Abstract (en)
[origin: WO2018224903A1] A floating-piston motor pump comprises a body delimited by a coil, an inlet duct and an outlet duct, a sliding piston and a magnetic sleeve coaxial to the sliding axis of the piston; the magnetic sleeve interacts with the pair of magnetic bearings to increase the magnetic attraction force exerted on the piston and there are also noise-decreasing means operatively active and located between the magnetic sleeve, the piston and the body.
