid and air. This avoids undesirable effects on the pump from air being drawn therein.
