【 摘 要 】

The feasibility to use the ring elastic valve in volumetric-type hydrohammers is substantiated. The relationships of impact power versus the ratio of working area, diameter and length of interchamber throttle are determined by applying a simulation model of hydrohammer mechanism. Rational parameters of the study mass-size dimensional-type hydraulic hammers are selected.
