  • the US Pat. Nos. 7,931,118 B1 describes a baffle for use in a firearm silencer which employs proximal and distal surfaces with at least one connecting wall positioned between the proximal and distal surfaces and defining two expansion chambers between the proximal and distal surfaces.
  • the connecting wall has a borehole and at least one opening in the wall itself and at least one opening from the borehole in at least one of the expansion chambers positioned between the proximal and distal sides of the baffle.

  • an angle ⁇ between 30 and 60 °, preferably 45 ° with the elongated base member 13a preferred (but not shown here).
  • a second central section 10b is shown for a muffler device 1 for a single-barreled firearm. From the elongated base member 13b protrude the Kammentrennputemente 15d, 15e and the end wall member 17 from. The corresponding bullet holes 15d, 15e or the reject opening 17a are arranged in alignment with each other (as well as with the remaining bullet holes of the first center section 10a). Between the chamber partition elements 15d and 15e of the flat portion F 5, and between the chamber dividing wall element 15e and the end wall 17 of the flat portion F 6 is formed. On the front of the chamber partition wall member 15d of a flat portion F 4 is disposed with the groove 19b, which in turn runs correspondingly over the second central portion 10b. The narrow side 14b of the elongated base member 13b is also used here for mounting in the corresponding recess 16 of the first central portion 10a.
  • recess 32 of the attachment part 30 in turn serves for receiving and mounting the narrow side 14a of the first metal piece 10a.
  • the elongated base elements 13a and 13b thus form the bottom of the muffler device for a single-barreled firearm.
  • the housing part 20 in turn closes flush with the attachment part or the flange ring 36.
  • the corresponding holes and the mounting hole for mounting the muffler device to the muzzle are not shown for reasons of simplicity.
