41 Liquid-Ring Vacuum Pump US14359625 2012-11-22 US20140322039A1 2014-10-30 Heiner Kösters; Matthias Tamm; Daniel Schütze
A liquid-ring vacuum pump comprises a pump casing and a shaft eccentrically mounted in the pump casing. An impeller and a rotor of a drive motor are connected to the shaft. A disk cam is arranged parallel to the impeller. A first main bearing for the shaft is arranged between the impeller and the rotor of the drive motor, on the plane of the disk cam. The impeller is arranged between the first main bearing and a second main bearing. The arrangement of the bearings prevents the shaft from bending, thus allowing the leakage gap between the impeller and the disk cam to be kept small.

43 Electro-rheological transducer US557581 1983-12-02 US4493615A 1985-01-15 James E. Stangroom
A transducer with which mechanical rotary motion can be interconverted with the flow of an electro-rheological fluid. Two, electrically conductive, movable, conveying surfaces are partly disposed in parallel confrontation thereby defining a fluid transfer path. A fluid transfer port is located at each end of the fluid transfer path through which electro-rheological fluid can enter and leave the transducer. The conveying surfaces are electrically connected to a voltage source and movable by means of a rotor to which they are connected. On application of a voltage difference between the conveying surfaces the electro-rheological fluid gells after which rotation of the rotor will urge the fluid along the transfer path and vice-versa.

45 MICROFLUIDIC PUMP US14968340 2015-12-14 US20160319806A1 2016-11-03 MAJID ASHOURI; MOHAMMAD BEHSHAD SHAFII; AYDA SHAHRIARI
A microfluidic pump comprising a cylindrical chamber, transfer ports comprising an inlet port and an outlet port positioned on the cylindrical chamber, a magnet member attached outside the cylindrical chamber, a magnetic piston in sliding communication with inner walls of the cylindrical chamber, a magnetic material, and a valve member. The magnetic material self assembles to form a seal plug separating the inlet and outlet port, where the seal plug forms a link between the magnet member and the magnetic piston to rotate the magnetic piston along the inner wall of the cylindrical chamber, where a working fluid suctioned within the cylindrical chamber is discharged at the outlet port during a movement of the magnetic piston from the inlet to outlet port. The valve member positioned at the outlet port prevents the backflow of the working fluid towards the inlet port after the magnetic piston rotates past the outlet port.
