Latest Patents

Wilhelm holds a patent for a dry gas shutdown seal. This invention features a housing with an annularly-shaped channel that is concentric with the drive shaft. It includes an inlet for introducing pressurized buffer gas into the housing interior. The design incorporates an annularly-shaped shutdown piston that is slidably received in the housing channel for axial shifting. This piston includes a circumferential seal between its inside and outside surfaces, as well as an end seal. A biasing member is included to resiliently urge the shutdown piston toward an open position. During compressor operation, the combined forces of the biasing member and the pressure of the buffer gas retain the piston in the open position. Upon compressor shutdown, the pressure of the process gas acting on the piston’s exterior face shifts the piston to a closed position, preventing contaminants from entering the housing interior.
