A pneumatic flow controlling device for a pneumatic vacuum elevator and a method thereof

A pneumatic vacuum elevator with a pneumatic flow controlling device comprising:

• an external cylinder assembly comprising an elevator cabin configured to accommodate one or more passengers;
• a motor unit mechanically coupled to the external cylinder assembly, wherein the motor unit comprises the pneumatic flow controlling device comprising:
• a perforated component disposed on a bottom component placed on a top surface of an elevator cylinder, wherein the perforated component comprises a plurality of perforations to enable air circulation from outside to inside of the elevator cylinder;
• a diaphragm component mechanically coupled to the perforated component 110 and the bottom component, wherein the diaphragm component is configured to expand and compress based on the air circulation;
• a primary valve mechanically coupled to the diaphragm component, wherein the primary valve is configured to allow an air supply to the elevator cylinder for controlling movement of an elevator cabin within a tubular pathway based on a control signal received from an elevator controller;
• and
• a secondary valve mechanically coupled to an outer surface of the bottom component, wherein the secondary valve is configured to allow the air supply to the elevator cylinder for dynamically varying speed of the elevator cabin at one or more landing positions.

A method for providing a pneumatic flow controlling device to a pneumatic vacuum elevator comprising:

• disposing a perforated component on a bottom component coupled to a top surface of a pneumatic vacuum elevator, wherein the perforated component comprises a plurality of perforations for enabling air circulation from outside to inside of the elevator cylinder;
• coupling a diaphragm component with the perforated component and the bottom component for expanding and compressing based on the air circulation;
• coupling a primary valve to the diaphragm component for allowing an air supply to the elevator cylinder for controlling movement of an elevator cabin within a tubular pathway based on a control signal received from an elevator controller;
• and
• coupling a secondary valve to an outer surface of the bottom component for allowing the air supply to the elevator cylinder for dynamically varying speed of the elevator cabin at one or more landing positions.
