Latest Patents
One of Hirofumi Katoh's latest patents involves a viscous fluid coupling. This innovative device includes a housing that is rotatably supported to a drive shaft of an engine. An operation plate set within the housing divides the space into a reservoir and an operation chamber. The operation plate features a communication hole that connects the reservoir and the operation chamber. A rotor, which is fixed to the drive shaft, is located in the operation chamber. Additionally, a valve mechanism is installed on the operation plate to open and close the communication hole based on the ambient temperature of the housing. A driven wheel, fixed to the housing, is positioned between the operation plate and the rotor. The torque transmitting section consists of a first annular projection on the driven wheel and multiple second annular projections on the rotor. These projections are designed to establish fluid coupling through the viscous fluid.
