Abstract

"Improvements in pumps for liquids", characterized by a control device for variable control pumps, in which the pumping mechanism contains a mobile element to vary the effective flow rate of the pump and a fluid motor to move the mobile element in a direction, against a driving force in the opposite direction and comprising a valve for controlling the flow of fluid to and from said engine, and in that said valve contains a moving valve element between a first and a second position, to connect the fluid motor to the outlet of the pump or to the emptying; means for driving the fluid under pressure, dependent on the pressure in the fluid motor that drives the valve element towards one of the positions mentioned; and a variable elastic drive that tends to move the valvular element towards the second mentioned position.
