Abstract

Un sistema di raffreddamento per motori endotermici presenta un circuito del liquido refrigerante, portato sui suoi cilindri di combustione, con una pompa di mandata (12), un radiatore (11) ed uno scambiatore di calore (13, 14) per un dispositivo di riscaldamento e una valvola a 3/2 vie (16, 17) per sbarrare e liberare alternativamente il flusso del liquido refrigerante attraverso lo scambiatore di calore (13, 14) e attraverso un condotto di aggiramento (23) verso lo scambiatore di calore (13, 14). Per assicurare una sufficiente portata di liquido refrigerante attraverso lo scambiatore di calore (13, 14), in caso di bassi numeri di giri del motore endotermico, e per il post-raffreddamento del motore endotermico dopo che esso è stato arrestato, nel circuito del liquido refrigerante è inserita un'aggiuntiva pompa (18) del liquido refrigerante, che è azionata elettricamente ed è riunita preferibilmente con una valvola a 3/2 vie (16, 17) per formare una unità costruttiva (15) (Figura 1).A cooling system for internal combustion engines has a coolant circuit, carried on its combustion cylinders, with a delivery pump (12), a radiator (11) and a heat exchanger (13, 14) for a heating device and a 3/2 way valve (16, 17) to alternatively block and release the flow of the coolant liquid through the heat exchanger (13, 14) and through a bypass duct (23) towards the heat exchanger (13, 14). To ensure a sufficient flow of coolant through the heat exchanger (13, 14), in case of low rpm of the internal combustion engine, and for post-cooling of the internal combustion engine after it has been stopped, in the liquid circuit refrigerant an additional coolant pump (18) is inserted, which is electrically operated and is preferably assembled with a 3/2 way valve (16, 17) to form a construction unit (15) (Figure 1).
