Latest Patents

Hignett's latest patents include innovative designs for mechanical seals. One patent describes a mechanical seal containing a sealing face with grooved regions. This design features a first sealing ring mounted non-rotatably and sealed with respect to a shaft, along with a second sealing ring that is also mounted non-rotatably and sealed with respect to a housing. The second sealing ring is aligned axially and is resiliently urged into sealing engagement with the first sealing ring. The sealing face of the first sealing ring has two sets of grooved areas, which are spaced angularly around its circumference. Each grooved area defines a trailing edge that is inclined at an obtuse angle to the direction of rotation. The axial depth of the grooved areas varies between the two sets, enhancing the seal's effectiveness.

Another patent focuses on a mechanical face seal that includes a first sealing ring and a second sealing ring, both mounted non-rotatably. Springs are provided to urge the sealing faces of both rings into engagement. The first sealing ring's face is equipped with multiple grooved areas that open to one edge of the sealing face. A continuous annular dam formation is situated between the grooved areas and the opposite edge. Each grooved area has multiple trailing edges defined by walls inclined at an obtuse angle to the direction of rotation, ensuring optimal sealing performance.
