APPARATUS FOR SUPPRESSING LIQUID PULSATIONS AT CYCLIC OPERATION OF HYDRAULIC SYSTEM Russian patent published in 2002 - IPC

FIELD: suppression of liquid pulsations at periodical operation of hydraulic system. SUBSTANCE: apparatus includes cylindrical housing with adaptor for inlet-outlet of liquid and hollow piston arranged in said housing. Apparatus also includes piston in the form of float and intermediate vessel connected with above mentioned adaptor, having unions for inlet-outlet of liquid and for joining with pressure pipeline. Cylindrical housing is in the form of vertically arranged branch pipe with closed upper end. Along height of said branch pipe two sleeves are arranged. Height of low sleeve is no less than height of float and its inner diameter is more than that of upper sleeve. Sleeves are mounted with gap relative to float being in idle position. On end of vertically arranged branch pipe there is seat for float having ducts for communicating cavity of intermediate vessel through adaptor for inlet-outlet of liquid with cavity of vertically arranged branch pipe. EFFECT: enhanced operational reliability of apparatus. 1 dwg
