Abstract
Liquid fuel pump, of the type described, which comprises in combination: a cylindrical chamber arranged parallel to a tangent to the annular cam and in which the piston is housed by a liquid and which is provided with a cylindrical bore; a valve part, cylindrical, housed in the perforation of the piston and penetrating in the manner of a piston, in an extension of the chamber; a first spring acting on the piston in the direction of moving this piston toward the extension of the chamber; a second spring acting on the valve in the same direction; a first supply conduit through which, in the extension of the chamber and in order to operate the valve, liquid fuel is introduced at a pressure that, at least in part, depends on the speed of the engine; a second duct, at least, by which a liquid is introduced into the annular space between the valve and the portion of the chamber adjacent to its extension, when the valve and the piston are in a determined relative axial first position; a return valve to prevent the liquid from returning from said annular space to its supply source and an outlet conduit, by which the liquid can pass from said annular space, to an outlet of the chamber, when the valve and the piston occupy a second relative axial position, determined.
