Abstract

The apparatus for balancing bodies of revolution includes balancing tanks located peripherally within the body of revolution. Mounted coaxially with the body of revolution is a distributing chamber with conduits hydraulically connecting said distributing chamber with the balancing tanks. The ends of the conduits are disposed inside the distributing chamber and are equidistant from the geometric axis of the body of revolution. Resilient diaphragms are fixed on the wall of the balancing tanks, at the outlet of the conduits. The apparatus for balancing bodies of revolution also comprises a liquid supply source hydraulically associated with the distributing chamber and made in the form of a chamber with a diameter smaller than that of the distributing chamber, and said chamber being located centrally within the body of revolution and forms a tight cavity with the distributing chamber and the portion of the balancing tank defined by the resilient diaphragm.

Claims

1. An apparatus for balancing a body of revolution with a vertical axis of rotation, comprising:

a plurality of balancing tanks located peripherally within said body of revolution;

a distributing chamber, having an annular shoulder, mounted coaxially with said body of revolution, and hydraulically connected with said balancing tanks;

conduits of said distributing chamber, made in the annular shoulder of said distributing chamber and hydraulically connecting said distributing chamber with said balancing tanks;

one of the ends of said conduits being located inside said distributing chamber and equidistant from said axis of rotation of said body of revolution; and

the other of said ends of said conduits being located inside said balancing tanks;

resilient diaphragms fixed on walls of said balancing tanks at the other ends or outlets of said conduits;

a balancing liquid supply source hydraulically associated with said distributing chamber;

a chamber of said liquid supply source, having a diameter smaller than the diameter of said distributing chamber and located centrally within said body of revolution; and

said chamber of the liquid supply source, the distributing chamber and part of said balancing tanks defined by said resilient diaphragm, and forming a fluid tight cavity.

2. An apparatus for balancing bodies of revolution according to claim 1, further comprising:

bypass channels for returning the balancing liquid from said distributing chamber back into said liquid supply source as said resilient diaphragm compresses and closes the other ends or outlets of said conduits in said balancing tanks, and said bypass channels hydraulically connecting said distributing chamber with said liquid supply source.
