That is, since the fluid on the discharge side is a two-phase flow containing a large amount of cooling oil, the silencer 8 is installed downstream of the discharge-side gas-liquid separator 6 in order to prevent the cooling oil from staying in the silencer 8. It is inevitable to reduce the pressure pulsation immediately after the discharge side, that is, it is insufficient for the measure against the noise and vibration problem.
