Title: The Innovative Mind of Eric Johnson

Introduction

Eric Johnson is a notable inventor based in Gresham, OR (US). He has made significant contributions to the field of hydraulic braking systems, holding a total of 2 patents. His work reflects a commitment to enhancing vehicle safety and performance through innovative engineering solutions.

Latest Patents

One of Eric's latest patents is the Fail-safe wheel service brake system. This hydraulic wheel braking system for vehicles features wet disc wheel brakes that are applied by a single spring-activated piston within each brake housing. Each piston can be selectively and variably disengaged from the brake discs by variable hydraulic pressure acting against the piston in opposition to spring pressure, allowing for controlled wheel rotation. During vehicle operation, brake fluid pressure at the pistons is managed by a foot pedal-operated brake valve. Additionally, a manually-operated parking and control valve assembly can selectively disable the brake valve and relieve hydraulic pressure at the pistons to spring-apply the pistons to the discs. This assembly also acts to automatically spring-apply the pistons to the discs upon a loss of brake or transmission clutch fluid pressure.
