Title: Innovations by Hirotaka Kameya: Pioneering Compressor Technologies
Introduction
Hirotaka Kameya, a prominent inventor based in Tsuchiura, Japan, has made significant contributions to the field of compressor technology. With a remarkable portfolio of 20 patents, Kameya's innovations focus on enhancing operational efficiency and reliability in industrial compressors.
Latest Patents
Among his latest patents are two groundbreaking inventions: the oil-cooled screw compressor and the water-injected scroll air compressor. The oil-cooled screw compressor features a unique design where a tooth crest arc of a fixed width is incorporated into the tooth crest of a male tooth profile. This design allows the operation chamber to exist primarily in the bottom half region, significantly increasing the opening area compared to the chamber volume. Consequently, the smooth discharge of oil is achieved, thus minimizing energy loss during operation.
The water-injected scroll air compressor represents another leap in compression technology. It includes an orbiting scroll and a fixed scroll, coupled with a motor that drives the orbiting motion. A key innovation of this design is its ability to switch between water-injection and non-water injection modes. This switching mechanism effectively prevents issues such as corrosion and activation failure, ensuring efficient operation without residual water in the air end.
