Description

При нажатии на руко тк} 2 последн  , перемеща сь по стакану б, включает пусковое устройстйо 8, которое открывает доступ сжатому воздуху от его источника (пе показан) к воздухораспределнтелыю.ау устройству 7. От воздухораспределнте«1Ы10го устройства 7 сжатый воздух попеременно подаетс  под п пад ударппкол 5 П прпиодпт его в возпратпопоступатсльпое динжеиие, в результате которого оп напоепт удары по рабочему ипструменту . Указанные дзижепи  ударпика 5 вызывают колебательные движени  корпуса 1 и руко тки 2, которые из-за палпчи  пружипы 3 сдвинуты по фазе.When pressing the handle} 2 last, moving around the glass b, turns on the starting device 8, which gives access to compressed air from its source (not shown) to the air distribution device and device 7. From the air distribution device 1X10 of the device 7, the compressed air is alternately supplied p pad shockpkol 5 P priododpt him in return for a small dignity, as a result of which opapoppt blows to the working tool. These jazz strikes 5 cause oscillatory movements of the body 1 and the handle 2, which, due to the palpchi, the spring 3 are out of phase.

Отработанный сжатый воздух через отверстп  10 п 11 выходит в ат.мосферу. При движени  по расточке 12 в струю воздуха через каналы 13 засасываетс  атмосферный воздух. Колебапп  корпуса 1 и руко тки 2 вызывают П)льсацпи в струе отработанного воздуха выход агего из отверстпй 11, и в струе воздуха , подсасываемого через каналы 13.The exhaust compressed air through the holes 10 p 11 goes into the atmosphere. When moving along the bore 12, atmospheric air is sucked into the stream of air through the channels 13. The slide block of the housing 1 and the handle 2 cause the pulsation in the jet of exhaust air to exit from the holes 11, and in the jet of air sucked through the channels 13.

зе. Указаппое обсто тельство способствует лучшему смешиванию в расточке 12 и вызывает большие потери энергии. Это, в конечном реззльтате, ведет к снижению скорости истечени  отработанного воздуха в атмосферу , т. е. аэродинамического шума.see This circumstance promotes better mixing in the bore 12 and causes large energy losses. This, in the final result, leads to a decrease in the flow rate of exhaust air into the atmosphere, i.e., aerodynamic noise.

Паправлепие отработанного воздуха вниз преп тствует подъему образующейс  в пропессе работы пыли, что оздоровл ет услови  труда.The right direction of exhaust air prevents the rise of dust generated in the work process, which improves working conditions.

Предмет изобретени Subject invention

Пневматический бетонолом, включаюш;ий подвижную руко тку, корпус с размещенным в нем ударником и выхлопными отверсти ми, на выходах которых установлен эжектор, отличающийс  тем, что, е целью снижени  шума и улучшени  условий эксплуатации, эжектор образован корпусом и руко ткой, имеющей каналы, соединенные с выполненной на впутреппей поверхности руко тки расточкой, состо щей по длине из частей разного диаметра .A pneumatic breaker, including a movable handle, a housing with a hammer placed in it and exhaust openings at the outlets of which an ejector is installed, characterized in that, in order to reduce noise and improve operating conditions, the ejector is formed by a housing and a handle having channels , connected with a handle made on the surface of the handle with a boring consisting of parts of different diameters in length.
