FIELD: construction.
SUBSTANCE: impact device comprises a housing, a striker located in the housing and dividing it into chambers of working stroke and idle run, an air distribution mechanism comprising a cover, a pre-valve cavity, valves, command chambers connected with command channels to the chambers of working stroke and idle run, intake channels and an exhaust port. A sub-valve bushing is located in the cover. In the annular cavity between the sub-valve bushing and the cover there is a separating bushing with guide axial grooves for valves and valves made in the form of annular sectors with the possibility of independent axial movement. Flanges arranged in the pre-valve cavity are made on the lower end of the valves. The valves form with their upper end form in the annular cavity command chambers connected with command channels to the chambers of working stroke and ide run.
