There is a clear tube where the mercury column is that contains mercury that rises in the tube to read pressure. The rubber tube connected to the reservoir goes to the blood pressure cuff. There is a rubber bulb to fill the cuff and a valve for releasing the air.
The sphygmomanometer is a device used to measure blood pressure. The cuff restricts arterial blood flow, the bulb inflates the cuff, the valve on the bulb deflates the cuff, and the and the manometer measures air pressure. A stethoscope is also necessary to hear the Kortokoff sounds for an accurate blood pressure reading.
There is a proportioning valve and once the repair is done and you have bled all the air out of the system the valve should reset itself unless it is stuck. If it is stuck you may have to replace the valve assembly if you can't free it up.
