Design of a pressure regulator for lever-operated knapsack (LOK) sprayers


Design of a pressure regulator for lever-operated knapsack (LOK) sprayers



AMA, Agricultural Mechanization in Asia, Africa and Latin America 32(4): 23-27



A pressure regulator was designed to improve accuracy in applying pesticides of commercially available lever-operated knapsack sprayers. It operates by maintaining the output pressure regardless of excessive pumping of the operator. The design features a diaphragm that deflects at varying magnitudes depending on the magnitude of pressure of the liquid where it is subjected to.
