Definitions
- DTH down-the-hole
- DTH hammers have only one impulse chamber and one lifting chamber. In such cases, the piston has only one impulse area and one lifting area.
- the boost and boost areas a few DTH hammers make use of one or more chambers to move the piston, two of whose examples are presented below.
- the normal circulation hammer design described in this patent has a centrally perforated piston with a shape to provide an additional impulse chamber and an additional lifting chamber between the piston and the inner wall of the hammer outer shell. These two additional chambers are created by recesses in the outer diameter of the piston and separated by a dividing piece.
- a control bar is provided that extends from the rear head or hammer head axially downward through the central hole, the control bar having a feeding passage extending longitudinally and a discharge passage extending longitudinally. Openings in the control bar and the piston connect these passages respectively with the lifting and impulse chambers when the openings in the control bar are aligned with the openings in the piston during the alternating movement of the latter.
- the main impulse chamber is continuously connected to the source of pressurized fluid and from there the pressurized fluid is led to the longitudinal feed passage of the control bar to alternately supply the additional lifting and impulse chambers with pressurized fluid, controlled by the position relative of the piston with the control bar.
- the discharge of pressurized fluid from the main lifting chamber is controlled by the relative position between the piston and either a foot valve or an extended control bar, while the discharge of the additional lifting and impulse chambers is controlled by the relative position of the piston with the control bar.
- a disadvantage of this design is that the pressure in the main impulse chamber is on average equivalent to the feed pressure of the working fluid, which means that the work exerted by the pressurized fluid on this area of the piston is zero, so that the power of the piston is negatively affected.
- Another disadvantage is the cross-sectional area occupied by the control bar, resulting in reduced front and rear thrust surfaces.

- the supply of pressurized fluid to the space where the main impulse area is located, inside the rear piston head, is controlled by a valve component arranged in a tube that is connected to the hammer bar arrangement, said tube having openings to the space. .
- the discharge of said space is controlled by the overlapping of the internal surface of the piston with radial holes in said tube, said radial holes leading the pressurized fluid through the central channel in the piston to a bore hole of the drill.
- a foot valve is used to control the discharge of the space located at the front end of the piston.
- the supply of pressurized fluid to the space located at the front end of the piston is controlled by the relative position of the outer surface of the piston and the inner surface of the front cover.
