Abstract

Improvements in the automatic liquid level regulating installations, according to which a mercury switch is provided, comprising an elbow lever mounted so that it can swing freely on a support integral with a base provided with fixing means to the base of the tank in question, whose lever at one end is related to a vertical rod, located inside the tank and provided with two stops, on which it can freely slide between the limit positions determined by the latter, a float that in the indicated limit positions determines the tilting of the one in one or the other direction, having provided at the other end of the lever the hermetically sealed ampoule containing a certain amount of mercury and in one of its extremities there are two contacts, which can be connected to each other, by that, by adopting the expressed blister a certain inclination, as a result of the tilting of the lever; everything so that when the level of liquid inside the tank reaches a certain minimum limit, the float by its own weight determines the tilting of the lever, and therefore of the ampule fixed to it, establishing the connection between the two referred contacts, which close the control circuit of a contactor that determines the closing of the supply circuit of the electric pump that supplies liquid to the tank, and when the indicated level reaches a predetermined maximum value, the expressed buoy forces the assembly to tilt in opposite direction, making the opening of the circuit.
