    摘要: A Common Rail injection system of an endothermic engine, the injection system including at least one fuel pressure accumulating tank, of the rail type, having an input in fluid communication with a high-pressure pump and a plurality of outputs for feeding corresponding injectors by using pressure regulating means connected and depending on an electronic control unit. Advantageously a virtual pressure sensor includes a fluid-dynamic model of the accumulating tank suitable to estimate and to obtain fluid pressure values used by the electronic control unit for driving the injection means of the Common Rail injection system.

    摘要: A method of generating 2D or 3D maps of MRI T1 and T2 relaxation times by acquiring 2D or 3D MRI gradient-echo images and extracting the T1 and T2 values from the images, wherein MRI images are acquired using a combination of gradient-echo sequences, including a first MRI image acquired using a SSFP-FID (Steady State Free Precession-Free Induction Decay) acquisition sequence; two further images acquired using a Dual-Echo SSFP acquisition sequence; and the T1 and T2 values are extracted for each image pixel or voxel from the corresponding MRI signals.

    摘要: An oil rotary vacuum pump of mechanical type (100) is filled with a requested amount of oil at the end of the manufacturing process, then it is stored and then shipped to the user, letting the user to avoid an operation of introducing the proper amount of oil into the pump. The oil leakage is prevented by securing the suction and/or exhaust ports (3, 17) of the pump, which are sealed by means of a removable sealing member, for instance by means of a membrane (21, 23).
