At this time, read vacuum pressure P1, obtain the suction flow rate from the flow-rate characteristics graph for the ejector that is being used, and render this amount as the leakage of the workpiece.
The inlet pressure obtained in the flow characteristic graph of silencer indicates the pressure (P1) prior to silencer. (Refer to the diagram below.)
When the inlet pressure (P1) is shut off and released, the check valve w, opens and the pressure in the diaphragm chamber q is released into the inlet side (Figure 2). This lowers the pressure in the diaphragm chamber q, and the force generated by pressure regulator spring e lifts the diaphragm.

Inlet pressure (IN) Pressure in diaphragm chamber When the inlet pressure (P1) is higher than the regulating pressure, the check valve w closes and operates as a normal regulator (Figure 1). When the inlet pressure (P1) is shut off and released, the check valve w opens and the pressure in the diaphragm chamber q is released into the inlet side (Figure 2).
