Design and Experimental Modeling of Variable Flow Radial Piston Pump

This paper present variable displacement linkage which use for desired position displacement. Using this particular displacement run a radial piston pump for variable discharge. This variable Discharge is relation with Control angle and Pressure. In hydraulic power systems, variable displacement pumps save power, increase the productivity or control the motion of a load precisely, safely and in an economical manner .The displacement varying mechanism and power to weight ratio of variable displacement piston pump makes them most suitable for control of high power levels. Positive Displacement Pumps are "Constant Flow Machines" Thus objective of research is defined to develop a variable displacement linkage that will enable to vary the stroke of an two cylinder radial piston pump, thereby offering to vary the discharge of the pump using manual control. Also find relation of Discharge, Control angle and pressure.
