摘要： A choke for use with a shotgun is provided. The choke includes a body that defines a bore with a longitudinal axis. The body is configured for engagement with a shotgun so that projectiles from the shotgun can traverse therethrough and out of an end of the bore. The body has a circumference and defines at least one port for venting gas from the bore through the circumference. The port is located within a first radial arc that extends 180° about the longitudinal axis. No ports are present for venting gas from the bore through the circumference that are located within a second radial arc that does not overlap the first radial arc and that extends 180° about the longitudinal axis. An associated method is also provided.
摘要翻译：提供与霰弹枪一起使用的扼流圈。扼流器包括限定具有纵向轴线的孔的主体。身体构造成与霰弹枪接合，使得来自霰弹枪的射弹可以穿过其中并且从孔的一端流出。主体具有圆周并限定至少一个端口，用于从孔穿过圆周排出气体。端口位于围绕纵向轴线延伸180°的第一径向弧内。不存在用于从孔穿过气体排出气体的端口，所述圆周位于不与第一径向弧重叠并且围绕纵向轴线延伸180°的第二径向弧内。还提供了相关联的方法。

摘要： A choke for use with a shotgun is provided. In accordance with one embodiment the choke has a body that defines a bore with a longitudinal axis therethrough. The body is configured for engagement with a shotgun, and the bore is positioned for traversal of a wad and shot therethrough and out of an end of the bore. The body has a circumference, an inner surface, and outer surface. The body defines at least one port for venting gas from the bore that extends from the inner surface to the outer surface. The shape of the port at the inner surface is asymmetrical.
摘要翻译：提供与霰弹枪一起使用的扼流圈。根据一个实施例，扼流器具有限定具有穿过其中的纵向轴线的孔的主体。主体被构造成与霰弹枪接合，并且该孔被定位成穿过一个瓦并且穿过其穿过该孔的一端。本体具有圆周，内表面和外表面。主体限定至少一个端口，用于从内表面延伸到外表面的孔中排出气体。内表面的端口形状是不对称的。
