摘要:
A pressure reducing apparatus (10) includes a body (12) being equipped with a first side port (20) through which a pressure fluid is supplied and a second side port (22) through which the pressure fluid having been reduced in pressure is discharged. Further, a feedback passage (64) is formed, which establishes communication between the second side port (22) and a third diaphragm chamber (90) that faces toward a pilot valve (93). Additionally, a pressure fluid that flows through the second side port (22) is introduced through the feedback passage (64) into the third diaphragm chamber (90), whereby a third diaphragm (78) is pressed upwardly against an elastic force of a second spring (82) into equilibrium.
