Abstract:
1. A cooling system for use with an engine, the cooling system comprising: a radiator; a radiator bypass; and a fluid valve in communication with the engine, radiator and radiator bypass, the fluid valve being controllable to proportion coolant from the engine to one or both of the radiator and radiator bypass in order to control engine cooling, the fluid valve including: (i) an axially elongated housing having an inlet for receiving coolant from the engine and separate outlets for outputting coolant to the radiator and radiator bypass, the outlets located at a common face of the housing and the inlet located upstream from the outlets and radially thereto such that the outlets are along the longitudinal axis of the housing and the inlet is along the radial axis of the housing whereby coolant must travel radially and then axially within the housing along a fluid flow path defined from the inlet to the face having the outlets; (ii) a rotary actuated diverter within the fluid flow path and configured to rotate axially about the longitudinal axis of the housing and relative to the face of the housing so as to selectively cover the outlets and thereby proportion fluid flow between the inlet and outlets associated with the radiator and radiator bypass; and (iii) wherein the common face includes grooves below an outer surface that the diverter contacts.
