Abstract
Under consideration is the principal diagram of a percussive tool with a ring-shape elastic valve installed in the air distribution system: the valve closes when contacting the housing and opens under action of elastic forces. The operability conditions and basic design parameters of the valve are determined. The authors characterize contact interaction between the ring-shape valve and the side slide surface when the valve is closing. The balance of forces affecting the ring-shape valve is shown.
