Latest Patents

Takeshita's latest patents include a shaft seal and a turbine utilizing this innovative design. The shaft seal features high abrasion resistance, effectively reducing gas leakage from high-pressure to low-pressure areas. This design incorporates multi-layered flexible leaves arranged in a ring shape, primarily positioned around the rotation shaft of a gas turbine. The turbine itself consists of a casing, a compressor, a rotation shaft, moving blades, and stationary blades, with the shaft seals strategically placed between the stationary blades and the rotation shaft. Under operational conditions, the leaves of the seal slightly separate from the rotation shaft due to dynamic pressure, ensuring optimal performance.

Another significant patent is a vibration suppressing sealing device for rotary machines. This device includes an annular groove in the stationary member's inner circumferential surface, which seals gap spaces between the rotary body and the stationary member using seal rings. A vibration suppressing movable ring is integrated within the annular groove, allowing for radial movement and creating gap clearances that enhance sealing efficiency. The design divides the inside gap clearance into multiple wedge-shaped sections, improving the overall functionality of the rotary machine.
