Synthesis Of Variable Displacement Linkages and Application to Radial Piston Pump

  Ravindra k. Ambekar,  Prof. S S. Mestry

- This paper attempts to acquire the synthesis of variable displacement linkages by overlay method using Auto-CAD software. This linkages are fabricated with design dimensions and applied to the radial piston pump. There are several types of positive displacement hydraulic pumps and motors including gear, screw, lobe and piston machines. Of these machines, there are three main architectures commonly used in variable displacement applications are axial piston, bent axis, and vane. But these pumps are very costly. This paper presents synthesis of variable displacement linkages, fabrication of linkages and application to radial piston pump to increase volumetric efficiency with minimizing the overall cost of pump. The prototype is prepared and experimental results are presented to validate the model. It will be shown that this linkage-based, variable, positive displacement pump shows promise as a highly efficient alternative to other variable displacement pumps.

Keywords- Radial piston pump, Variable displacement linkages, Overlay method, Volumetric efficiency
