Title: Daisuke Watari: Innovator in Refrigeration Technology

Introduction

Daisuke Watari, an inventive mind based in Tokyo, Japan, has made significant contributions to the field of refrigeration technology. With a total of four patents, his work primarily focuses on innovations that enhance the efficiency and functionality of pressure control systems.

Latest Patents

Watari's latest inventions include a pressure control valve and an expansion valve. The pressure control valve features a valve main body with a chamber, a refrigerant inflow port, and an outflow port. It is equipped with a pressure response element that consists of a diaphragm and a lid-like member forming a sealed pressure chamber. This innovation utilizes an inert gas with a low thermal expansion coefficient, ensuring precise control of the valve mechanism. When the pressure in the valve chamber exceeds a predetermined level, the valve reaches a full-open state, optimizing the refrigerant flow.

The expansion valve, another of Watari's notable inventions, includes a body with an orifice that connects high and low-pressure passages for refrigerant flow. The valve is designed with a plug for flow rate adjustment, an operating rod for movement, and a temperature sensing drive unit to effectively control the refrigerant flow. A uniquely designed support ring constrains the spherical valve plug, allowing for better performance through elastic deformation and vibration-proof mechanisms provided by springs.
