HYDRAULIC LINEAR IMPACT TOOL

摘要

Hydraulic Linear Impact Tool A hydraulically operated impact tool is provided for performing land-based or undersea tasks including hammering, chipping, scraping, punching, and cutting. The tool's features include a spring (preferably hydroelastic) for storing impactstroke energy, a configuration of valves which eliminates flow in the supply and return lines during the impact stroke, and a control approach which provides operator selection of either single-blow or continuous-cycling operation.
