Latest Patents

One of Kondou's latest patents is an automobile hydraulic shock absorber. This invention includes a cylinder body, a piston, an upper support, a piston rod, a volume adjustment mechanism, first and second communicating passages, and a pressure-applying mechanism. The piston rod is attached to the upper support via a rubber cushion. The volume adjustment mechanism features a free piston, while the communicating passages connect the first and second oil chambers within the cylinder body through a diaphragm. The pressure-applying mechanism is positioned outside the cylinder body, with its movement restricted by the upper support, allowing it to push the piston rod downward.

Another notable invention is a damper designed to improve damping efficiency. This damper consists of a cylinder tube with a first end connected to a member of an object for damping, and a fixing rod guide that closes the second end of the cylinder tube. A movable rod guide is fitted on the first end, and a main piston rod extends from the piston side, passing through the fixing rod guide. A sub-piston rod also extends on the piston side, passing through the movable rod guide. A spring normally biases the movable rod guide toward the piston, and a damping force generation oil passage connects the first and second oil chambers defined by the piston. This design reduces the number of parts in a through-rod type damper, simplifying its construction and making it more compact.
