Abstract

Pompa ma cylindryczny korpus (1) z zespołem uzwojeń umieszczonych na nabiegunnikach wydatnych (16), wirnik (9) z magnesami trwałymi oraz ruchomy tłok (6) z magnesami tłoka (6) i zastawką tłoczną (7), usytuowany osiowo w korpusie (1). Wirnik (9) jest ułożyskowany wewnątrz korpusu (1) pomiędzy dwiema koncentrycznymi osłonami (2, 12), zewnętrzną i wewnętrzną, z których każda ma wyżłobienia, w których przemieszczają się elementy toczne (4) zawieszenia mechanicznego wirnika (9), które to wyżłobienia, wprawiające obracający się wirnik (9) w ruch posuwisto-zwrotny, mają kształt torów śrubowych połączonych w skrajnych położeniach odcinkiem nawrotnym. Wirnik (9) zawiera dwa rodzaje magnesów trwałych, lewitacyjne (5) spolaryzowane wzdłuż osi ruchu tłoka (6) oraz napędowe (3) spolaryzowane prostopadle do osi ruchu tłoka (6), a tłok (6) jest umieszczony swobodnie wewnątrz osłony wewnętrznej (12) w części kanału przepływowego (11), znajdującej się pomiędzy magnesami lewitacyjnymi (5) wirnika (9).The pump has a cylindrical body (1) with a set of windings located on prominent poles (16), a rotor (9) with permanent magnets and a movable piston (6) with piston magnets (6) and a discharge valve (7), located axially in the body (1) ). The rotor (9) is mounted inside the body (1) between two concentric shells (2, 12), external and internal, each with grooves, in which rolling elements (4) of the mechanical suspension of the rotor (9) move, which are grooves , making the rotating rotor (9) reciprocate, have the shape of helical paths connected in the extreme positions by a reversing section. The rotor (9) contains two types of permanent magnets, levitation (5) polarized along the piston movement axis (6) and drive (3) polarized perpendicular to the piston movement axis (6), and the piston (6) placed freely inside the inner shell (12) ) in the part of the flow channel (11) located between the levitation magnets (5) of the rotor (9).
