摘要： In a rock drill, the feed force is transmitted from the housing 11 of the rock drill to the drill stem or drill stem adapter 14 via a damping piston 17. The damping piston 17 rebounces by the reflected compressive shock waves and the rebounce is sensed and used to control a control pin 48 which adjusts the stroke length of the hammer piston 13 so that the reflected shock wave energy is minimized.

摘要： In a striking device the striking mechanism (1) is provided with a means (32) intended for its elastic resilient connection with the working machine and rigidly secured on a casing (3) of the striking mechanism (1) in a plane which is perpendicular to its longitudinal axis and passes through the stroke center (0). The first chamber (21) of a valve distribution mechanism (2) is connected to the discharge line (25) through an annular groove (23). Said annular groove (23) is made on the internal surface of the casing (3) of the striking mechanism (1), which forms an overflow chamber (13), and is located farther along the axis from the first chamber (4) than a channel (28) which is provided in said casing (3) to connect the overflow chamber (13) to the second chamber (22) of the valve distribution mechanism (2), whose inlet channel (30) contains a unidirectional restrictor valve (31). The working instrument (11) at 'idle strokes' interacts with the casing (3) of the striking mechanism (1) through a hydraulic shock absorber (46).

摘要： The present invention relates to hydraulic percussion mechanisms used in mining and construction industries for treating frozen soils and rocks. This mechanism comprises a body (1) with a gas energy accumulator (2), an introduction chamber (3) containing a striker (4) with a head (5), and a stepped valve (6) biased by said resilient energy accumulator (2). The outer surface of the valve (6) and the inner surface of the body (1) define an overflow chamber (7) that is periodically connected with the introduction chamber (3). Grooves (9) are formed in the inner surface of the body (1) and in the outer surface of the overflow chamber (7), wherein the surface of said grooves (9) together with the stepped valve (6) define a gap in the form of a labyrinth (10). The stepped valve (6) is mounted so as to co-operate with the body (1) and to shut the labyrinth, thus defining a pressure chamber (8). The inner surface of the stepped valve (6) and the head of the striker (4) define a sub-valve chamber (11) which is connected with the pressure chamber (8) when the striker enters the valve through channels (12). The overflow chamber (7) is in continuous communication with a drainage duct (13) while the introduction chamber (3) is in continuous communication with a pressure duct (14).
