An electromagnetically-controlled fuel injection valve for diesel engines includes an electromagnetic metering valve which controls communication between a control chamber supplied with fuel under pressure through an inlet hole, and a discharge hole. The solenoid metering valve includes a ball obturator movable in a cavity of the body defined by two annular valve seats of which the first defines the discharge hole and the second communicates with the inlet hole. The cavity is in communication with the control chamber through lateral passages. The ball obturator is kept in a closed position against the second seat by means of an electromagnetically-operated axial push rod.

Electromagnetically-controlled fuel injection valve for I.C. engines

A pump with a body formed by two elements sealingly clamped together, between which is defined a central chamber in which a drive shaft carrying an eccentric is rotatably mounted. A plurality of cylinders which open into the central chamber are arranged radially around the shaft in one element of the body, and pistons which cooperate with the eccentric are slidably mounted therein. These cylinders are in communication with a supply chamber defined between the first and second elements. The supply chamber is annular in shape and is formed in a position radially outside the central chamber. At least one sealing member separates the supply chamber from the central chamber. At least one passage is formed in one of the elements to put the supply chamber into communication with the central chamber. An electrically-controlled device controls the flow of fluid through the passage in a predetermined manner.
