Title: Inventor Yoshiharu Miya: Innovations in Hydraulic Equipment

Introduction

Yoshiharu Miya is a prominent inventor based in Sagamihara, Japan, known for his contributions to the field of hydraulic equipment. With a total of five patents to his name, Miya has made significant strides in innovations that enhance the functionality and efficiency of hydraulic systems.

Latest Patents

Among his notable inventions, Miya has developed a **solenoid actuator**, designed to be attached to hydraulic equipment. This actuator comprises a shaft connected to the hydraulic apparatus, featuring a plunger fixed to the shaft and a coil that magnetically drives the plunger. The innovative design includes two bearings that support the shaft on either side of the plunger, creating a plunger front and rear chamber. A crucial feature is the plunger exterior oil passage, which allows working oil to flow through, thereby preventing contaminants from accumulating on the plunger without increasing stroke resistance.

Another of his latest contributions is the **electromagnetic proportional flow rate control valve**. This valve is engineered to provide precise flow rate control, particularly in the low flow rate region. Miya's design enables the valve member to be driven in a closing direction as the driving current of the solenoid coil increases. The innovative setup ensures that the solenoid driving force decreases with the displacement of the valve member, improving the flow rate control precision significantly in low flow rate scenarios.
