FIELD: engine engineering.
SUBSTANCE: bench comprises machine to be tested, driving engine connected with the machine through a hydraulic transmission that switches in the controllable pump kinematically connected with the driving engine, tank, and hydraulic machine kinematically connected with the machine to be tested and the controllable pump through the supplying hydraulic line and tank through the discharging hydraulic line and controllable valve. The safety valve and slide valve with the overflow valve are interposed between the hydraulic lines. The hydraulic machine can be controlled. The discharging hydraulic line is connected with the supplying hydraulic line through the check valve and tank through the valve. The outlet of the overflowing valve is connected with the space of the housing of the hydraulic machine which is connected to the tank via the additional hydraulic line.
EFFECT: enhanced reliability and reduced metal consumption.
