GAS-LIQUID MACHINE Russian patent published in 1997 - IPC

FIELD: engine engineering. SUBSTANCE: machine has two tanks partially filled with liquid. To the first tank a hydraulic motor is connected. The outlet of the hydraulic motor is connected to the second tank. The pressure of liquid in the first tank is higher than that in the second tank. As a result a pressure drop is at the working member of the hydraulic motor that allows generation of mechanical energy. There is also a slide valve with a chamber. The slide valve reciprocates. The chamber of the slide valve is connected alternatively with the first and the second tanks. When the slide moves from the first tank to the second tank the chamber brings gas whereas moving back the chamber brings liquid. EFFECT: improved efficiency. 4 cl, 5 dwg
