Abstract:
A piston includes a crown portion generally defining an axis and having a skirt connecting portion. The skirt connecting portion is defined, at least in part, by a first crown mating portion, a second crown mating portion positioned radially from the first crown mating portion, and a crown chamber surface extending between the first crown mating portion and the second crown mating portion. The piston also includes a skirt having a crown connecting portion. The crown connecting portion is defined, at least in part, by a first skirt mating portion, a second skirt mating portion, and a skirt chamber surface extending between the first skirt mating portion and the second skirt mating portion. The first crown mating portion is selectively coupled to the first skirt mating portion. The second crown mating portion is selectively coupled to the second skirt mating portion to define a piston chamber that is defined, at least in part, by the crown chamber surface and the skirt chamber surface.
Coupler For Attaching A Suppressor To A Firearm Flash Hider
A coupler for attaching a suppressor to a firearm flash hider. The coupler includes a main body, an inner collar, and an outer collar. The main body defines a through bore configured to closely receive the flash hider at one end and for the passage of the bullet at the other. The main body defines a first threaded portion proximate the central portion thereof, the threads being right-handed threads. The main body defines a sound suppressor attachment device at the second end thereof. The inner collar defines a through bore oriented coaxially thereto. A first end of the through bore is configured to receive the first end of the main body. Proximate the second end of the inner collar, the through bore defines a second inner diameter dimensioned to receive the firearm flash hider. The inner collar carries a plurality of locking fingers, each pivotally mounted on the inner collar via a pivot pin. When the inner collar is received over the flash hider, the fingers are pivoted toward the barrel in order to prevent axial movement of the flash hider with respect to the coupler.

Abstract:
Internal combustion diesel engines require localized cooling methods for the pistons in these engines. The lubricating oil for the engine is also used as a cooling medium. The operating temperature and stresses in the newest models of diesel engines are extremely high and approach the mechanical limits of the engine component materials. Therefore, supplemental methods are required to remove the excessive heat generated during engine operation. In order to increase the amount of heat transferred to the oil from the piston in a given time, a plurality of fins or grooves are formed on some of the heat transferring surfaces of the piston, such as inside the combustion bowl. The increased surface area of the component allows more heat to be dissipated to the oil that is in contact with the surface. The more heat removed from the piston, the more efficiently and economically the engine will perform in service.
