    摘要: A tank for pressurized gas such as hydrogen, comprises a paste sealant, a sealing envelope, and a base comprising a recess accommodating a neck. A substantially annular external cavity is between a convex surfaces of the neck and a concave surfaces of the recess A substantially annular inner cavity is between a concave surface of the neck and a convex surface of the recess. The paste sealant occupies the annular external and annular inner cavities uniformly and thus ensures the mechanical strength and the gas seal between the sealing envelope and the base. The sealing envelope comprises a body and a neck on the surfaces of which at least two angularly equidistant protrusions extend radially.

    摘要: A heat recovery device comprises a valve body inwardly defining a direct flow path for exhaust gases from an inlet to an outlet, a heat exchanger comprising a flow passage for the exhaust gases emerging in an inlet zone of the valve body, and a gate positioned in the valve body. The heat recovery device comprises a guide wall positioned in the direct flow path at the inlet zone, arranged to guide the exhaust gases from the inlet toward the cutoff section away from the inlet zone when the gate frees the direct flow path, and delimiting at least one orifice to allow the exhaust gases to go to the inlet zone when the gate closes off the direct flow path.
