Abstract

Improved hydraulic ram type pump, comprising a base, a ram body, organs to feed water to said ram body, a pressure fluid reservoir, integral with said ram body, a delivery valve disposed between the fluid reservoir pressure and the body of the ram and intended to allow the passage of water from the body of the ram to the reservoir of fluid under pressure, a leak of excess water that includes an exit opening and a flat plate articulated in a tilting way to the wall internal of the body of the ram, so that when the forward and backward movement of said plate occurs, it will alternately open and close the outlet opening allowing water to escape from the water body and preventing the aforementioned escape in order to initiate the waterhammer effect that drives the water from the ram body towards the pressure fluid reservoir through the valve of impulsion: arranged between said body of the ram and said pressurized fluid reservoir, said arrangement being characterized in that the impulsion valve comprises a set of elements that include a valve stem, a valve piston made of an elastic material and which adopts a shape substantially equal to that of an inverted inverted truncated cone on said valve stem, a series of adjustable counterweights disposed on said valve piston and intended to regulate the operation of this piston, and a spring arranged around the cited valve stem and that contributes to the accuracy and sensitivity of its operation, the aforementioned set of elements being arranged along an opening that has a shape substantially analogous to that of the valve piston, and carrying organs that allow support and sliding inside said valve stem.
