Description

The invention relates to mechanical engineering and is based on the use of manual pneumatic machines.

: The aim of the invention is to increase the impact energy.

The goal is achieved by the fact that a pneemaic impact memory card with a nabj. BiaJ i6oftj on the casing is complete, | HST.

 The drawing shows a pneumatic impact impact, longitudinal section.,

I The pneumatic impact drum machine contains a coaxial usty-: (-: enveloped casing. 1 with exhaust channels — lag-2 and casing 3 with vtusch windows 4 and 5. with a protrusion 6 of smaller diameter and a longitudinal groove 7 6 with the possibility of limited displacement; 1g; up to the stop; 8 a washer is installed; 9, I cross channels 10, I inform you of the preceding comprehending window with windows 5, impact f1y piston 12 with air distributor - TJejibHbM device 13 and a working ifcmes-sTOM 14 knc

blunt to the air distribution device 13 and brings the body 3 and the shock piston 12 into reciprocating movements, as a result of which the latter produces useful blows with its working tool 14.

When the movement of the piston 12 down. he opens the windows 5j with his upper end and the compressed air is exhausted, through the channels 10 he begins to move towards the chamber 11. Under the action of pressure from below, the washer 9 is moved to its upper position.

Through the opened channels 10, the squeezed air enters the chamber t1 and continues its way through the constantly open groove towards the exhaust channels 2.

After the windows 4 are opened by the piston 12, the exhaust of the exhaust air begins: the pressure in the chamber above the upper end of the piston 12 of the housing 3 and in the channels 10 becomes less pressure in measure 11, Next, the washer 9 moves down and closes the channels 10, however, having isolated chamber 11 from them. The air cut off in chamber 11 can only be released into the atmosphere through slot 7.

This invention will make it possible to increase the impact energy due to the elimination of the outflow of spent expander from the expansion chamber of the expansion chamber back into the inner canopy of the housing.
