Abstract (en)
A free piston type fluid pump comprising a first piston and a second piston interconnected with a torsion body and elastic bending elements, said first piston and said second piston being driven by a first motor and a second motor by applying force in opposite circumferential directions, so that in use the first piston and second piston displace along a displacement direction, wherein the said motors drive the first piston and the second piston in said opposite circumferential directions transversal to the displacement direction, wherein at least one of the first motor and second motor includes an adjustable stator.
