Hydraulic machine-tool avoids oil spillage and explosion risk by locating compression part of pump, master cylinder, electronically controlled hydraulic distributors and recycling valves in oil tank

摘要

A compression cutout machine tool (10) has upper and lower plates (20,24) and slave actuating cylinders (22,26). An L shaped oil tank (12) contains within the shorter limb (64) the pump compression unit driven by a motor (14) and within the longer limb (68) the master cylinder (32) and intermediate conduits (36), the oil recycling valves (34) and the hydraulic distributors
