A muffler for use with pneumatically powered apparatus has a cylindrical housing with air outlet slots, to the back of which there is a pipe-like damper cartridge. Within the cartridge there is an axially adjustable choke body whose choke head is guided with a sliding fit by radial nosepieces resting against a support sleeve for the damper cartridge. A coned air flow controlling part of the choke head is used together with a coned face of the inner end of a connection inlet hole of the housing for forming an adjustable choke gap. |
