Latest Patents

Yokota is credited with 1 patent. His patent, “Flow Rate Control Valve,” describes a valve with a housing and a reciprocating spool that regulates oil flow. The housing includes a bolt for fastening a movable member of a variable valve timing mechanism, along with a sleeve fitted into the bolt. A port in the bolt and a through hole in the sleeve connect the oil passages to the sleeve’s accommodation chamber. An annular protrusion and recess help align the sleeve’s rotation so the port and through hole coincide, and maintain that alignment.
