Scroll compressor

본 발명은 스크롤 압축기에 관한 것이다. 본 발명은, 랩두께가 일정한 균일구간과 랩두께가 랩의 궤적을 따라 가변되는 가변구간을 가지고 상기 가변구간이 복수 개의 균일구간 사이에 형성된다. 그리고 상기 균일구간과 가변구간이 연결되는 구간은 포락선으로 형성된다. 이에 따라 토출측 랩두께를 형성할 때 흡입측 랩두께에 구애받지 않고 설계할 수 있어 토출측 랩두께를 흡입측 랩두께에 비해 현저하게 두껍게 형성할 수 있다. 이를 통해 고압축비 스크롤 압축기에서 토출측 랩이 파손되거나 압축비 대비 충분한 실링면적을 확보하지 못하여 축방향 누설이 발생되는 것을 미연에 방지할 수 있어 압축기의 신뢰성을 높일 수 있다. 그리고 이를 통해 차량과 같은 냉,난방용 공기조화기에 폭넓게 적용될 수 있다. The present invention relates to a scroll compressor. According to the present invention, a uniform section having a constant lap thickness and a variable section having a lap thickness varying along a trajectory of the lap have a variable section formed between the plurality of uniform sections. The section where the uniform section and the variable section are connected is formed by an envelope. Accordingly, when forming the discharge side wrap thickness, it can be designed irrespective of the suction side wrap thickness, and the discharge side wrap thickness can be formed remarkably thick compared with the suction side wrap thickness. As a result, the discharge wrap in the high compression ratio scroll compressor may be damaged or the sealing portion may not be secured in sufficient proportion as the compression ratio, thereby preventing axial leakage, thereby increasing the reliability of the compressor. And it can be widely applied to air conditioning and heating air conditioners, such as a vehicle.

Tapering spiral gas turbine with homopolar dc generator for combined cooling, heating, power, pressure, work, and water

A tapering exponential spiral for a gas expander (503) for work extraction or air cooling is used. This tapering exponential spiral could also be used for a gas compressor (501) to increase the pressure and temperature of air. The compressor-expander forms a single and simple structure for easy manufacturing. A simple formula for temperature drop across a tapering exponential spiral for adiabatic expansion of air is derived. The pressure increasing as air is compressed outside in for isothermal compression of air is also derived. The spiral is proved efficient for energy conversion. The Faraday homopolar DC generator by changing its geometry and technology is improved. High work to electricity conversion efficiency and high voltage and power production are achieved. The same generator structure can be used as a homopolar DC motor. By controlling voltage, the speed of the motor or generator is controlled. By controlling current, the torque force used or produced is controlled. The homopolar generator and motor can be easily integrated with the spiral compressor and expander. Three applications using these basic inventions are proposed. First a heat turbine powered by concentrated solar energy or by burning gaseous fuel is proposed. Second, a heat pump powered by electricity for cooling, refrigeration, and heating of water is proposed. Third, a method to desalinate water by solar power, using concentrated sunlight to evaporate salty water under reduced pressure is proposed. The Firefly technology can provide small scale, local, and simple production of energy of many kinds, giving solar power back to the people where and when needed.

Rotary vane internal combustion engine

Rotary vane internal combustion engine comprises of two side-by-side rotors, placed in a cylindrical housing, wherein each rotor has at least two radial vanes rigidly attached to the rotor that form chambers for intake, compression, combustion, and exhaust. Each rotor alternately engages with a shaft by overrunning one-way clutches and is held from turning back, through the damper, mounted on a corresponding flywheel and forming a part of the flywheel assembly, which is rigidly attached on the shaft. The assembled rotors from the outside are rigidly closed by flanges on each of which is mounted at least one blade. The blades are positioned into formed cavities between the rotors and caps of the housing, thereby forming two cooling cavities through which coolant circulates around rotors through openings in the housing and through longitudinal grooves in the shaft. On the vanes are mounted cylindrical and conical seals, which remove the need for lubrication.
