ABSTRACT:
Disclosed is a permanent liquid filter assembly, which includes an oil filter unit made up of an outer housing with inlet and outlet ports and a reconditionable filter material and a bypass valve means for providing a passage way between the inlet and outlet ports, when the differential pressure across the filter means exceeds a certain predetermined value contained therein. The assembly also includes an adapter with multiple inlet and outlet ports, providing fluid communication means between the inlet and outlet ports of the filter and the oil inlet and outlet ports of the engine block to which the filter assembly is attached, as well as inlet and outlet ports for making fluid connections with an external pump device by means of fluid quick disconnet couplers, thereby enabling a flushing fluid to be pumped through the filter element in a reverse direction opposite that of the oil normal flow. This procedure facilitates dislodging and removing contaminant particles from the oil filter material thereby essentially reconditioning the filter means for further continued use, without having to remove the filter. In addition, the adapter configuration of the present invention allows the introduction of fresh engine oil under pressure into the reconditioned filter.
