ABSTRACT:
In a method of manufacturing a pressure control valve, wherein a fuel introduction path and a fuel discharge path are formed in a housing; a spherical valve body mounting portion is formed in the fuel discharge path; and a spherical valve body is mounted to the spherical valve body mounting portion, previously, an annular rib is formed on a diaphragm and an annular groove is formed on the housing. Thereafter, the annular rib of the diaphragm is coupled into the annular groove of the housing to position the diaphragm, and vacuum suction is performed from the fuel introduction path to thereby the pressure in the housing and attract a diaphragm unit to the housing. In this state, a case is put on the housing, and this case is caulked to simultaneously fix the diaphragm and the case to the housing.
