[0007] BACKGROUND

[0008] The development of elevators was led by the need for the movement of heavy materials and lifting goods. The elevators provide easy transportation and are timesaving technology. Also, the elevators provide space-saving designs, enhanced security and are useful in emergency situations. Several types of elevators are available such as pneumatic elevator systems, vacuum elevator systems, and the like.

[0009] The pneumatic vacuum elevators use air pressure to cause the motion of the cabin within a tubular cylinder. The air is used as a working fluid upon the confines of the cabin. Typically, many valves have been designed for controlling the flow of air to and from chambers in order to move an elevator cabin down in the tubular pathway. However, such conventional valves absorb tremendous amount of power in their operation. Also, the conventional air valves for activation during safely measurement are unable to allow the flow of air through the orifice in order to achieve a cabin’s descending speed. Further, the current system uses the air controls utilised to move the pneumatic type of elevator which require large amount of power. More specifically, the existing pneumatic valve does not have effective control of the flow of air to and from chambers in-order to move an elevator cabin (CAR) assembly down its circular flattened pathway.

[0010] Hence, there is a need for an airflow controller in a pneumatic vacuum elevator and a method to operate the same to address the aforementioned issue(s).

[0014] Further, an objective of the present invention is to provide the airflow controller which requires less power consumption.
