Latest Patents

Grillo's latest patents include the "Expansion Sealing Device" and the "Pressure Relief Valve." The Expansion Sealing Device is designed to provide a sealed intersection between flow passages within a housing. It features an expansion sleeve with a cylindrical outer surface and an axially tapered inner surface that accommodates a frusto-conical inner member. This design allows for radial expansion after insertion, ensuring no interference occurs until the sleeve is securely in place. The device offers two embodiments, one sealing between axially separated ports and the other between angularly separated ports. The Pressure Relief Valve comprises a poppet member that engages a slidable tubular valve seat. This valve seat allows for unrestrained axial rotation and features a central relief flow passage. When the system pressure exceeds a threshold, both the valve seat and poppet are axially displaced, ensuring efficient operation and low leakage rates.
