About This Product

The Industrial Revolution in England in the 1770s began with the invention of the reciprocating steam engine. Since then, it has continued to be improved and developed as a reciprocating gasoline engine and diesel engine. However, for the last 240 years, engineers have been aware of the mechanical losses caused by the reciprocating motion of reciprocating pistons, but have not been able to find a solution. Among these, Mazda Motor Corporation was the only company to develop a rotary engine, but due to structural reasons, they were unable to perfect their manufacturing technology to the point where the cylinder was airtight enough to be commercially viable. Even now, the mainstream of automobile engines for the general public is the reciprocating type. Reducing CO2 emissions in order to reduce the environmental burden on the earth is a strong demand of the times, and the development of highly efficient rotating equipment that uses gas and liquid is desired. Our company has developed the cylinder device in the title to meet the demands of this era.

■Specific effects

The fully rotating balanced cylinder device eliminates mechanical loss due to the reciprocating movement of the piston that occurs in the reciprocating method. ・High efficiency. ・Low vibration and noise. (There is almost no vibration or noise due to the reciprocating movement of the piston) ・Structurally, it is possible to make the cylinder smaller and lighter as an inevitable effect. Also, structurally and in principle, the fully rotating balanced cylinder device has a remarkable effect in fields that require high-speed rotation.

■Application field

Target fields such as rotary compressors, scroll compressors, screw compressors, and reciprocating compressors are all applicable fields.

■Specific application fields include:

・Internal combustion engine in general ・Pneumatic compressors (air conditioners, refrigerators, etc.) ・Vacuum pump ・Fluid transfer pump for gas, liquid, etc. ・Motor using gas pressure or liquid pressure ・Application to turbo pumps and turbines The scope of application is extremely wide. It is also expected that it will be applied to the field of medical equipment, where it can take full advantage of its quietness and energy-saving properties.
