PRESSURE STABILIZER FOR HYDRAULIC SYSTEM Russian patent published in 2005 - IPC

FIELD: hydraulics.

SUBSTANCE: pressure stabilizer comprises housing with inlet and outlet branch pipes, central perforated pipeline mounted inside the housing to define ring-shaped chamber between the outer side of perforated pipeline and inner side of the housing, and damping members with flexible separators uniformly arranges over the periphery of the housing . The separators define liquid and gas spaces that are connected with the chamber and external source of compressed gas. The stabilizer is provided with pressure accumulator. The housing has hydraulic collector connected with the pressure pipeline through the throttle member at the pump inlet. The central pipeline is perforated at an acute angle to the flow. The gas spaces of the damping members are in communication with the drain pipeline provided with electromagnetic valve and hydraulic valve connected in series. The pressure accumulator is connected with the drain pipeline between the valves. The control space of the hydraulic valve is in communication with the pressure pipeline at the pump outlet.

EFFECT: enhanced reliability.
