Title: Innovations of Pascal Leguay

Introduction

Pascal Leguay is a notable inventor based in Alleins, France. He has made significant contributions to the field of hydraulic systems, holding a total of four patents. His work primarily focuses on enhancing the efficiency and functionality of hydraulic circuits.

Latest Patents

One of his latest patents is a "Duplicated hydraulic circuit with pressure regulation." This invention relates to a device for supplying hydraulic power, comprising two hydraulic circuits that jointly feed multi-cylinder hydraulic power transmission means. Each cylinder is connected to a single hydraulic circuit independently of the others. The hydraulic circuits include a pressure and flow rate generator, along with a pressure control module that regulates the pressure of the fluid flowing in each circuit based on various parameters.

Another significant patent is the "Double hydraulic valve of a servo-control for feathering the blades of a rotorcraft rotor." This hydraulic valve features a main valve member and an emergency valve member, which is blocked relative to a valve cylinder by a pin in sliding thrust engagement. The design allows for relative movement between the emergency valve member and the valve cylinder, initiating the sliding movement of the pin and enabling the emergency valve member to move freely when required.
