Перфоратор относится к оборудованию для горной промышленности и может быть использован при бурении шпуров и скважин. Для повышения ударной мощности и износостойкости перфоратора лабиринтные канавки поршня выполнены в виде профиля, донная часть которого образована дугой окружности, переходящей в наклонную под острым углом к оси поршня переднюю часть профиля, а задняя часть профиля представляет собой прямую, перпендикулярную к оси поршня. Глубина канавки равна диаметру дуги окружности донной части профиля. Диаметр дуги окружности донной части профиля канавок и расстояние от кромки поршня до первой канавки и между канавками выбирают оптимальным, зависящим от величины зазора между поршнем и цилиндром.The perforator relates to equipment for the mining industry and can be used when drilling holes and wells. To increase the percussion power and wear resistance of the perforator, the labyrinth piston grooves are made in the form of a profile, the bottom of which is formed by an arc of a circle turning into the front of the profile inclined at an acute angle to the axis of the piston, and the rear part of the profile is a straight line perpendicular to the piston axis. The depth of the groove is equal to the diameter of the arc of the circumference of the bottom part of the profile. The diameter of the arc of the circumference of the bottom part of the profile of the grooves and the distance from the edge of the piston to the first groove and between the grooves is chosen optimal, depending on the size of the gap between the piston and the cylinder.
