SELF-ADJUSTING, GEOMETRICALLY COMPACT VALVE ASSEMBLY Russian patent published in 2018 - IPC G05D16/16 

FIELD: machine engineering.

SUBSTANCE: self-adjusting valve assembly comprises a valve body having an inlet portion for connecting to reservoir in the lower zone and an outlet for connecting to pipeline system in the upper zone, a piston moving in the valve body along the first axis between the open position which provides fluid communication between the inlet section and an outlet, and a closed position which interrupts said fluid communication, the piston having an upper end portion and the lower locking portion. The assembly also comprises a spring-type module coupled to the piston and the valve body and dynamically interacting with the piston, at least after activation of the trigger device valve (Act) and during the entire self-adjustment cycle of the valve which causes positioning of the valve between the open position and the closed position, providing fluid communication between the inlet section and the outlet under the controlled outlet pressure. The spring-type module is placed under the lower locking section of the piston.

EFFECT: due to displacement, the dimensions of the valve assembly can be significantly reduced.
