Document Type and Number:
WIPO Patent Application WO/2005/083272
Kind Code:
A1
Abstract:
Provided are an ejector capable of linearly controlling an ejection flow rate relative to the amount of movement of a needle to enhance its applicability as a whole and a fuel cell system with the ejector. An ejector (24) has a nozzle (46) for jetting fluid, a needle (48) provided coaxial with the nozzle (46) and whose head section (48a) faces the nozzle (46), and needle moving means (49) for axially moving the needle (48) in an advancing and retreating manner. The shape of the head section (48a) of the needle (48) is set such that an opening area (Y) of the gap between the head section and the nozzle (46) and the amount (Z) of movement by the needle moving means (49) satisfy a proportional relationship.
