Latest Patents

Hiroshi Yokoyama holds a patent for an injection device and molding machine. This invention features a run-around circuit that allows hydraulic fluid to be discharged from a rod-side chamber as a piston moves forward in an injection cylinder. The design includes a servo valve connected to a tank, which regulates the flow of hydraulic fluid between the rod-side and head-side chambers. In the first state, the servo valve permits flow from the rod-side chamber to the head-side chamber while prohibiting flow to the tank. Conversely, in the second state, the valve allows flow to the tank while blocking flow to the head-side chamber. This innovative control mechanism enables precise management of hydraulic fluid flow rates.
