Title: Yasuyoshi Yamada: Innovator in Flow Control Technology

Introduction

Yasuyoshi Yamada is a notable inventor based in Nagoya, Japan. He has made significant contributions to the field of flow control technology, holding a total of 3 patents. His innovative designs focus on reducing valve leakage, which is crucial for various industrial applications.

Latest Patents

Yamada's latest patents include a flow control valve that features a seating surface formed on a valve element. This valve element is designed to contact a valve seat when closed, taking the shape of a part of a hypothetical spherical surface. The spherical center is aligned with the center of a supporting member, ensuring that the distance from the center to the seating surface remains constant. This design allows the valve element to seat at the periphery of the valve seat without any gap, even if the shaft is inclined, thereby significantly reducing valve leakage. The supporting member also supports a shaft connected to the valve element, which is movable in the axial direction. By prohibiting movement in the radial direction, the design prevents displacement of the shaft, ensuring that the valve element is securely seated on the valve seat.
