20090193763 | FOLDING UNIT FOR PRODUCING SEALED PACKAGES OF POURABLE FOOD PRODUCTS - A folding unit for producing sealed packages of pourable food products from respective packs, each having a main portion folded into a desired shape, and opposite end portions to be folded to form respective folded ends of a relative finished package. The unit has a first folding station, in turn having a first retaining mechanism for securing each pack by a relative first end portion, and a first folding mechanism for folding a relative second end portion of the pack. The unit also has a second folding station located downstream from the first folding station in the traveling direction of the packs, a second retaining mechanism for securing each pack by the relative folded second end portion, and a second folding mechanism for folding the relative first end portion. | 08-06-2009 |
20100205911 | MEMBER AND METHOD FOR FORMING SEALED PACKAGES OF POURABLE FOOD PRODUCTS FROM A TUBE OF PACKAGING MATERIAL - A forming member for controlling the volume of packages of pourable food products formed from a tube of packaging material and sealed at a number of sections of the tube crosswise to an axis of the tube; the forming member having: a main wall which cooperates cyclically with a first portion of the tube extending between two consecutive sections; and at least one flap extending alongside the wall. The flap is movable, with respect to the wall, between a first position, in which it cooperates with a second portion of the tube, extending between the two consecutive sections, to control the volume, between the two consecutive sections, of the package being formed, and a second position, in which it is detached from the second portion. | 08-19-2010 |
20130133291 | MEMBER AND METHOD FOR FORMING SEALED PACKAGES OF POURABLE FOOD PRODUCTS FROM A TUBE OF PACKAGING MATERIAL - A forming member for controlling the volume of packages of pourable food products formed from a tube of packaging material and sealed at a number of sections of the tube crosswise to an axis of the tube; the forming member having: a main wall which cooperates cyclically with a first portion of the tube extending between two consecutive sections; and at least one flap extending alongside the wall. The flap is movable, with respect to the wall, between a first position, in which it cooperates with a second portion of the tube, extending between the two consecutive sections, to control the volume, between the two consecutive sections, of the package being formed, and a second position, in which it is detached from the second portion. | 05-30-2013 |

20100242922 | DIRECT-INJECTION SYSTEM FUEL PUMP WITH A MAXIMUM-PRESSURE VALVE - A direct-injection system fuel pump having: at least one pumping chamber; a piston mounted to slide inside the pumping chamber to cyclically alter the volume of the pumping chamber; an intake channel connected to the pumping chamber and regulated by an intake valve; a delivery channel connected to the pumping chamber and regulated by a one-way delivery valve that only permits fuel flow from the pumping chamber; and a drain channel regulated by a one-way, maximum-pressure valve, which opens when the fuel pressure in the drain channel exceeds a threshold value, and which has a shutter movable along the drain channel, a valve seat engaged in fluidtight manner by the shutter, and a spring calibrated to push the shutter into a position engaging the valve seat in fluidtight manner. | 09-30-2010 |
20110103985 | FUEL PUMP WITH AN IMPROVED DAMPING DEVICE FOR A DIRECT INJECTION SYSTEM - A fuel pump for a direct injection system having: at least one pumping chamber; a piston which is mounted sliding inside the pumping chamber in order to vary cyclically the volume of the pumping chamber; an intake duct connected to the pumping chamber and regulated by an inlet valve; a delivery duct connected to the pumping chamber and regulated by a one-way delivery valve which allows exclusively a fuel flow outgoing from the pumping chamber; and a damping device, which is placed along the intake duct upstream of the inlet valve, and comprises at least one elastically deformable damping body that has internally a closed chamber filled with pressurized gas and composed of two metal plates cup shaped and welded together at their annular edges by an annular weld without interruptions. | 05-05-2011 |
20110108007 | FUEL PUMP WITH REDUCED SEAL WEAR FOR A DIRECT INJECTION SYSTEM - A fuel pump for a direct injection system having: at least one pumping chamber, a piston which is slidingly mounted inside the pumping chamber in order to cyclically vary the volume of the pumping chamber, an intake duct connected to the pumping chamber and regulated by an inlet valve, a delivery duct connected to the pumping chamber and regulated by a one-way valve that only allows outgoing fuel flow from the pumping chamber, and an annular seal, which is placed in a seat made below the pumping chamber around a lower portion of the piston and has the function of preventing fuel leakage along the side wall of the piston. | 05-12-2011 |
20120012084 | Fuel Pump For A Direct Injection System - 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 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 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 towards the supply duct. | 01-19-2012 |
20140312147 | ELECTROMAGNETIC FUEL INJECTOR WITH BRAKING DEVICE - 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. | 10-23-2014 |
