FIELD: hydraulics.

SUBSTANCE: hydraulic system has main pump connected with the sucking vessel through a pipe, drain line connected to the vessel, fluid cooler, jet pump mounted inside the vessel whose housing is spring-loaded with respect to the vessel tank, slide valve of the distributor mounted in the drain line whose one end is connected with the cooler and the other end is connected with the jet pump, and fluid parameter pickup connected to the slide valve. The outlet of the jet pump is connected with the sucking pipeline of the main pump. The mixing chamber is in communication with the vessel. The fluid parameter pickup is made of a hydraulic resistance and is mounted in the drain line upstream of the slide valve. The face space of the slide valve opposite to the spring is connected with the passage which is in communication with the drain line upstream of the fluid parameter pickup. The fluid heater is interposed between the slide valve and the face space of the jet pump. The wall of the sucking pipeline is provided with two check valves made of flexible plates..

EFFECT: enhanced accuracy of temperature control and simplified design.
