Title: Sead Veletovac: Innovator in Hydraulic Elevator Technology
Introduction
Sead Veletovac is a notable inventor based in Dübendorf, Switzerland. He has made significant contributions to the field of hydraulic elevator technology, holding a total of 4 patents. His innovative designs focus on improving the efficiency and control of hydraulic elevators.
Latest Patents
One of his latest patents is a valve control unit for a hydraulic elevator. This control valve unit 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, during the downward movement, the hydraulic oil flows back to the tank without the pump operating. This system utilizes a single pilotable control valve that functions as both a check valve and a proportional valve.
Another significant patent is a control method and apparatus for a hydraulic elevator that relies solely on load pressure data. This method allows for precise control of the elevator car's movement by using a hydraulic drive mechanism. The load pressure sensor detects the pressure in the cylinder line, enabling the control apparatus to regulate the elevator's operation effectively. This innovation ensures that both upward and downward movements of the elevator cabin can be managed with high precision.
