徴とする減圧弁のパイロツト弁構造。 A stem guide hole that penetrates the stem guide in the vertical direction is formed, a pilot valve port is formed at the lower end of the stem guide hole, and a pilot valve body that opens and closes the pilot valve port from below is arranged to allow fluid to flow from the pilot valve port. A horizontal hole is opened so as to intersect with the stem guide hole for allowing the flow to flow to the upper surface of the piston,
In a pilot valve portion of a pressure reducing valve in which a pilot stem having a lower diameter smaller than an upper diameter is slidably inserted into the stem guide hole, a large space is provided at a portion where the stem guide hole and the horizontal hole intersect. 1. A pilot valve structure for a pressure reducing valve, characterized in that a large diameter portion and a small diameter portion of the pilot stem are connected within the valve chamber.
