FIELD: process engineering.
SUBSTANCE: invention relates to powder pulsed proportioner. Proportioner comprises powder hopper, tight housing with compressed gas feed channels, spool-valve arranged in said housing to move therein and spool-valve drive. Spool-valve air-operated drive consists of cylinder connected to compressed gas source to accommodate spring-loaded piston coupled via con rod with aforesaid spool valve. Cylinder face wall has a channel to communicate cylinder delivery chamber with compressed gas feed channels, Rod body has through transverse bore arranged on rod length so that, in shifting spool-valve to position of loading measuring vessel, section of said bore gets aligned with cylinder wall channel section.
EFFECT: increased reliability and longer life.
