As long as the connector 8 on the accumulator is connected to the brake oil pump of the brake, it can work. After the car has braked several times, the oil pressure in the brake oil pump is lowered into the accumulator, and the oil continuously enters and pushes the diaphragm 4 to lengthen the bellows and compress the nitrogen in it. When the nitrogen pressure increases to a certain level When the pressure is greater than the oil pressure, it pushes the diaphragm 4 from the opposite direction to compress the bellows to pressurize the oil. Finally, the pressure oil is flushed out of the accumulator from the joint 8 to increase the oil pressure and then supply the brake. Work continuously. Industrial applicability

It can be used at temperatures ranging from -60 ° C to 280 ° C. It can withstand 450 ° C high temperature and -200 ° C low temperature. It can be used more than a million times. The acid, alkali and salt spray resistance are greatly improved, and it can work for more than 1000 hours under the strong salt spray. Due to the large elasticity of the corrugated tube, the vibration absorption performance and impact resistance are good, the noise is small, and the service life can be doubled. The welding of the metal casing and the separator is not restricted. Conventional thermal welding can be used, so the process is simple and the manufacturing cost low.
