Abstract: A fluid working machine comprises a rotor (7) with a blading (10) comprising 40 to 65 blades that radially project out of a body central and are suitably circumferentially offset on a plane normal to the axis of symmetry of the rotor, according to an appropriate spacing rule that can eliminate or appreciably attenuate the acoustic emission components that are mostly annoying to the human ear or at frequencies close to the resonance frequencies of other parts of the working machine.

Abstract: A rotor for a pump, such as a blood pump, may include a hub configured to rotate around a central axis, and at least one rotor blade coupled to and extending away from an outer surface of the hub, the rotor blade comprising a medical-grade polyurethane, the rotor blade configured to have a crimped state and a running state. The medical-grade polyurethane may be configured for casting or injection molding, and upon curing, the medical-grade material advantageously has a shore A hardness of 90-100, or a shore B hardness of 35-55, and a Young's modulus of 60 MPa-250 MPa. When crimped, the rotor blades are compressed and exposed to strains of up to about 160% in a dry environment at temperatures of 20-25° C. When running, the rotor blades are expanded and exposed to strains of up to 10% in a wet environment at temperatures of 36-38° C.

Abstract: A hydraulic pump includes a casing, and an impeller pump having a rotor that is rotationally mobile with respect to the casing about a first axis. The rotor includes several blades in helix form, a transition zone belonging to the casing and having, on the side of the impeller pump, a ramp in helix form developing in the same direction as the helix form of the blades. A trochoid pump includes a rotor with outer toothing secured to the rotor of the impeller pump. A rotor with internal toothing is rotationally mobile with respect to the casing about a second axis parallel to and offset from the first axis. The trochoid pump is fed by the impeller pump through the transition zone running along the ramp.

Abstract: The invention relates to a fluid pump, in particular to a liquid pump having a rotor with at last one rotor blade for conveying the fluid, the rotor being variable with respect to its diameter between a first, compressed state and a second expanded state. In order to produce a simple compressibility and expandability of the rotor of the pump, it is provided according to the invention that at least one rotor blade is deformable between a first state which it assumes in the compressed state of the rotor and a second state which it assumes in the expanded state of the rotor by means of a fluid counterpressure during a rotation of the rotor during pump operation.
