Patent number: 9856844Abstract: A fuel pump for a direct injection system having: a pumping chamber; a piston, which is mounted in a sliding manner on the inside of the pumping chamber; an intake channel, which originates from a wall of the pumping chamber and has a housing portion; an intake valve, which is inserted into the housing portion of the intake channel; and a locking ring nut with an annular shape, which is threaded and is screwed into the housing portion of the intake channel so as to strike against the intake valve; the housing portion has an annular abutment, which reduces the diameter of the housing portion and against which the intake valve strikes; the locking ring nut is screwed into the housing portion with a tightening force that is sufficient to determine a plastic deformation of the annular abutment against the intake valve.Type: GrantFiled: April 27, 2016Date of Patent: January 2, 2018Assignee: MAGNETI MARELLI S.p.A.Inventors: Michele Petrone, Enrico Vezzani, Massimo Mattioli

Patent number: 9822751Abstract: Fuel pump for a direct injection system provided with a common rail. The fuel pump has a pumping chamber defined in a main body; a piston which is mounted in a sliding manner inside the pumping chamber to cyclically vary the volume of the pumping chamber; an intake channel which originates from a wall of the pumping chamber; an intake valve which is coupled to the intake channel; a delivery channel which originates from a wall of the pumping chamber; a delivery valve which is coupled to the delivery channel; and an actuating spring which has a plurality of turns having a pitch that varies between the turns and that is coupled to the piston so as to push the piston towards a maximum volume or minimum volume position of the pumping chamber.Type: GrantFiled: September 8, 2015Date of Patent: November 21, 2017Assignee: Magneti Marelli S.p.A.Inventors: Enrico Vezzani, Michele Petrone, Luca Mancini

Patent number: 9322374Abstract: The present invention relates to a fuel injector. The fuel injector is provided with an injection nozzle, an injection valve, and an electromagnetic actuator. The injection valve has a movable needle to adjust the flow of fuel through the injection nozzle. The electromagnetic actuator is adapted to move the needle between a closing position and an opening position of the injection valve and is provided with a movable plunger which is mechanically connected to the needle and has at least one feeding through hole for the passage of fuel towards the injection nozzle. The plunger is provided with a hydraulic type braking device, which is coupled to the feeding hole and hydraulically dissipates kinetic energy to slow down the opening stroke of the needle when the needle moves towards the opening position of the injection valve.Type: GrantFiled: April 17, 2014Date of Patent: April 26, 2016Assignee: MAGNETI MARELLI S.P.A.Inventors: Stefano Petrecchia, Massimo Lolli, Massimo Mattioli, Enrico Vezzani, Daniele De Vita

Patent number: 9127631Abstract: A fuel pump for a direct injection system provided with a common rail; the fuel pump has: at least one pumping chamber defined in a main body; a piston which 5 is mounted sliding inside the pumping chamber; a suction channel connected to the pumping chamber and regulated by a suction valve; a delivery channel connected to the pumping chamber and regulated by a delivery valve; and a high pressure connection, which is welded by a ring weld 10 to a wall of the main body at the delivery channel, has the function of allowing a connection to a supply duct that feeds the fuel under pressure to the common rail, and has internally a passing through channel through which the fuel coming from the delivery channel flows 15 towards the supply duct.Type: GrantFiled: May 16, 2011Date of Patent: September 8, 2015Assignee: MAGNETI MARELLI S.P.A.Inventors: Michele Petrone, Enrico Vezzani, Massimo Mattioli
