摘要： A diaphragm-type solenoid valve has a valve body 3 fixable onto a base, a diaphragm 4 for opening and closing a valve seat 13 provided at an inner end of a second port 12, a plate 5 for forming a driving chamber 14 between the plate 5 and the diaphragm which is sandwiched between the plate 5 and the valve body 3, and a pilot valve 6 for supplying pilot fluid pressure to the driving chamber 14. A disc 20 is enclosed in a portion of the diaphragm facing the port 12, a sealing rib 21 corresponding to the valve seat is provided, and cushion projecting portions 22 and 23 for coming in contact with cushion receiving portions 32 and 33 on the plate 5 are formed behind the portion where the disc 20 is enclosed.
