Latest Patents

Sakakibara holds a patent for a "Shaft seal and turbine using the same." This invention features a shaft seal designed with high abrasion resistance, which effectively reduces gas leakage from the high-pressure side to the low-pressure side. The shaft seal consists of multi-layered flexible leaves arranged in a ring shape. It is primarily utilized around the rotation shaft of gas turbines. The design ensures that under rated operating conditions, the top ends of the leaves slightly separate from the rotation shaft due to dynamic pressure, while they make contact again when the turbine is not in operation.
