<p>PURPOSE:To manage with a small quantity of high pressure gas pressing out single liquid fuel and reduced the size and weight of the liquid pressure type propelling device, by providing said propelling device with single liquid fuel and a gas generator and using alternately two operating tanks. CONSTITUTION:A liquid pressure type propelling device is constituted of two operating liquid tanks 6, 7 for driving a propeller P, a gas generator 12 generating operating gas by means of resolving single liquid fuel, a single liquid fuel tank 14, a high pressure gas tank 15, the first and the second control valves 9, 8 and the like. When a valve 13 is opened, the single liquid fuel is pressed in the gas generator 12 from the tank 14 by the pressure of gas in the high pressure gas tank 15 and becomes operating gas by means of resolution. Then, the gas enters the operating liquid tank 6 through the first control valve 9 and a pipe line 11-1, and compresses the operating liquid. Then, the operating liquid in the tank 6 flows in a pipe line 5-1 by the work of the second control valve 8 and drives a motor 1 and an actuator 2 in order to have the propeller P and a rudder R driven. High pressure gas is managed with a small quantity by using the operating liquid tanks 6, 7 alternately.</p> |
