Title: Hidetoshi Arahata: Innovator in Vane Compressor Technology
Introduction
Hidetoshi Arahata is a notable inventor based in Higashimatsuyama, Japan. He has made significant contributions to the field of compressor technology, holding a total of 2 patents. His work focuses on enhancing the efficiency and reliability of vane compressors.
Latest Patents
Arahata's latest patents include a revolutionary vane compressor design. This invention aims to prevent leakage of refrigerant gas by reducing the number of airtight interfaces between component parts. It also addresses the issue of seizure between the rotor and the side block without requiring surface treatment of the side block. The design features a cam ring, with the rotor rotatably received within it. A first head is secured to one end face of the cam ring, while a second head closes the opening of the opposite end face, allowing for effective contact between the rotor and the second head. Additionally, the side block is positioned within the first head, ensuring a secure closure of the cam ring's opening.
Another significant patent is the variable capacity vane compressor. In this design, an annular piston interacts with a rotation plate, which is positioned away from a hollow cylinder via a thrust bearing. Delivery pressure is introduced to the annular piston, acting through the thrust bearing to urge the rotation plate toward the cylinder. This innovative mechanism reduces the gap between the rotation plate and the cylinder, minimizing friction resistance and facilitating smooth rotation.
