摘要

The fluid chambers and orifices in the control unit of variable-displacement pump will make great influences on the control performance of variable-displacement pump. Some works (Huang et al., 1988; Li et al, 2001; Wu et al, 1992) have been done on the optimum design of the orifices. However, the influences of fluid chambers were neglected in these research efforts. It is well know that the volume of fluid chambers should be as small as possible so that its influences could be neglected. In order to quantify the condition, the mathematic model of the load sensing control unit of variable-displacement pump is established and represented as a form of system block diagram. Based on it, the design problems of the fluid chambers and damping orifices are discussed. A few of simple and practical design formulas are put forward, which are valuable to the design of load-sensing variable-displacement pump.
