摘　　要：介绍了一种新型的杠杆-铰杆二级増力手动液压泵的工作原理,给出了排量及输出压力的计算公式。该新型泵能在空行程阶段提供低压大流量液体,在工作行程阶段提供高压小流量液体,与传统手动液压泵相比较,工作效率明显提高。The working principle of a new type of hand pump with two-step force amplifier using lever-toggle was introduced, the calculating formulae of the displacement and output pressure were given. The new pump can provide high-flow liquid with low-pressure in vacant path stage, and can provide small-flow liquid with high-pressure in working stroke stage. Compared with traditional hand pump, work efficiency is improved significantly.
