Abstract

The paper briefly outlines the state of development of impulse technology. The schemes of hydraulic machines of impulse action with percussion mechanisms of the sixth and seventh classes are presented. The calculation of impulse mechanisms with a pneumatic chamber of the working stroke is given. The physical model of the drain pipeline is presented. Shown is a diagram of the forces acting on the striker during the working stroke. The dependence of the relative energy losses on the ratios of the cross-sectional areas of the working chamber and the drain pipeline is presented. Recommendations are given for the use of a pneumatic accumulator in the drain branch of the pipeline of a pulsed hydraulic mechanism with a pneumatic chamber of the working stroke
