Latest Patents

One of his latest patents is for decoupler devices designed to prevent backdrive in air turbine starters. This invention includes a housing and a flow path that communicates gas flow, featuring a turbine member, a clutch, and a decoupler device. The decoupler device is ingeniously designed with a first shaft portion that rotates with the output member and a second shaft portion that rotates with the engine. These components are axially aligned to engage for rotation in one direction and to separate in another, effectively decoupling the output member from the engine. Additionally, a bearing is included to reduce friction when the two shaft portions are decoupled.

Another notable patent is the seal pressure vent system for a waterjet apparatus. This system is designed to provide a fluidic path for high-pressure water flow away from a lip seal assembly toward a near ambient pressure region. The innovative design includes multiple fluid passageways formed in a stator structure, enhancing the efficiency of the waterjet propulsion apparatus.
