Claims (1)
気圧信号に応じて開口面積が変化する給気弁と、 前記出力室を大気と接続し、入力空気圧信号に
応じて開口面積が変化する排気弁 とを備えたパイロツトリレーにおいて、 前記給気弁と排気弁の少なくとも一方に入力空
気圧信号が変化しても開口面積が一定若しくは変
化率の小さい停留域を設けたことを特徴とするパ
イロツトリレー。[Scope of Claim for Utility Model Registration] A boost pressure chamber to which boost pressure is supplied, an output chamber to output an output air pressure signal, and an opening area that connects the boost pressure chamber and the output chamber, and whose opening area is adjusted according to the input air pressure signal. A pilot relay comprising an air supply valve whose air pressure changes, and an exhaust valve which connects the output chamber to the atmosphere and whose opening area changes according to an input air pressure signal, wherein the air pressure signal is input to at least one of the air supply valve and the exhaust valve. A pilot relay characterized in that even if the air pressure signal changes, the opening area is constant or a stopping area is provided with a small rate of change.
