OIL FILTER Russian patent published in 2005 - IPC

FIELD: automotive industry.

SUBSTANCE: invention is designed for cleaning oil in automobile engines and engines of other vehicles. Proposed filter has housing, cover with reinforcement connected by rolling down. Housing accommodates filtering element, antidrain and bypass valves and spring. Antidrain valve is made in form of cup with flat and cylindrical parts. Flat part provides sealing of end face surface of filtering element and reinforcement, and cylindrical part is made in form of lobe whose sealing edge provided with ring thickening tightly fits to inner surface of cover. Reinforcement is provided with cutouts on periphery to pass oil. Such design precludes passing of oil in cover-reinforcement joint without additional sealing devices and decreases overall dimensions of filter without impairing its filtering properties.

EFFECT: reduced metal usage, facilitated assembling.
