[CN201880015900.X] Hydraulic machinery with stepped roller blades and fluid power system including hydraulic machinery with starting motor function Title: Hydraulic machinery with stepped roller blades and fluid power system including hydraulic machinery with starting motor function Application number: CN201880015900.X Applicant: Mathers Hydraulic Technology Co., Ltd. Application date: 2018-2-28 Patent type: Invention application discloses multiple designs for hydraulic devices, including multiple designs, the hydraulic device may include a rotor, a blade, and a ring. The rotor may be arranged to rotate about an axis. The plurality of blades may each comprise a blade step. Each vane of the plurality of vanes is movable relative to the rotor between a retracted position and an extended position in which the plurality of vanes work on hydraulic fluid introduced adjacent to the rotor. The roller may be mounted to a tip of each of the plurality of blades. The ring may be disposed at least partially around the rotor. The rotor may include one or more channels for hydraulic fluid to enter or exit a region adjacent to and defined at least by the rotor and the blade steps.
