Description

1. Technical field:

[0001] The invention relates to an automobile brake pump, in particular to a three-inlet and multi-outlet type two-stage electromagnetic booster brake master cylinder. 2. Background technology:

[0002] With the rapid development of the economy, more and more people and goods are appearing in various parts of our country. As one of the important means of transportation and transportation, automobiles are becoming more and more popular in families and businesses.
