ROTARY GEAR PUMP MECHANISM

Abstract

Impellers 1 and 2 rotate about fixed axes A and B. Impeller 1 has two teeth d and impeller 2 has two recesses c whose profiles are made up of portions of cycle curves. When impellers 1 and 2 rotate, fluid is continuously delivered in the direction of arrows a and b. The suction and discharge chambers are separated by imparting special profiles to teeth d and recesses c of the impellers. The impellers are driven by two meshing identical gears keyed to the shafts of impellers 1 and 2. $4003$THP,GP$
