PURPOSE: To suppress the generation of noise by a method wherein a boundary end arranged in the outlet region of a shield body is formed at a given angle, in a device provided with a cross piece-shaped shield body located between an opening for an outlet and an opening for an inlet. CONSTITUTION: An annular passage blower 1' sucks air through an opening 8' for an inlet through operation of a vane 3'a, corresponding to an annular passage 4' approximately in a semicircular shape through rotation of an impeller 3' having a number of vanes 3'a and introduces it in the shape of a helical flow in the passage 4'. After air is compressed by the vanes 3'a, it is discharged through an outlet opening 9'. A crosspiece-shaped shield body 16' is arranged between the two openings 8' and 9'. In this case, the shield body 16' has a boundary end 12' in an outlet region 26. This boundary end 12' is surrounded between a passage inner peripheral end 6' and a vane end part 3'c and has an angle α of at least 25 deg. and the angle is increased in an outlet direction.

PURPOSE: To reduce noises by disposing a muffler insert in the region of an exhaust gas exhaust port and deviding exhaust gas flow into parts flows, in a heater to discharge high temperature combustion gas generated in a combustion chamber provided with a burner after passing the gas through a heat exchanger surrounding the burner. CONSTITUTION: A heater 1 for an automobile is provided with a spray type burner having a fuel injection body 2, and a vortex body 3 is disposed at a given distance from the fuel injection body 2. A burner insert 5 is disposed in the downstream of the vortex body 3, intruded into a combustion chamber 7 consisting of combustion pipes 6. The combustion pipe 6 is surrounded by a heat exchanger 8, and the heat exchanger 8 is surrounded with an external casing 9. Combustion gas generated in the combustion chamber 7 flows through a space 18 between the combustion pipes 6 and the heat exchanger 8 and flows out through an exhaust gas exhaust port 12. In this case, a muffler insert 13 having two hollow bodies 14 is disposed in the discharge port 12, to achieve in particular, silencing of low frequency combustion noise.
