FIELD: mechanical engineering.
SUBSTANCE: invention relates to vehicle engineering, namely to cooling systems of vehicles. Liquid cooling circuit of hydro-transformer is connected to transmission lubrication system through heat exchanger on the line between auxiliary cavity of differential relief valve and drain channel. The channel, which connects drain valve with the heat-exchanger and hydro-transformer cooler, is provided with on/off control valve where moving spring-actuated valve slide is installed. In order to control valve slide position, on/off control valve is hydraulically connected with pressure mainline of lubricating system circuit.
EFFECT: invention allows for increasing effectiveness of cooling system in hudro mechanical transmission.
