Title: Innovations of Fujiya Maruno
Introduction
Fujiya Maruno is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of mechanical engineering, particularly in the development of variable-stroke mechanisms. With a total of 4 patents, Maruno's work showcases his innovative approach to solving complex engineering challenges.
Latest Patents
One of Maruno's latest patents is the "Variable-stroke crank mechanism." This invention features a crankshaft that is rotatably supported in a casing, allowing for relative rotation about an axis. The crankpin is displaced out of alignment with the axis, and an eccentric collar is mounted on the crankpin. This design enables the actuator to be reciprocally moved relative to the casing. The stroke adjusting mechanism allows for the adjustment of angular displacement of the eccentric collar, which in turn adjusts the stroke of the actuator's movement.
Another significant patent is the "Radial-pluger-type apparatus with variable plunger stroke." This apparatus is designed for use as an air compressor and includes a main shaft rotatably disposed in a casing assembly. The eccentric collar is angularly movably mounted on an eccentric crankpin of the main shaft. The design incorporates a coupling ring and a plurality of radial plungers that are slidably fitted in respective cylinders. The angular movement of the eccentric collar is adjustable, enhancing the functionality of the apparatus.
