摘要

System and equipment for pressurization hydraulic, semi trailer vehicle, and adaptation of the cylinder of the vertical type and horizontal type for use in the semi - trailer vehicle for transportation of CNG.The present invention relates to an equipment and / or pressurization station also known as "HPU hydraulic (hydraulic pressurization unit), which may be connected to a semi-trailer with SRV of the type known as cart of vertical rollers and / or a cart of cylinders ho. Rizontais (drum).The present invention also refers to a system of pressurization and control of CNG (compressed natural gas) of a semi-trailer vehicle to the supply line for vehicular natural gas (CNG) maintaining a constant pressure throughout the operation. The system allows also claimed But carry CNG in high pressure safety and low operating cost.
