One shell has inlet and outlet ports divided by a wall with which the membrane co-operates under the influence of pressure within the other shell.  The later is connected to the inlet port by a permanently open passage and to the outlet port by a controlled passage.  The wall has a rib against which the membrane rests in the closed position, and the profiles of this rib ensure an efficient seal.  The outer shell with the control cavity can be asymetrically shaped.

Abstract: TITLE OF THE INVENTION                     DOWN-THE-HOLE HAMMER                  ABSTRACT OF THE DISCLOSURE      A down-the-hole hammer of the type adapted for receiving a bit at the lower end and for being connected to the lower end of a drill string through which compressed air is supplied to the hammer.  The supply of air to the hammer when the bit at the lower end is resting on the bottom of the hole causes a piston in the hammer to reciprocate and to beat upon the upper end of the bit so that the material at the bottom of a hole is reduced.  The piston, by reciprocating in the hammer, accomplishes the valving of the fluid which causes the piston to reciprocate, and when the hammer is lifted from the bottom of the hole and the bit moves downwardly, the piston ceases reciprocation while air blows off through the bit to the bottom thereof to clear debris from the hole being drilled.
