Abstract

A two-stroke engine of mixed induction type comprises a first duct (19) for direct induction or intake of the mixture into the cylinder chamber (16) and at least one further duct for induction or intake by reeds, the further duct(s) is (are) provided in the cylinder and opens (open) into the cylinder chamber (16) and/or into the transfer ducts (24). The engine is equipped with a reed valve also forming the subject of the invention, and comprising a free central passage (52) and at least one further passage (54) provided with reed actuator (55).
