Abstract
A compressed air pressure supply system includes an air compressor device, an air dryer device having a recoverable desiccant for removing moisture contained in the compressed air delivered from the air compressor device, an air reservoir for storing the dried compressed air from the dryer device, a regenerating valve which is mounted on the air compressor device on the side of the dryer device and opens the air compressor device to the atmosphere under the control of external commands, a governor device which causes a command to be transmitted to the regenerating valve when air pressure prevailing inside the air reservoir has attained a maximum value and which cancels this command when the air pressure in the reservoir has reached a minimum value, an oil separator mounted between the air compressor device and the dryer device for removing residue contained in the compressed air delivered from the air compressor device, a non-return valve for preventing the flow of fluid from the dryer device toward the drain device, and a drain valve mounted on the air compressor device on the side of the draining device and connecting the interior of the draining device to the atmosphere under the control of commands from the governor device.
