控制进油阻力的变量柱塞泵设计

The Design of a Variable Displacement Pump to Control Entering Oil Resistance

以阀式径向柱塞定量泵为基泵设计了控制进油阻力的变量机构。该机构采用了活动滑塞来补偿柱塞腔吸油量的不足，因而防止了吸油气穴的产生。

This article designed a displacement setting mechanism by the fixed quantity of valve model radial column piston as base pump. The adoption of moving piston compensated the insufficent quantity of the drawing oil cavity and prevented to bring about air cavitation.
