摘要： A drill hammer includes an air distribution chamber in a rear end of a piston and a bore that extends to a front end. A chamber divider extends from a back-head to slidably engage inside the distribution chamber and a control tube slidably engages inside the bore. An air supply passage is provided between the control tube and the chamber divider. An exhaust port from the drive chamber extends through the chamber divider to an inside of the control tube. A distribution port to alternately supply a drive chamber and return chamber extends through the piston from the distribution chamber.

摘要： The invention relates to a pneumatic impact mechanism of the kind used in a rock drill. A reciprocating piston (4, 44) is configured: to place a drive chamber (5, 41) in fluid communication with an inlet (23; 51) towards an end of a return stroke and to place the return chamber (6; 42) in fluid communication with at least one exhaust outlet (34; 35; 52) for the piston (4; 44) to commence a drive stroke; and, to place the return chamber (6; 42) in fluid communication with the inlet (23; 51) towards an end of the drive stroke and to place the drive chamber (5; 41) in fluid communication with the at least one exhaust outlet (34; 35; 52) for the piston (4; 44) to commence a return stroke. The switching of the flow paths based on the relative position of the piston (4; 44) serves to alternately generate drive and return strokes. In one embodiment, the piston (4) has a longitudinal air distribution pocket (24) located over the inlet that communicates with the drive chamber (5) and return chamber (6) respectively through the first bridging port (32) and a second bridging port (33) in the wall of the housing, with the piston (4) respectively uncovering a first exhaust outlet (34) from the drive chamber (5) and a second exhaust outlet (35) from the return chamber (6). In another embodiment, a first radial port (45) in the piston (44) feeds a first bypass passage (46) along the length of the piston (44) which opens to the drive chamber (41) and a second radial port (48) feeds a second bypass passage (48) which opens to the return chamber (42). The radial ports (45, 48) are alternately placed in communication with the inlet (51) and a single exhaust outlet (52), located between the inlet and return chamber, is either placed in communication with the first radial port (45) or uncovered by the return stroke of the piston (44) to vent the return chamber (42).

摘要： The invention provides a control rod for a drill hammer comprising a flow passage extending from an inlet at a back head end to an outlet adjacent an opposite, inner end which is slidably locatable inside a bore of a piston and having a check valve located at the outlet. The check valve may be provided as a closure having an enlarged head in sliding sealed engagement with the flow passage. The head has a stem extending to an inner end of the control rod. A compression spring is located around the stem. On the opposite side of the enlarged head is a working face upon which pressurised air acts to compress the spring and thus open the check valve. The free end of the stem may either abut against a plug in the rod inner end or pass through an opening in the end wall and abut on the opposite side of the end wall with a stop formed on the free end of the stem. The check valve opens when the spring is compressed. In this condition the enlarged head exposes radial ports in the control rod side walls for the passage of air.

摘要： The invention relates to a pneumatic drill hammer (101) that includes a hollow control rod (119) supported from a dividing wall (123) of a back-head which withdraws from a piston bore (191) at the first end to exhaust a drive chamber (169). The dividing wall (123) is arranged between a rearwardly disposed, internally screw-threaded socket (115) and a forwardly disposed, integral air distribution skirt (111) that extends into a wear sleeve (109). A back- head connector (137) with an axial inlet (142) and a hollow, externally screw- threaded spigot (125) engages into the socket (139). A check valve closure (125) is provided at one end of a stem that is slidably supported inside the control rod (119) with a spring bias (133) against a valve seat (143) provided by the back-head connector (137).

摘要： The invention relates to a down-the-hole drill hammer. A reciprocating piston (2) has a piston head (3) with a piston stem (4) that is withdrawn from a piston stem bush (16) to exhaust a return chamber (18). A control rod (14) is supported from a back-head (15) which withdraws from an axial bore (7) in the piston to exhaust a drive chamber (17). A first lateral shoulder (10) is provided on the piston head (3) adjacent a drive stroke working area (5) and a second lateral shoulder (11) adjacent a return stroke working area (8). The first shoulder and second shoulder are of substantially the same diameter with a longitudinal air distribution passage (12) provided on the piston head (3) between the first shoulder (10) and second shoulder (11). The distribution passage is configured to provide substantially balanced, opposed working areas for pressurized working fluid within the distribution passage. The piston head is slidably engaged and reciprocates within a constant diameter bore (52) of the drill hammer provided between a lifting port (25) to the return chamber (18) and a delivery port (27) to the drive chamber, (17) with the distribution passage located over a supply port (20) provided there between. The constant diameter bore (52) is provided by a longitudinally flat portion (24) of a wear sleeve (22) and a longitudinally flat region (26) of a cylindrical skirt (21) that extends from a back-head (15).
