Title: Innovations of Katsuyoshi Wada
Introduction
Katsuyoshi Wada is a prominent inventor based in Shizuoka, Japan. He has made significant contributions to the field of compressor technology, holding a total of 8 patents. His work focuses on enhancing the efficiency and reliability of scroll-type compressors.
Latest Patents
Wada's latest patents include innovative designs for scroll-type compressors. One notable invention is a scroll type compressor featuring a drain oil tube with a flexible section. This design incorporates a compression unit, a crankshaft with an oil passage, and an electric motor stator with an oil return hole. The oil pump feeds oil into the crankshaft's oil passage, while the drain oil tube effectively channels return oil from the compression unit to the motor stator's oil return hole. The upper non-flexible drain opening receives oil, which then travels through a non-flexible portion with a bend before reaching the flexible section that extends into the motor stator.
Another significant patent is a scroll compressor equipped with a gear oil pump that accommodates reverse rotation. This invention ensures that even if the compressor is mistakenly rotated in reverse, it prevents the establishment of a vacuum state within the compression chamber, thereby avoiding damage to the stationary and orbiting scrolls. The gear pump's design allows the pump case to rotate 180 degrees during reverse rotation, ensuring that lubricating oil is supplied to all sliding components of the compressor.
