COOLING SYSTEM FOR LIQUID COOLING OF A COMBUSTION ENGINE

摘要

The invention relates to a cooling system for liquid cooling of a combustion engine. The system comprises an engine block (2) with cooling ducts, a radiator (3) and a coolant pump (1) of centrifugal type. A line circuit connects these components to one another to form a closed circuit for circulation of coolant. According to the invention, the coolant pump (1) is provided with a secondary outlet aperture (9) adapted to separating a partial flow from the coolant. A return line (10) connects the secondary outlet aperture (9) to the line circuit at a point (6) situated after the engine block (2) but before the coolant pump (1) in the coolant flow direction. A particle filter (5) is provided in the return line (10).
