Abstract

PURPOSE:To ensure the follow-up of the secondary pressure despite a high frequency of the input of an external reciprocating input means by opening an air releasing valve to discharge the pressure out of a pilot pressure room when a pilot valve is moved toward its closing direction by the external reciprocating input means. CONSTITUTION:When a measuring capsule 21 is reciprocated with rotation of a flange cam 28, the secondary pressure which varies in response to the reciprocating motion of the capsule 21 is obtained through a secondary pressure extracting port 13 regardless of the value of the primary pressure obtained at a primary pressure supply port 12. Then an air releasing valve 50 is added to a housing 11b so that the air is quickly discharged out of a pilot pressure room 35 after the valve 50 is opened in case the capsule 21 rises higher than its middle position. Therefore the rising speed of a floating piston 31 is never reduced the remaining air pressure in the room 35. As a result, the satisfactory secondary pressure is secured at the port 13 despite a short rise/fall cycle of the capsule 21.
