Title: Pump consisting of a mechanism transmitting to a tubular circuit system periodic rotational inertial forces developing in the liquid contained therein continuous pressure and flow

Abstract: 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 and; 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 or of four rotors out of phase by,, and in order to obtain 2-phase, 4-phase or multifunction pumps.
