Title: Ryuichiro Yonemoto: Innovator in Screw Compressor Technology

Introduction

Ryuichiro Yonemoto is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of screw compressor technology, holding a total of 5 patents. His innovative designs have enhanced the efficiency and functionality of screw compressors, which are widely used in various industrial applications.

Latest Patents

One of his latest patents involves a screw compressor that includes a screw rotor, an electric motor for driving the screw rotor, bearings supporting the screw rotor, and casings housing these components. This design features an oil feeding passage formed in the casing, which feeds oil on a high-pressure side to the bearings by utilizing the differential pressure between the high-pressure and low-pressure sides. Additionally, it includes an oil feeding amount adjusting unit that consists of a cylinder, a valve element that reciprocates inside the cylinder, and multiple flow paths with different areas. These flow paths are switched to adjust the oil feeding amount to the bearings based on the differential pressure.

Another patent describes a slide valve that forms part of a bore and is movable in the axial direction of the rotors. This design includes foot sections on the discharge side end face of the slide valve, along with discharge ports on the discharge chamber side. The slide valve effectively discharges compressed gas taken into a compression operation chamber from the suction chamber. It features first discharge channels that lead the compressed gas to the discharge chamber and second discharge channels that open to the first discharge channels, allowing a portion of the compressed gas to be fed back to the discharge chamber.
