Abstract
A longitudinally extending housing contains an element for filtering a liquid and an element for heating the liquid. The housing is internally divided into a longitudinally extending generally cylindrical outer chamber, containing the filter element, and a similarly extending cylindrical inner chamber, containing the heating element. The flow of filtered liquid from the outer chamber to the inner chamber is permitted only by having the liquid flow over a generally cylindrical wall defining a weir, which divides the housing into the two chambers. The weir cooperates with a specially formed conical configuration on an end of the housing to define a liquid flow path between the chambers in which undissolved air may be removed from the housing. After entering the inner chamber the filtered liquid flows along the length of the axially directed heating element and the heated and filtered liquid is thereafter discharged from the housing.
