Device for supplying air to a multiple-cylinder engine head

A device for supplying air to a cylinder head of a multi-cylinder engine including two banks of air inlet ducts leading toward the cylinders, the ducts including inlet orifices, the air supply device comprising:

• one first and one second manifold, the manifolds positioned or configured to be positioned and fixed on the cylinder head, along the inlet orifices of the air inlet ducts, each manifold comprising, at a first end, an air orifice;
• a splitter comprising at least two air orifices positioned or configured to be positioned facing the air orifice of the respective manifolds, the splitter and the manifolds comprising, in immediate surroundings of their orifices, to ensure required relative positioning and the joining-together:
• of:
• the splitter and one of the manifolds, positioning first complementary means with sliding pivoting along an axis of engagement between the splitter and the manifold, with substantially play-free precise relative centering, along the axis, the possibility of pivoting about the axis and translational movement along the same axis,
• and, of:
• the splitter and the other manifold:
• positioning and pressing second, complementary means comprising:
• additional pressing means, and
• locating means for preventing pivoting about the axis of engagement once a required relative angle of pivoting needed to ensure the required positioning between the splitter and the manifolds has been reached,
• and fixing third complementary means for immobilizing the splitter and the corresponding manifold pressing against one another at the required angle of pivoting.
