ADJUSTING DEVICE Russian patent published in 2009 - IPC F16K3/02 F16K31/50 F16K47/02 

FIELD: mechanical engineering.

SUBSTANCE: adjusting device consists of two flat slide valve, located in common casing. Slide valves allows co-axial passage openings. Drive is implemented in the form of one spindle. On it there are two threaded sections with left-handed thread on top section and right - on bottom. Both threaded sections are connected to reciprocal threads. The latter provide simultaneous movement of both slide valves in the opposite direction. One flat slide valve from the side of drive is connected to rod, and other - to additional rod. Rod is motionless fixed to reciprocal thread, connected to the left-handed thread on top section of spindle, and additional rod - to reciprocal thread, connected to right-handed thread on bottom section of spindle. Both threads' pitch is similar.

EFFECT: reliability growth and durability increasing of operation of adjusting device.
