Abstract: A drive device and a valve including the drive device. The drive device senses the pressure of a working medium and generates a drive force to control the flow of the working medium. The drive device includes a sensing part with a chamber and a drive shaft. Vents and an air exhausting device are arranged on the chamber. The drive device and the valve including such a drive device can exhaust air entering the chamber along with the working medium out of the chamber by the vents on the chamber thereby optimizing the performance of the drive device and the valve and helping to keep the valve operating in a stable manner.
