Introduction

Cheryl Chunyu Dou is a notable inventor based in Farmington, CT (US). She has made significant contributions to the field of valve technology, particularly with her innovative designs that enhance functionality and efficiency.

Latest Patents

Cheryl holds a patent for a "Check valve flapper with reduced moment of inertia and method of making." This invention features a check valve that includes a valve seat defining an aperture and a seating surface. The flapper, which is a single homogeneous component, is pivotally movable relative to the valve seat. In the closed position, the contact surface of the flapper sealably engages the seating surface, occluding flow through the aperture. In the open position, the contact surface is distanced from the seating surface. The design incorporates a filler portion with a plurality of voids, resulting in a lower density for the flapper compared to a solid component. This innovative approach not only improves performance but also simplifies the manufacturing process.
