Pump operating on rotational inertial forces with proportional delivery and head inversely proportional to the number of active circuits and balancing of the moments of the inertial forces transmitted to the pump supporting frame and generation of rotor oscillatory motion

Abstract

The parts for implementing the invention of the pump with high delivery and low head are illustrated in FIG. 1/10 which shows a tubular circuit bent in accordance with a circumference occupied by way of example by four 2-phase circuits fastened rigidly to a rotor. Each 2-phase circuit consists of a counterclockwise and a clockwise circuit whose direction is defined by two one-way valves each arranged at the beginning of the associated circuit. After the pump inlet the liquid is distributed through the inlets of the 2-phase circuits to the circuits C i e C i′ . The forces of inertia stressing the liquid mass m c =m 0 /N c of each circuit (where m c is the total mass relative to the circumference and N c is the number of circuits into which it is divided) are proportionate to the same mass m c . Accordingly the acceleration of m c and the corresponding mean velocity V c are independent of m c . As the cross section of each circuit is constant it follows that the delivery Q c is also independent of N c while the sum of the deliveries is Q 0 =N c Q c where Q 0 is the delivery at the inlet E 0 of the pump. The force of inertia f c which stresses m c is f c =f 0 /N c , where f 0 is the force of inertia relative to the summation of the absolute value of the forces stressing the circuits C i . “Pump operating on rotational inertial forces with proportional delivery and head inversely proportional to the number of active circuits; also balancing of the moments of the inertial forces transmitted to the pump supporting frame and generation of rotor oscillatory motion”
