<p>Disclosed is a pressure wave supercharger (10) equipped with a housing (11) provided with a housing chamber (13) that houses a rotor (12) in a manner rotatable around an axis (Ax) and with an exhaust-side wall (16a) having open exhaust introduction ports (19) and exhaust discharge ports (20) that is disposed in the housing chamber (13) in a manner facing one end (12a) of the rotor (12), wherein: the rotor (12) is equipped with a shaft (23) supported by the housing (11) in a manner rotatable around the axis, a plurality of dividing walls (25) disposed in a manner extending from the shaft (23) in the radial direction and extending in the axis direction from the one end (12a) to the other end (12b) of the rotor (12), and a partitioning member (26) that is disposed in the space between adjacent dividing walls (25) and divides the space into an inner cell (27) and an outer cell (28) by extending from the one end (12a) to the other end (12b) of the rotor (12); and an exhaust-side groove (29), which is formed in a manner overlapping the trajectory (Tr) drawn by the partitioning member (26) during the rotation of the rotor (12) when viewed from the axis direction and is depressed in a direction away from the rotor (12), is provided in the exhaust-side wall (16a).</p> |
