    • A single-stroke percussion device comprises a hollow cylindrical casing (1) and, mounted inside it, a reciprocally-movable striker (2) dividing the cavity of the casing (1) into an upper and a lower chamber (3, 4). A spring-loaded valve (5) is mounted on the side of the lower chamber and carries a working organ (6) fixed to it. An air distributor (7) provided with channels (8, 9, 10) and with a control grip (11) is mounted on the side of the upper chamber (3). The striker (2) has an axial channel (13) in which is mounted a tube (14) provided with a flange (15) on its external surface and with a blind internal partition (16). The tube (14) has an upper and a lower window (17, 18) located on both sides of the partition (16). An air distributing sleeve (19) provided with an internal groove (21) and spring-loaded on the side of the air distributor (7) is mounted on the tube (14). The air distributing sleeve (19) is capable of being moved, under the action of the striker (2), to its upper position where it closes the lower windows (18), and, under the action of the spring (20), to its lower position, limited by the flange (15), where it connects, through the internal groove (21), the upper and lower windows (17, 18).

    • A single-stroke percussion device comprises a hollow cylindrical casing (1) with an inlet and an outlet opening (2, 3). A striker (1) is mounted inside the casing (1) so as to divide its internal cavity into an upper and a lower chamber (5, 6). A working instrument (7) is mounted in the casing (1) on the same side as the lower chamber (5), mounted in the upper part of the casing (1) is a grip (9), provided with channels and with an air distributing mechanism (8). A sleeve (12) with openings (13) is mounted on the casing (1) so as to form, together with the latter, a cavity (14). An air distributing bushing (15) spring-loaded in the axial direction is mounted inside the cavity (14). The outlet openings (3) of the casing (1) are situated at the same level as the openings (13) of the sleeve (12). Radial openings and grooves (17) are provided in the air distributing bushing (15) at the same level as the radial openings (16) on both surfaces of the air distributing bushing (15). The striker (4) spring-loaded on the same side as the lower chamber (5), is provided with at least one channel (18).
    • 单冲程冲击装置包括具有入口和出口(2,3)的中空圆柱形壳体(1)。 撞击器(1)安装在壳体(1)内,以便将其内腔分成上部和下部腔室(5,6)。 工作器具(7)安装在与下室(5)相同侧的壳体(1)中,安装在壳体(1)的上部是具有通道的手柄(9) 空气分配机构(8)。 具有开口(13)的套筒(12)安装在壳体(1)上,以便与空腔(14)一起形成空腔(14)。 沿轴向弹簧加载的空气分配衬套(15)安装在空腔(14)的内部。 壳体(1)的出口(3)位于与套筒(12)的开口(13)相同的高度。 径向开口和凹槽(17)在空气分配衬套(15)中设置在与空气分配衬套(15)的两个表面上的径向开口(16)相同的水平面上。 弹簧加载在与下室(5)相同侧的撞针(4)设置有至少一个通道(18)。
