Structures Of Non-Positive Displacement Pumps

Abstract
Automatic safety device, especially designed to control the operation of an electric motor responsible for operating a pump in water or other liquid lifting installations, characterized in that it comprises a tubular chamber, topped by one of its ends in a cylindrical threaded portion, for its fixation to the feeding pipe, while at its opposite end it is hermetically closed by a flexible sheet, capable of yielding by the pressure of arrival of the liquid to the pump, and because it is fixed to said body, following the sheet flexible, a carrier support of a displaceable rod, whose head is close to and facing said sheet and two converging upper conductive lamellae whose free ends are slightly separated and located above the external end of the rod, closing the circuit between said lamellae when the rod is displaced towards them by the flexib sheet i'll even make contact with them.
