    Abstract: A silencer cover adapts to a heat expansion of a silencer even when, for example, the silencer cover has a large size and is attached to the silencer over an area from the front to the rear. A silencer cover is provided for a silencer connected to a downstream end of an exhaust pipe of an engine. The silencer cover is fixed to a fixing support provided to the silencer. The silencer is heat-expanded with the fixing support part fixed as a base. The fixing support part is provided at a front end portion, in a vehicle front-rear direction, of the silencer. With a tail pipe constituting a rear end portion of the silencer, the rear end portion of the silencer is provided with a slide structure in which the silencer cover is slidably supported.

    Abstract: A silencer for a firearm which incorporates a cylindrical housing, front end cap, mean of attachment to the muzzle of a firearm, spacers and an improved cone baffle design. The proposed device incorporates a novel cone baffle design which uses concave flutes to increase surface area and thereby sound reduction. The geometry of this new cone baffle minimizes the weight of a silencer, maximizes internal volume, and effectively reduces sound and flash which are the result of a discharging firearm.
