Abstract

An alternative self-regulating pump for liquids, in particular for fuel injection in an internal combustion engine, which includes a main piston with reciprocating movement in a main cylinder that communicates with a discharge duct, the opening and closing of said discharge duct being regulated by a shuttle piston acting as a movable sliding valve in a housing provided with at least one cylindrical part, said shuttle piston being moved in one direction by a pressurized liquid delivered in a chamber of variable volume constituted between the shuttle piston and its housing, said liquid under pressure periodically brought to said chamber by an alternative auxiliary pump moved in synchronism with the main pump and this shuttle piston being forced to go in the other direction by elastic means against the action of a brake system consisting of a passage regulated by strangulation existing in a part of a drainage or outlet circuit through which a liquid delivered by the shuttle piston circulates during the return stroke thereof driven by said elastic means, said pump being characterized by the fact that the delivery of the auxiliary pump communicates directly only with said variable volume chamber of the shuttle plunger housing.
