Lamb forced return mechanism with manual hydraulic tools

摘要

(57) Abstract Objective The manual oil which disconnects the electric wire and compresses the sleeve etcIn the pressure type tool, normal resetting manipulation of the needle being simple, the maIt is, to force to the needle, when is and causes the attachment even, big powerWithout requiring at the same time certainty way the forcing resetting is possible easily,It does. Constitution The cylinder chamber which the ram which installs the needle Inlaying entrance is doneWith the oilway which changes the reciprocate of the aforementioned ram between the oil tanksAs the change-over valve mediating/helping facilities is done, on the aforementioned cylinder chamber bottom the small diameterForming the sub- cylinder chamber, the taking in equipment to do the piston, the said pistonWith to make with the resetting spring engage which the taking in equipment is done inside the aforementioned ram, the pisteBetween the oil sac and the oil tank which are formed to n frontal side the pressure regulationMediating/helping facilities to do the valve, in addition, with pump operation in the aforementioned oil sac the hydraulic fluid givingThe sending doing, the piston therefore forced resetting ra which forced returning/repeating it makes move the rammu is provided.
