Title: Hiroshi Shiozaki: Innovator in Variable Displacement Vane Pump Technology
Introduction
Hiroshi Shiozaki is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of engineering, particularly in the development of variable displacement vane pumps. With a total of 4 patents to his name, Shiozaki's work has had a notable impact on fluid dynamics and mechanical engineering.
Latest Patents
Shiozaki's latest patents focus on innovative designs for variable displacement vane pumps. One of his patents describes a variable displacement vane pump that includes a first and a second fluid pressure chamber. In this design, the cam ring is made eccentric to the rotor by a pressure difference between the two chambers. A control valve regulates the pressure in these chambers, ensuring that the eccentric amount of the cam ring is minimized as the rotor's rotation speed increases. Additionally, a pressure applying section continuously applies pressure to the cam ring to enhance its eccentricity, while a movement restricting portion defines a minimum eccentric amount of the cam ring.
Another patent by Shiozaki also pertains to a variable displacement vane pump. This design similarly features a first and a second fluid pressure chamber, where the cam ring's eccentricity is controlled by a pressure difference. The control valve in this design manages the pressure to ensure that the discharge flow amount of the operating fluid is limited when the cam ring's eccentricity decreases.
