Abstract: An equilibrating system connects a top carriage of a piece of artillery and a pivoting mass. The equilibrating system includes a pressurized gas chamber that exerts a force opposing a force exerted by the pivoting mass. The system also includes two mechanical control devices to modify the volume of gas in the chamber to compensate for adjustments in temperature and to modify the speed of adjustment of the volume of gas to compensate for different elevation laying angles.

Abstract: An equilibrating device for a gun having an oscillating mass mounted on a movable top carriage includes a gas chamber, a laying mechanism and an equilibration rod. The gas chamber contains a gas under pressure. The laying mechanism is connected to a gun and orients the oscillating mass with respect to the top carriage in a predetermined position. The laying mechanism has a laying axis and an elongate laying screw extending along the laying axis that applies a laying force to orient the oscillating mass. The equilibration rod is disposed to cooperate with the elongate laying screw and is connected to the gas chamber. The equilibration rod transmits an equilibration force exerted by the gas in the gas chamber along an equilibration axis in a direction opposite the laying force to reduce the laying force. The equilibration force varies in accordance with the laying force based on the predetermined position. As a result, the complexity of the laying mechanism and the equilibrating device can be reduced.
