Introduction

Takehiko Asada is a notable inventor based in Kanagawa, Japan. He has made significant contributions to the field of pressure relief valves, holding a total of 2 patents. His innovative designs have the potential to enhance safety and efficiency in various applications.

Latest Patents

Asada's latest patents include two distinct pressure relief valves. The first patent is for a "Two-way pressure relief valve for reservoir." This valve features a main body with a central chamber that defines an outer radial seat, a positive-pressure port with an inner radial seat, and a negative-pressure port that includes an internal passage spanning the outer seat. The design incorporates a sealing disk with an anchor body retained in the central chamber and a flexible diaphragm that is biased against the outer seat. This innovative mechanism allows for the controlled release of gas when pressure thresholds are exceeded.

The second patent is for a "Two-way pressure relief valve for blood reservoir." This valve consists of a housing body that forms first and second subchambers in fluid communication. It includes a first opening that forms a first valve seat and at least one second opening that forms a second valve seat along the outer perimeter. The diaphragm member is designed to deflect under negative pressure, while a sealing ball is biased against the first valve seat and responds to positive pressure. This design is crucial for maintaining the integrity of blood reservoirs.
