The details necessary for embodying the present invention are: a supporting frame; two rotors; a system for the periodic alternating motion thereof with phases of 0° and 90°; two tubular 2-phase circuits (CB) consisting of two parallel identical tubes termed “active circuits” with an inlet and outlet tube at the connection points; starting from the inlet, where to each circuit is applied a one-way valve with the task of allowing only inlet of the liquid, the two circuits constituting the CB are wound one with right-hand direction and the other with left-hand direction; on each rotor an identical CB is fastened. The inlet of the first CB is connected with the feed source and the outlet with the inlet of the other CB, whose outlet is connected with the user. The connections of the 2-phase circuits are made with flexible tubes. With crankshaft rotation the two CBs develop a pressure differential and a continuous flow with valves constantly open. The operating principle is extended to various types of CB by use of two rotors out of phase by 90° or of four rotors out of phase by 0°, 90°, 180° and 270° in order to obtain 2-phase, 4-phase or multifunction pumps.
A 2-phase pump comprising two identical tubular 2-phase circuits in series made in the corresponding one-way valves and in a tube with axis curved in accordance with a circumference and fastened rigidly to two rotors subjected to periodic oscillatory motion with identical frequency and phase differing by 90° around a shaft fastened to a supporting frame.
A 2-phase pump comprising two identical tubular 2-phase circuits made in corresponding one-way valves and a tube with axis curved in accordance with a cylindrical spiral and fastened rigidly to two rotors subjected to periodic oscillatory motion with identical frequency and phase differing by 90° around a shaft fastened to a supporting frame.
A 2-phase pump comprising two identical tubular 2-phase circuits in series made in the corresponding one-way valves and a tube with axis curved in accordance with a cylindrical spiral with turns superimposed and fastened rigidly to two rotors subjected to periodic oscillatory motion with identical frequency and phase differing by 90° around a shaft fastened to a supporting frame.
A 2-phase pump comprising two identical tubular 2-phase circuits in series made in the corresponding one-way valves and a tube with axis curved in accordance with a frustum of an Archimedean spiral and rigidly fastened to two rotors subjected to periodic oscillatory motion with identical frequency and phase differing by 90° around a shaft fastened to a supporting frame.
A 2-phase pump comprising two identical tubular 2-phase circuits made in the corresponding one-way valves and several frustums flanked by a tube with axis curved in accordance with an Archimedean spiral and rigidly fastened to two rotors subjected to periodic oscillatory motion with identical frequency and phase differing by 90° around a shaft fastened to a supporting frame.
A pump in accordance with one of the above claims characterized in that the connection by means of a flexible tube of the moving inlet and outlet unions of each 2-phase circuit constrained to a rotor with the corresponding fixed unions constrained to a supporting frame is built in such a manner that:
