The membrane type air-oil combining booster pump has membrane type air chamber and oil cylinder with oil cylinder piston, sealing ring to prevent oil leakage, U-shaped leather cup fixed with pin and oil exhaust valve and oil return valve in the oil exhaust port. When the compressed air entering the air chamber drives the membrane to displace, the push rod assembly drives the piston to increase the oil pressure inside the oil cylinder and the pressure in the oil exhaust port is further enlarged. When the air chamber releases compressed air, the membrane is restored gradually, the piston under the action of spring is repositioned gradually, the high pressure oil back flows to the oil cylinder via the oil return valve, the boosting course is released and relevant parts returns to original state to complete one stroke.
Description
Technical field [0001] The invention generates oil pressure through air pressure, and further increases the output oil pressure to a greater extent through the process of air-oil conversion. It is especially suitable for working occasions that require relatively high oil pressure, and is mainly used in automobiles and engineering machinery. , and various devices and equipment that require gas-oil conversion. Background technique [0002] At present, the known booster pump is composed of a piston air chamber and an oil cylinder. The main problems are: the volume is large and heavy, the maintenance is complicated and easily damaged, the cost is high and the structure is complicated. In the process of use, there are often hysteresis of piston force, piston return hysteresis, oil leakage, work failure and short working life. Contents of the invention [0003] In order to overcome the problems of piston boosting hysteresis, piston return hysteresis, oil leakage, frequent work...
