This patent describes a dual-position continuous flow valve assembly. This assembly consists of (a) a first valve member, including (1) a first generally cylindrical hollow housing defining a chamber, the first housing being open at one end and including diametrically opposed inlet and outlet openings adjacent the closed end thereof; (2) first piston means slidably mounted within the first housing for axial displacement between a first position wherein the first piston means is spaced from the first housing closed end beyond the inlet and outlet openings and a second position. The first piston means is adjacent the first housing closed end before the inlet and outlet openings. The first piston includes a generally planar stem portion extending diametrically across the chamber and toward the first housing open end to bisect the chamber into first and second flow passages. The first piston when in the first position affords fluid communication between the inlet and outlet openings when in the second position affords fluid, communication between the inlet opening and the first flow passage and between the second flow passage and the outlet opening occurs and (3) first spring means is arranged within the chamber for biasing the first piston means toward the first position. A system for heating the cooling fluid of an internal combustion engine, is also described.
