Abstract
The utility model relates to a fluid pressure actuator, in particular to a high pressure hydraulic cylinder. The utility model relating to a high pressure hydraulic cylinder is provided with an oiling port on the backend shield, an oil spilling port is arranged on the top of cavity P, the cavity Q which is positioned at the cylinder barrel is formed between the cylinder piston and frontend shield, the inner cavity Q and cavity N are entirely separated which are separately driven by compressed air instead of compressed spring; as a result the push power of cylinder piston rod is decided by the area of cavity N and pressure, and is unable to weaken; which is good for changing stroke length according to the requirements and saving energy. The utility model could suit different working environment which improves the practicability, and has advantages of convenient operating, good effects of pressurization and certain recommendation value.
Description
