Abstract

A mixing pump (2) according to the invention comprises: an air duct, referred to as a cool air duct; an air intake (10), referred to as a hot air intake, leading to the cool air duct; as well as means for injecting air from the hot air intake (10) into the cool air duct. The hot air intake (10) leads to a chamber (16) arranged at least partially in the cool air duct. The injection means have at least one opening (30) for connecting the interior of the chamber (16) to the interior of the cool air duct, and means (12) for modifying the flow area through the at least one opening connecting the interior of the chamber (16) to the interior of the cool air duct.
