FIELD: engine devices and pumps.
SUBSTANCE: engine piston block is reciprocable along fixed tube with clearance. When the temperature of piston block in the composition of the pistons and rods is increased, control system moves the supply valve of air compressed in pistons compressor cavities to the open position. A part of compressed air flows to the turbine, which drives the coolant pump and fan. Pump pumps the coolant through the duct inside of fixed pipe and radiator, which is blown by fan. Control system monitors the temperature of coolant and, when it falls, closes the valve in compressor cavities. The coolant circulation stops.
EFFECT: reducing the loss of coolant.
