COOLING SYSTEM FOR HYDRAULIC TRANSFORMER FLUID Russian patent published in 2006 - IPC F16H41/30 B60K17/10 

FIELD: transport mechanical engineering.

SUBSTANCE: cooling system comprises tank for fluid, supplying hydraulic pump for the cooling system, cooler for fluid mounted at the drain of the fluid from the hydraulic transformer, drain valve interposed between the hydraulic transformer and cooler, and differential reduction valve which has main working space connected with the pressure line of the hydraulic pump and auxiliary working space connected with the inlet of the cooler. The fluid cooling circuit of the hydraulic transformer between the auxiliary space of the differential reduction valve and drain valve is connected with the cooling circuit of the internal combustion engine through the heat exchanger. The passage that connects the drain valve with the cooler of the hydraulic transformer is provided with the two-positioned distributor.

EFFECT: expanded functional capabilities.
