Device for supplying a mixture of fuel and air to a manifold of an internal combustion engine

摘要

The device substantially comprises an upper body in which is formed a first perforation in communication with an air intake opening and delimited by a first conical surface and a support element for a fuel atomisation and metering valve having a tubular form and connected to the first conical surface by means of a pair of ribs disposed substantially in the plane which contains the axis of the first conical surface. The device further includes a lower body in which is formed a second perforation delimited by a second conical surface coaxial with the first and which is in communication with a mixture supply opening, the cone angle of the second conical surface being greater than that of the first conical surface.
