Embodiment Construction
[0039] Below, refer to Figure 1 to Figure 7 A muffler for a supercharger according to one embodiment of the present invention will be described.
[0040] Figure 7 It is a vertical cross-sectional view showing a structural example of an exhaust turbocharger provided with the turbocharger muffler of the present invention, and the turbocharger muffler of the present invention can be applied to such an exhaust turbocharger 10 .
[0041] The illustrated exhaust turbocharger 10 is installed, for example, in an unillustrated marine diesel engine (for example, a low-speed two-stroke diesel engine), and is connected to an air supply manifold that communicates with the inside of a cylinder liner (not illustrated) constituting the marine diesel engine. (not shown) Compressed air is supplied.
[0042] Such as Figure 7As shown, the exhaust turbocharger 10 is constructed by integrally fastening a gas inlet housing 11 , a gas outlet housing 12 , a bearing stand 13 , and an air guide ho...

The present invention provides a muffler for a supercharger capable of reducing manufacturing costs while ensuring sound absorption performance. The supercharger muffler (30) is installed on the upstream side of the inlet of the intake air introduction path that introduces the intake air for compression by the compressor unit, and is used to absorb intake noise, and is configured to include an intake air inlet opening ( 32), which is formed on the outer peripheral surface of the housing (31) in a substantially cylindrical shape; the suction air flow path, which converts the suction air introduced from the suction air inlet opening (32) by approximately 90 degrees to guide the suction Air introduction path; suction air outlet opening (34), which is formed on one end face side of the housing (31); sound absorbing cylinder (40), which is inserted from the outer peripheral side of the housing and mounted on the suction air inlet opening (32); and support A plate (50) having an air circulation hole (51) substantially concentric with the sound absorbing tube (40) and fixedly supporting the sound absorbing tube (40) inserted into a predetermined position of the suction air inlet opening (32).
Description
technical field [0001] The present invention relates to a muffler for a supercharger that is suitable for, for example, large diesel engines for ships and power generation. Background technique [0002] Conventionally, a supercharger that compresses combustion air of an internal combustion engine and forcibly sends high-density air into a combustion chamber is known, and is widely used, for example, in large diesel engines for ships and power generation. In such a supercharger, a compressor that compresses combustion air and a supercharger turbine that is a driving source of the compressor are housed coaxially in a casing and rotate integrally. It should be noted that the turbocharger turbine is driven by the energy of the exhaust gas of the internal combustion engine. [0003] In such a supercharger, in order to eliminate the noise generated by the compressor wheel, for example, a muffler for a supercharger as disclosed in Patent Document 1 below is used. In this muffler ...
