Definitions

the mixer device comprises guide means for the flow introduced into it which are of the centripetal type, that is to say, are designed to guide the flow, admitted in a position spaced apart from the axis X, in the direction of said axis with a substantially centripetal movement, towards the intake section 3a, as will become clear from the following detailed description.
the reference A indicates the attachment region of the conduit which feeds the air from outside to the mixer, having a "segment" configuration extending along part of the circumferential profile of the conduit 5.
