Title: Innovations of Maria S. Vlamakis
Introduction
Maria S. Vlamakis is a notable inventor based in Justice, Illinois. She has made significant contributions to the field of continuously variable transmissions, holding 2 patents that showcase her innovative spirit and technical expertise.
Latest Patents
Her latest patents include a "CVT hydraulic start clutch" and a "starting clutch for a continuously variable transmission." The CVT hydraulic start clutch is designed to reduce the centrifugal torque of the clutch in relation to the chain belt/sheave torque. This is achieved by adjusting the diameters of the clutch piston, which lowers the resultant clutch torque. The design features oil feed passages that ensure oil is fed through openings in the friction plate during operation, even when the friction plate is not rotating. Additionally, an improved retractor spring is utilized, which includes circumferentially extending tabs to prevent the release of the snap ring due to centrifugal force during clutch operation. The starting clutch for a continuously variable transmission incorporates a rotating shaft and a pressure chamber that houses a piston, pressure plate, and end plate. It also includes at least one clutch plate and a diaphragm spring, with a separator formed of parallel plates to equalize loading on the clutch plates.
