Latest Patents
One of Atsumi's latest inventions is the self-contained type automatic belt tensioner. This device is designed to adjust the tension of an engine timing belt in automobiles. The tensioner features a body, a plunger that is slidably mounted within the body, and a reservoir chamber located in the plunger. Additionally, it includes a pressure chamber situated between the plunger and a closed wall of the body, a rod member fixed to the plunger, and a bellows-shaped elastic diaphragm. This diaphragm is fixed at one end to the rod member and at the other end to the body. The design also incorporates a check valve that allows fluid flow only from the reservoir chamber to the pressure chamber, along with a return spring that biases the plunger towards the rod member.
Another significant patent is the crank damper pulley structure for internal combustion engines in cars. This structure features a hub that is removably fixed to the tip of the engine crankshaft, transmitting power to auxiliary machinery such as an alternator. The hub contains a cavity that opens at one end, where a damper support is fixed. A ring-like damper and a ring-like damper mass are superposed axially, with the rubber fixed to both the mass and the support. This configuration creates a ring-like dynamic damper that addresses bending vibrations of the crankshaft.
