    A pneumatic reciprocating mechanism comprising a working member (11) reciprocably powered in a housing (10) and forming together with a vibration absorbing reaction support member (12) and an elastic seal element (47) a working chamber (49) which is supplied with pressure via an air feed valve (54.55). The latter is positively coupled to the working member (11) and controls the air flow through openings (54) in the reaction support member (12) in response to the relative positions of the working member (11) and the reaction support member (12) The elastic seal element (47) is associated with the working member (11) and has an annular valve collar, which is arranged to establish sealing contact with a diverging peripheral wall of the reaction support member (12) by radial expansion due to the air pressure in the working member (49).

    1 The invention relates to mining and construction machinery of percussion. A pneumatic hammer, containing a housing, located in the housing, and a working tool, is known. A disadvantage of the hammer is the increased consumption of compressed air. The closest to the invention. The technical essence and achievable result is a pneumatic hammer with a central compressed air supply channel containing a working tool axially spring-loaded working tool mounted along the tool axis and forming a pneumatic chamber sealing element working tool, and the glass, the cavity of which communicates with the compressed air supply channel /.J. A disadvantage of the known hammer is the complexity of its design. The purpose of the invention is to simplify the design of the hammer. This goal is achieved by the fact that in a pneumatic hammer with a central channel of compressed air supply there is a working tool placed axially spring-loaded working tool mounted along the tool axis and forming a sealing chamber fixed to the end of the working tool and a glass cavity. Kotorog communicated with the channel of compressed air, the sealing element is ejected in the form of an elastic annular cuff with a skirt, periodically entering into tight engagement with the inner walls which glass under pressure. in the pneumatic chamber, and inside //

    Fmgg 7 the diameter of the glass is larger than the outer diameter of the cuff skirt. FIG. 1 shows a pneumatic hammer, a general view; in fig. 24 - pneumatic chamber in different phases of the operation of the machine. The pneumatic hammer comprises a housing 1, a working tool 2 housed therein, spring-loaded with a spring 3 in the axial direction, a central channel 4 for supplying compressed air, a pneumatic chamber formed by a sealing element in the form of an elastic annular cuff 5 fixed to the working tool 2, and a glass 6 installed in the housing 1. The cuff 5 is provided with an elastic skirt 7, and on the inner surface of the larger glass 6 there is an annular groove 8. At the bottom of the cuff 5, the rod 9 is fixed with a valve 10 that overlaps the windows 11. Pneumatic sky hammer works as follows. In the initial position, the skirt 7 of the cuff 5 is engaged with the groove 8 of the cup 6. In this case, the windows 11 are open. When compressed air is supplied to the housing 1, the latter through the windows 11 enters the pneumatic chamber, an overpressure of the compressed air in the chamber is created, the air pressure breaks the engagement of the skirt 7 with the groove 8 of the cup 6, the working tool 2 makes a working stroke. The valve 10 overlaps the windows 11. Under the action of the spring 3, the tool 2 returns to its original position, in which the sealing element and the glass 6 form a pneumatic chamber. The invention allows to reduce the consumption of compressed air in air hammers and simplify their design.
