Title: Innovations of Jean-Pierre Delage
Introduction
Jean-Pierre Delage is a notable inventor based in Saint Mande, France. He has made significant contributions to the field of electro-hydraulic braking systems, holding a total of five patents. His work has advanced the technology used in vehicle braking systems, enhancing safety and efficiency.
Latest Patents
One of Delage's latest patents is an electro-hydraulic brake circuit for a vehicle. This invention addresses the issue of malfunctioning elements within the brake circuit. When a component fails, the master cylinder can still brake the vehicle. The design includes a brake actuation simulator that disconnects from the master cylinder using an O-ring gasket. This gasket is compressed between a groove in a secondary piston and a bore in the master cylinder. To prevent the gasket from being extruded during brake release, a pressure relief duct is incorporated inside the secondary piston. This allows extra pressure to be discharged during brake release through the brake release duct, ensuring the system functions effectively.
Another significant patent is for a compact tank designed for an electro-hydraulic braking system. This tank features multiple chambers, including one for supplying the primary hydraulic circuit of the master cylinder with brake fluid. It also includes a chamber for the secondary hydraulic circuit and a chamber for the hydraulic pump. Additionally, a measuring chamber accommodates a detection device that indicates when the brake fluid level is too low. The tank is designed to interconnect the chambers when the hydraulic fluid level is above a safety threshold, ensuring proper functionality.
