Abstract
PURPOSE: To obtain very easy and efficient control of pressure reduction by introducing fluid into fluid chambers by the operation of a pilot switch valve for using a main valve for the common use to intercept an inlet route and an outlet route.
CONSTITUTION: When a pilot switch valve 48 is operated to the left position, an axle member 26 of a main valve 21 is operated axially by a spring 33 on the basis of the pressure in a fluid chamber 27, and separated from a valve seat 20 for issuing pressure fluid to an outlet route 3. The pressure fluid issued to the outlet route 3 is partly sent to fluid chambers 29, 23, and a pilot route 8 via a connecting hole 31 to give operation to a pressure control valve 35. When the fluid pressure is raised over a set value, since the fluid in the fluid chamber 23 is discharged to a low pressure part, the pressure in the fluid chamber 23 is lowered by a throttle 34, and the main valve 21 is operated to a balanced position of operational forces of a spring 33 and a pressure difference given between fluid chambers 23 and 29. Consequently, the valve seat 20 is opened, and the fluid from an inlet route 2 is controlled in pressure reduction, and discharged to the outlet route 3.
