  • Publication number: 20200080189
    Abstract: A flow resistant part having a rod shape is disposed in a raw liquid introduction path in a manner such that the raw liquid is sprayed onto a vaporization plate to reduce the conductance of the raw liquid introduction path with respect to the raw liquid. Because the pressure on an outlet side of the liquid mass flow controller is increased, and the pressure difference from the pressure on the inlet side of the liquid mass flow controller is reduced, the occurrence of cavitation can be prevented. A plurality of the flow resistant parts can be provided.
