2. The vapor-liquid separator according to claim 1 ,
wherein said storing part comprises a housing for covering said separator main body, and
wherein said communicating part is a communication pipe which is provided on an upstream side of a vapor-liquid separation region of said separator main body and is communicating with an interior of said housing.
3. The vapor-liquid separator according to claim 2 , further comprising a spiral plate configured for applying a swirling force to a vapor-liquid mixed fluid flowing toward an upstream side of a vapor-liquid separation region of said separator main body in said housing.
4. The vapor-liquid separator according to claim 2 , further comprising an intake part which is provided on said storing part and is configured for suctioning a vapor-liquid mixed fluid existing outside of said storing part.
5. The vapor-liquid separator according to claim 4 ,
wherein an opening area of said intake part is smaller than an opening area of said introducing part.
6. The vapor-liquid separator according to claim 2 , further comprising a baffling part which is provided in said storing part and is configured for inhibiting a liquid stored in said storing part from flowing backward to said liquid discharging part.
7. The vapor-liquid separator according to claim 6 ,
wherein said baffling part has a tapered surface inclined relative to the horizontal face.
8. The vapor-liquid separator according to claim 2 ,
wherein said vapor-liquid mixed fluid comprises a blow-by gas.
9. The vapor-liquid separator according to claim 1 ,
wherein said storing part is a storage tank to which said liquid discharging part of said separator main body is connected, and
wherein said communicating part comprises a communication pipe configured for communicating said storage tank with an upstream side of a vapor-liquid separation region of said separator main body.
10. The vapor-liquid separator according to claim 9 , further comprising an intake part which is provided on said storing part and is configured for suctioning a vapor-liquid mixed fluid existing outside of said storing part.
11. The vapor-liquid separator according to claim 10 ,
