を特徴とするダイヤフラム式ポンプ。 The inside of the housing is divided into a pump chamber and a spring chamber by a diaphragm whose peripheral edge is held by the housing, and the pump chamber is connected to the discharge port via a discharge side check valve, and is connected to the discharge port via a suction side check valve. The spring chamber houses a return spring that urges the diaphragm toward the pump chamber.One end of the spring is connected to the center of the diaphragm, and the return spring is movable in the axial direction in the spring chamber and supported by the housing. In a diaphragm type pump, the other end of the diaphragm rod is interlocked and connected to a cam via an adjustment mechanism that adjusts the stroke of the diaphragm rod according to the pressure inside the pump chamber.The adjustment mechanism is connected to the housing. A cylindrical push rod with a bottom that is biased toward the side that slides into contact with the cam by a coil spring interposed therebetween, and on which the other end of the diaphragm rod coaxially slides together, and a diameter line between the diaphragm rod and the push rod. a connecting pin extending along the diaphragm rod, an insertion hole drilled in the diaphragm rod with an inner diameter corresponding to the outer diameter of the connecting pin into which the connecting pin is inserted, and a connecting pin protruding from the outer surface of the diaphragm rod. A diaphragm type comprising a pair of adjustment holes drilled in the push rod for locating both ends and having a diameter along the axial direction and a diameter along the circumferential direction of the push rod larger than the diameter of the connecting pin. pump.
