Open cellular pump filter element for homogenization of air-oil mixtures
This patent describes an open cellular dispersion element interposed between an oil filter and an oil pump of an automatic transmission communicating with a source of oil. The process comprises an oil filter including a filter housing having means defining an inlet communicating with the source of oil and means defining an outlet communicating with a suction fluid passage leading to the oil pump and a filter screen in the housing dividing the filter into an inlet chamber and an outlet chamber. The improvement comprises an open cellular dispersion element substantially completely filling the outlet chamber to break up large air bubbles forming in the filter housing and homogenize the air/oil mixture prior to entering the pump.
