[CN 201680030371.1] Hydraulic Machinery Title: Hydraulic Machinery Application Number: CN 201680030371.1 Applicant: Mathers Hydraulic Technology Co., Ltd. Application Date: 2016-3-24 Patent Type: Invention Application The hydraulic device can include two or more rings, Rotor with multiple blades and regulator. The two or more rings can be rotatably mounted within the hydraulic device and disposed adjacent to each other and configured to relatively rotate with respect to each other. The rotor may be arranged to rotate about an axis within two or more rings and may have a plurality of circumferentially spaced slots, each slot having at least one of the plurality of vanes located therein. The plurality of vanes can be configured to be movable between a retracted position and an extended position, wherein the plurality of vanes act on hydraulic fluid introduced adjacent the rotor. The adjuster may be configured to translate linearly to rotatably position the two or more rings relative to each other to increase or decrease the displacement of hydraulic fluid between the rotor and the two or more rings.
