Abstract: A machine for wrapping ovate articles (P) comprises at least a conveyor mean (2), elongated and positioned horizontally in an operation condition, for the articles (P). The machine (1) comprises also a feeding wheel (25) with rotation axis perpendicular to the conveyor mean (2) and fit to feed this latter with the articles (P) roughly rolled up in wrapping sheet.

Abstract: A fuel manifold for the direct injection of fuel into an internal combustion engine comprising a head provided with a number of cylinders, a number of injectors, each of which is connected to the fuel manifold and is adapted directly to inject the fuel into a respective cylinder, and an intake manifold, which is connected to the head in order to supply fresh air to the cylinders, the fuel manifold being formed by a single monolithic body which is made from thixotropic aluminum by means of a pressure die casting process and comprises a supply duct adapted to distribute the fuel to the injectors, and a flange disposed laterally to the supply duct, the flange being adapted to be secured by a plurality of screws to the head of the engine and comprising a number of coupling members each of which is adapted to bring a respective cylinder into communication with the intake manifold.

Abstract: A wrapping machine for wrapping chocolates and similar products (100) with a wrapping material (101), includes an unwinding and cutting group (6) and a feeding group (10), fit for feeding an elevator group (5) respectively with a portion of the wrapping material (101) and a respective product (100). Said associated wrapping material portion (101) and respective product (100), are provided from said elevator group (5) to a wrapping head (2) to mate a folding group (3) wrapping the product before the transfer of the wrapped product to an outlet group (7). The wrapping head (2) has at least eight gripper means (4) for the product (100) associated to the wrapping material portion (101); such gripper means (4) being radially and angularly equidistant. The folding group (3) includes a plurality of folding modules, at least first (31), second (32) and third (33), positioned around the wrapping head (2) and fit to fold the wrapping material portion (101) around the product (100).

Abstract: Coupling system between engine head, injector and fuel manifold in which the head has a seating designed to house the said injector, whilst the fuel manifold extends above the head, and is connected to the injector through a bush projecting from the fuel manifold; the injector being coupled to the said seating by means of a ball coupling; the fuel manifold being rigidly secured to the head of the engine, and an opposing spring being interposed between the fuel manifold and the said injector to compress the injector inside the seat.

Abstract: The manifold supplies fuel under pressure to a series of fuel metering and atomizing valves, and comprises a first tubular body provided with a series of connections for the valves; a second tubular bodyarranged approximately coaxially inside the first tubular body to define between these bodies a channelfor supplying the fuel to the connections; a first member arranged so as to close off a first axial end of the first tubular body; and a second member arranged so as to close off a second axial end of the first tubular body. The chief characteristic of the manifold lies in the fact that the second member comprises a wall which closes off said first tubular body and that this wall is made in one piece with the first tubular body.
