Abstract: A valve assembly includes a sensing device, a main spring, a bonnet located below the sensing device, a piston with a through hole, and a valve stem connected with the sensing device and having a penetrating part through the through hole. The sensing device drives the valve stem to drive the piston. The valve assembly also includes an auxiliary spring arranged between the bonnet and the piston. The penetrating part is longer than the depth of the through hole and the valve stem is slidably coupled in piston. The valve assembly can prevent the valve stem from transferring the force of the main spring to the piston, so as to avoid damaging the valve port, the valve stem, and the piston when the force of the main spring is too large.

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.
