Title: José Izquierdo and a Torsion-Damped Motor Vehicle Starter

Introduction

José Izquierdo is an inventor associated with Villefontaine, France, and Valeo Equipements Electriques Moteur. His recorded patent concerns a motor vehicle starter designed with a reduction gear and torsion-damping features.

Latest Patents

The available information lists one patent for Izquierdo: “Motor Vehicle Starter with Reduction Gear Comprising Means Forming Torsional Damper.” The invention describes a starter with an electric motor that drives a coaxial starter head through an epicyclic gearbox. Its ring gear is housed partly within a cavity in the casing and includes flexible, molded pins—particularly pins made of elastomer material—positioned between the ring gear and the casing. These pins help prevent the ring gear from rotating relative to the casing while damping torsional forces between the components. The design aims to combine secure positioning with reduced transmission of vibration and torque fluctuations.

Career Highlights

Izquierdo’s listed patent reflects work on motor vehicle starting systems and gearbox design. The invention focuses on the interaction between the gearbox ring gear and starter casing, using flexible elements to provide both rotational restraint and torsional damping. The supplied information associates him with Valeo Equipements Electriques Moteur.

Collaborations

Pierre Valot and Pascal Jacquin are identified as Izquierdo’s coworkers. The available information does not specify their roles in the patent or whether they collaborated directly on this invention.

Conclusion

José Izquierdo’s recorded patent presents a motor vehicle starter design that uses flexible ring-gear supports to combine rotational immobilization with torsional damping.
