Abstract

The utility model discloses a novel oil-gas separation type automatic oil filling gas exhausting pressure cylinder. The novel oil-gas separation type automatic oil filling gas exhausting pressure cylinder comprises an oil storage barrel, a pneumatic cylinder and a pressure cylinder body. The pneumatic cylinder is connected with the pressure cylinder body through an intermediate body, a pressure oil duct is arranged above the oil storage barrel, an oil returning spring is arranged inside the oil storage barrel, and an oil passage is arranged between the intermediate body and an oil barrel middle cover. The hydraulic oil inside a pressure oil space is pressed to the pressure cylinder body through the oil passage under the action of a pressure oil piston, automatic oil filling is achieved through the pressure oil duct, and a front piston is pushed to drive a front rod to strike external articles. The pressure cylinder body further squeezes the hydraulic oil inside the pneumatic cylinder, and the produced high-pressure hydraulic oil acts on the front rod to produce high-pressure output force. Due to the fact that the oil returning spring is arranged inside the pressure oil space of the oil storage barrel, the oil returning spring drives the pressure piston to do reciprocating motion to make contact with an oil barrel lower cover, accordingly, larger driving force is produced, and the output force of the hydraulic oil inside the pressure oil space is effectively enhanced.
