Claims (1)
ンダの上下のポートを、切換弁に接続するとともに、上
端のポートと切換弁との間に、下のポートに作用する空
気圧よりも低い圧力に減圧する減圧弁と該減圧弁に並列
接続されかつ上のポートからの流れのみを自由とする逆
止弁とを介在したことを特徴とする昇降装置。Attach a load to the rod pointing downwards. Connect the upper and lower ports of the air cylinder that moves up and down to the switching valve, and reduce the pressure between the upper end port and the switching valve to a lower pressure than the air pressure acting on the lower port. An elevating device characterized by interposing a pressure reducing valve and a check valve connected in parallel to the pressure reducing valve and allowing flow only from an upper port.
