Abstract

A recoil impeller engine, comprising an energy supply deice (1), an operation sealing mechanism (2), an impeller (3), a fixed operation machine shaft frame (4) and a rotating wheel (5). Energy is ejected through the energy supply device (1), the operation sealing mechanism (2), the impeller (3) and nozzles (6) at an angle (8) along the centrifugal tangent line of the impeller. The cross-section area of the energy supply device (1) is greater than the sum of the cross-section areas of multiple nozzles (6). A nozzle pipe (7) is of a tapered shape. The water, steam and gas energy of the recoil impeller engine is converted into the injection kinetic energy of the nozzles (6) muu/2, the momentum is equal to the injection mass multiplied by the injection speed mu, and the injection power is equal to the injection force multiplied by the injection speed Fu. The recoil force of the nozzles (6) is equal to impact force −F=F, the impact force equaling to the pressure. The maximum recoil power of the nozzles (6) is equal to the injection power −Fu=Fu. The ratio between the maximum recoil power and the injection power of the nozzles (6) is 100%. The recoil impeller engine has high energy conversion efficiency.
