康明斯6BT发动机增压器回油管A3960734
本实用新型涉及一种柴油发动机增压器回油管总成，其特征在于：所述增压器回油管总成主要是金属波纹管和法兰构成；所述金属波纹管为无过渡管对接的一整体，所述金属波纹管一端插入所述法兰中间孔中后扩口翻边呈环面。该回油管总成由于采用金属波纹管，将原来的刚性结构改为柔性连接，无配合、取消了法兰与硬管焊接及中间过度段，克服了原有的刚性配合易断裂及焊点松落、密封性较差的问题，提高了可靠性，且装配方便，降低了生产成本。
Turbocharger oil pipeA3960734
The utility model involves a turbocharger for diesel engine oil pipe Assembly, characterized by: turbocharger oil pipe assemblies referred mainly metal corrugated pipe and flange form; metal bellows is mentioned no transition pipes joint of a whole, mentioned in metal bellows end into the described flange after Kong Zhong flared flange in the middle is the torus.Back at the tubing assemblies as the use of metal corrugated pipe, the rigid structure of the original to a flexible connection, no matching cancellation of flanges and tubes welded and excessive, to overcome the existing rigid tie faults and problems with poor solder pine falls, sealing, increased reliability, which are fitted, reducing production costs.
