Abstract
A self supporting-one piece resilient metal wire cloth filter having an integral and permanent bypass opening (window), the filter being removably disposed in the inlet duct of an internal combustion engine radiator. The filter can be removed, flushed, and reinstalled to remove foreign particles entrained with the liquid coolant as the latter circulates, thus permitting continued high efficiency of heat transfer from the hot cylinder to the coolant and from the coolant to the radiator core.
Claims1
A filtering device installed in the radiator inlet of an internal combustion engine cooling system comprising a self supporting, hollow, conical, one piece metal wire cloth filter means which has its longitudinal axis disposed parallel to the coolant duct and having an integral bypass consisting of an opening in the uppermost portion of said conical filter means said opening being of a size such that any particle passing through an open thermastat will be captured or bypassed without reducing coolant flow rate in either event even when the filtering surface beocomes clogged in normal operation.
