Description
前記供給ポートから供給された前記圧力流体の作用下に負圧を発生させる真空発生機構と、
前記真空ポートに供給される前記圧力流体の圧力を負圧状態と正圧状態とに切り換える供給弁及び真空破壊弁を有する切換弁部と、
前記真空ポートと前記真空発生機構との間に設けられ、前記真空ポートと大気との連通状態を切換可能な大気導入弁と、
前記本体部に設けられ、前記負圧状態から前記正圧状態へと切り換える際に前記真空ポートに前記圧力流体を供給する真空破壊用ポートと、
を備え、
前記大気導入弁は、負圧が発生した負圧状態において弁閉状態となると共に、前記負圧状態が解除された正圧状態において、前記切換弁部の切換作用下に供給されるパイロットエアによって弁開状態となり、前記真空ポートと大気とを連通させることを特徴とする。
