Abstract
The utility model relates to an executive component applied in the field of pneumatic hydraulic pressure, in particular to a stable-speed air oil hydraulic cylinder. An air oil converter is added on the basis of the original air cylinder, a principle of small compressibility of oil is adopted for air and liquid use, and needed oil is infused into the air oil converter in advance. When the cylinder is used, compressed air is pressed into the air oil converter through a solenoid directional valve so as to form pressure in the air oil converter, stressed oil is pressed into one end of a right cavity of the cylinder through a third rubber tube connected with the air oil converter and the cylinder, and a cylinder piston is pushed to be retracted to the left side. Then one end of the left cavity of the cylinder is used for reversing air supply through a solenoid valve, and a piston rod extends out to force oil in the right cavity to be pressed out. The extending speed of the piston rod can be changed by adjusting a flow adjusting valve. The stable-speed air oil hydraulic cylinder operates stably, works reliably, and has a low noise and an obvious buffering effect.
