Liquid piston engine capable of exhausting air automatically

Abstract

The invention discloses a liquid piston engine capable of exhausting air automatically. The liquid piston engine comprises a cold air cylinder, a hot air cylinder, a heater, a heat regenerator, a cooler and a power output pipe. A liquid piston is arranged in the cold air cylinder, a liquid piston is arranged in the hot air cylinder, and the bottoms of the liquid pistons are communicated. The heater, the heat regenerator and the cooler are connected in sequence. The hot air cylinder is connected with the heater. The cold air cylinder is connected with the cooler. The power output pipe is connected to the hot air cylinder and extends upwards from the position below a set lowest liquid level in the hot air cylinder to the position above the set lowest liquid level. The wall of the hot air cylinder is further provided with an air distribution element. The air distribution element is arranged at the set lowest liquid level and makes the hot air cylinder be communicated with the power output pipe. The liquid piston engine can automatically exhaust the air below the set lowest liquid level so that the liquid level in the hot air cylinder can not be lower than the set lowest liquid level.

Description

technical field [0001] The present invention relates to engines, and in particular to a self-venting liquid piston engine. Background technique [0002] The heat engine is an external combustion closed cycle reciprocating piston heat engine. Because it was invented by Stirling in Scotland in 1816, it is also called Stirling engine, or external combustion engine. Since the hot air engine avoids the problem of detonation work of the traditional internal combustion engine, low noise, low pollution and low operating cost are realized. The power and efficiency of the hot air machine are not affected by altitude, which is very suitable for use in high altitude areas. [0003] The hot chamber, heater, regenerator, cooler and cold chamber of the hot air machine are connected in sequence to form a gas channel, and the heater is heated by an external heat source so that the gas in the gas channel flows between the cold chamber and the hot chamber. The reciprocating motion between th...

Problems solved by technology

[0009] However, for the liquid piston heat engines of Document 1 and Document 2, when working, due to the influence of volatilization of impurities in the liquid in the liquid piston, or the slight leakage of the heat engine itself, the volume of the liquid in the heat engine will decrease. In some cases, although the amount of reduction is very small and the speed of reduction is very slow, most of them will not affect the normal operation of the heat engine

However, with long-term accumulation, the liquid level in the hot cylinder will drop below the set minimum liquid level, which will affect the stability and power of the heat engine.
