Abstract
The device includes a main receptacle (1) having an overflow pipe (2) and a secondary receptacle (9) mounted so as to be freely movable in the vertical direction inside the main receptacle (1). The inner space of the secondary receptacle (9) communicates with a drainage pipe (8) for fluid lost by the hydraulic installation. The secondary receptacle (9) floats in the fluid contained in the main receptacle (1). The immersion level of the secondary receptacle (9) increases, depending on the amount of lost fluid received by the secondary receptacle (9), and the supply of fluid from the main receptacle (1) is caused by the immersion of the secondary receptacle (9).
