Inventor(s) include Kazutoshi Satori; and Bakiyaraj G.
The application for the patent was published on June 20, under issue no. 25/2025.
According to the abstract released by the Intellectual Property India: "A Hydro top mount (10) comprises an inner tube (1), an outer tube (4), a bush (2), and at least two orifices (5). The outer tube (4) encloses the inner tube (1) and the bush (2) comprises an upper rubber foot (L1) that is enclosed within the outer tube (4) and a lower rubber foot (L2) that is attached around the inner tube (1). The upper rubber foot (L1) and the lower rubber feet (L2) are of different lengths (L1) and (L2) respectively to maintain flow of a fluid. The two orifices (5) are formed by the upper rubber foot (L1) and the lower rubber foot (L2), wherein the orifices (5) comprise different volumes of the fluid so that dynamic stiffness is lower at two different corresponding frequencies to reduce road noise."
