Abstract

The invention discloses a gas pressurized device which comprises a pressurized cylinder. A floating piston is arranged in a cylinder barrel of the pressurized cylinder to divide the pressurized cylinder into a pressurized chamber and an oil chamber, an inlet valve is arranged at the gas inlet of the pressurized chamber, a one way valve is arranged at the gas outlet of the pressurized chamber, theoil chamber is communicated with an oil tank through an oil pipe, and a hydraulic oil pump is arranged on the oil pipe. The gas pressurized device can directly compress low pressure gas and even atmospheric pressure gas into high pressure gas, can output gas with different high pressures according to the needs, and has high output pressure as well as the advantages of high efficiency, high outputpressure, small volume, low manufacture cost, and the like.

Description

technical field

[0001] The invention relates to a pressurizing device for pressurizing low-pressure gas to meet the requirements of high-pressure gas, belonging to the field of pneumatic and air control engineering, and applicable to the air supply system of vehicle air suspension and other similar systems. Background technique

[0002] To pressurize the gas pressure from a lower value to 20MPA or even higher pressure, a single-stage or multi-stage gas compressor can be used. For example, Chinese Patent No. "200810008837.5" discloses a multi-stage compressor, in which a low-stage compression mechanism and a high-stage compression mechanism are provided in the casing, and the intermediate-pressure refrigerant gas compressed by the low-stage compression mechanism is sucked into the compressor. The high-stage side compression mechanism performs two-stage compression, and an injection circuit is provided to inject intermediate-pressure refrigerant extracted from the refrigerant ...
