Abstract
A filter for fluids has a chamber into which fluid is fed in such manner that it forms a vortex. Particulate matter tends to collect at the center of the vortex, leaving filter material in the wall of the chamber located away from the center of the vortex clear of clogging particulate matter. The filter is described in relation to its use in a vehicle coolant circuit wherein it removes particulate matter which would otherwise tend to block heat exchangers incorporated in the circuit.
