Abstract:
The present invention provides a smoke screen generator with a high diffusion rate of a smoke screen. Ends at both sides of a cylindrical housing are closed by a first closure  20  and a second closure  30  respectively, and a flow path changing member  60  is attached at an interval in an axial direction from the second closure  30.  At the time of actuation, a smoke screen source passes through a smoke screen source discharge port  38,  first discharge flow paths  44, 45  and  46,  and a second discharge flow path  47  and is discharged from a final discharge port  48.  Since the smoke screen source is radially discharged from the final discharge port  48,  a diffusion rate of a smoke screen increases.

Claim (Index 1):
A smoke screen generator comprising a cylindrical housing, an igniter and a smoke screen generating agent which are accommodated in the cylindrical housing,\n a first closure including the igniter and closing a first end opening of the cylindrical housing, a second closure having a first discharge flow path and a first discharge port, which is an outlet of the first discharge flow path, and closing a second end opening of the cylindrical housing on an opposite side in an axial direction to the first end opening, a flow path changing member for a smoke screen source being attached to an outer side of the second closure, a second discharge flow path being provided between the second closure and the flow path changing member and in communication with the outlet of the first discharge flow path, and an outlet of the second discharge flow path being a final discharge port, the first discharge flow path being extended in a direction coaxial with the cylindrical housing and the second discharge flow path being extended in a different direction from that of the first discharge flow path, the first closure having a discharge hole for discharging an ignition product which is generated at the time of actuation of the igniter, a porous cylindrical body being arranged between a surface of the first closure where the discharge hole for the ignition product is not provided and the first discharge flow path of the second closure, a space between an inner circumferential wall surface of the cylindrical housing and the porous cylindrical body being a smoke screen generating agent-accommodating chamber which accommodates the smoke screen generating agent, and the discharge hole for the ignition product facing the smoke screen generating agent-accommodating chamber, and at the time of actuation of the igniter, the smoke screen generating agent in the smoke screen generating agent-accommodating chamber being ignited and burned to generate a smoke screen source, the smoke screen source moving through an inside of the porous cylindrical body, passing through the first discharge flow path, the first discharge port and the second discharge flow path, and thereafter being discharged from the final discharge port to the outside in order to generate a smoke screen.
