Latest Patents
Hayami's latest patents include innovative designs for chain tensioners. One of his notable inventions is a chain tensioner that features a ratchet mechanism. This mechanism consists of annular teeth on a plunger and an expansible resilient ring. The design allows for a steep slope on the rear surfaces of the annular teeth, while the front surfaces have a gradual slope with a convex curvature. This unique design ensures that the rate of change of the slope decreases as the plunger retracts. Another significant patent is a ball-type tensioner, which comprises a spring-biased plunger with annular rack teeth. The teeth are engaged by radially movable balls that are received in inclined grooves. This design effectively blocks retraction of the plunger during engine start-up while allowing retraction under excessive force conditions.
