Latest Patents

One of Kazuhiro Irie's notable inventions is the "Rotary vane compressor with discharge fluid to front and rear shaft." This innovative design incorporates a first refrigerant gas passage, allowing refrigerant gas under pressure to reach the rearward ends of rotor vane slots through a rear bearing. This mechanism not only delivers back pressure to the rotor vane slots but also effectively lubricates the rear bearing. Additionally, a second refrigerant gas passage is introduced, allowing for the supply of refrigerant gas to the forward ends of the rotor vanes and front bearing. This configuration aims to provide uniform back pressure across the vanes while ensuring the lubrication of both the front and rear bearings.

Another significant patent by Irie is the "Rotary compressor with heating passage between the discharge chamber and bearing." This invention features a unique passage structure and valve arrangement that enables hot gaseous compressed working fluid to be directed into a chamber near a bearing. This advanced design serves to warm the bearing and its immediate surroundings, helping to mitigate the dilution of lubricant by the working fluid.
