The former is the process of inhalation and discharged at the same pump cylinder alternately conducted by the inhalation valve and exhaust valve control;
前者的吸入和排出过程在同一泵缸内交替进行,并由吸入阀和排出阀加以控制;
Working principle: piston moves from left to right, form a negative pressure pump cylinder, the liquid tank into the pump by the inhalation valve cylinder.
工作原理:活塞自左向右移动时,泵缸内形成负压,则贮槽内液体经吸入阀进入泵缸内。
