In November 2024, the company applied for a patent entitled "A servo valve hydraulic amplifier structure", with publication number CN 119308902 A

The present invention relates to the field of electro-hydraulic servo valve technology and to a servo valve hydraulic amplifier structure, comprising an armature assembly and a first stage seat. A through hole is provided in the middle of the first stage seat, and the armature assembly I is installed on the upper surface of the first stage seat through a spring tube. The lower end of the spring tube is provided with a cylindrical protrusion and the cylindrical protrusion is located in the circular through hole in the middle of the first stage seat. A disc shaped spring is placed below the cylindrical protrusion of the spring tube, and the small end of the disc shaped spring contacts the end face of the cylindrical protrusion of the spring tube. The upper pressing block is placed below the disc shaped spring, and the jet plate is placed below the upper pressing block. The lower pressing block is placed below the jet plate, and the upper pressing block, jet plate, and lower pressing block are connected and positioned by positioning pins. The armature assembly is sequentially positioned. Passing through the spring tube and the upper pressure block, jet blade, and lower pressure block arranged from top to bottom in the through hole, The sealing ring is set between the cylindrical protrusion at the lower end of the spring tube and the circular through-hole in the middle of the first stage seat. This invention can improve the environmental and service performance of the jet amplifier.
