Here, the function of the diaphragm (D) will be described. The flow of air from the orifice contracts along the flow as shown in FIG. 2, and the cross section of the flow changes. Upstream point A
The pressure at the downstream point C is Pl, the pressure at the point B immediately after the orifice is Ps, and the pressure at the downstream point C is Ps.
When the pressure of 1 is gradually decreased, the flow velocity at the point B increases. As the pressure at point B decreases, the P
When 1 decreases to a certain pressure, the flow velocity and pressure at point B take a constant value, and remain unchanged even when Pl is further reduced.

This is because the flow velocity at point B has reached the speed of sound.
This is because the flow rate cannot be further increased. The condition at which the flow velocity at the point B becomes a sonic velocity is determined by the ratio of the upstream and downstream absolute pressures, and this ratio is called a critical pressure ratio, and Ph / Pl =
