Abstract

See full text

A chamber body is provided, as regions where the liquid flows, with: an upper region including an area from the inner surface of the upper wall to the introduction pipe; a lower region connected to the outlet port; and a connection region connecting the upper region and the lower region. The inner circumferential surface of the upper region has a larger diameter than the inner circumferential surface of the lower region. As a result of diameter reduction from the connection portion relative to the upper region to the connection portion relative to the lower region, an inclined surface is formed on the inner circumferential surface of the connection region.
