EXPANSION MUFFLER, REFRIGERATING CYCLE CIRCUIT USING THE MUFFLER, AND A METHOD OF MANUFACTURING THE MUFFLER

摘要

PPROBLEM TO BE SOLVED: To provide an economical and highly reliable expansion muffler reducing the number of pulsating waveforms of fluid to reduce vibration and noise. PSOLUTION: This expansion muffler comprises an inlet port for flowing the fluid therein, a muffler body expanding the fluid allowed to flow therein through the inlet port, and an outlet port flowing out the fluid from the body after reducing the pressure thereof. The muffler body comprises muffler chambers formed integrally with each other through a pressure-reducing communication hole for reducing the pressure of the fluid and having different lengths.
