Title: Luigi Del Re: Innovator in Hydraulic Elevator Technology
Introduction
Luigi Del Re is a notable inventor based in Zurich, Switzerland. He has made significant contributions to the field of hydraulic elevator technology, holding 2 patents that showcase his innovative approach to engineering solutions.
Latest Patents
One of his latest patents is a "Valve control unit for a hydraulic elevator." This invention includes two control valves that manage the flow of hydraulic oil from a tank to a lifting cylinder, which drives the elevator cabin. During the upward movement of the elevator cabin, hydraulic oil is pumped from the tank through the control valve unit to the lifting cylinder. Conversely, when the elevator cabin descends, the hydraulic oil flows back to the tank without the pump operating. This system utilizes a single pilotable control valve that functions both as a check valve and a proportional valve.
Another significant patent is the "Control method and apparatus for a hydraulic elevator using only load pressure data." This method allows for precise control of a hydraulic elevator's movement by utilizing a load pressure sensor to detect pressure in the cylinder line. The elevator's operation is regulated by adjusting the control of the second control valve unit, ensuring accurate movement whether the elevator car is ascending or descending.
