Abstract
An air path and improved safety valve combination for toy air guns including a housing in the shape of a gun, multiple barrels mounted to the housing, a piston, cylinder and spring combination for generating blasts of compressed air mounted to the housing, an air passageway structure with an air path channel mounted in the housing, and multiple valve elements movable in the air path channel between open rearward positions and closed forward positions. When in the rearward position, each valve element directs a blast of compressed air to an associated barrel because the barrel is loaded with a soft foam dart of proper shape. When the valve element is in a forward position indicating an empty barrel, the valve element causes the blasts of compressed air to cascade to the next valve element of a dart-loaded barrel in sequence and in a very efficient manner.
