The passage can include an entry region, a projectile acceleration pathway, and an exit region for a moving projectile having a magnetically susceptible portion. The magnetic components can be arranged around the projectile acceleration pathway such that the moving projectile travels through the magnetic components. The control system can be coupled to the magnetic components and can be configured to actuate the \magnetic components at one or more proper times to facilitate one or more applications of magnetic force from the magnetic components to the moving projectile as the moving projectile passes through the projectile acceleration pathway in a manner that accelerates the moving projectile.

US12504254 - Shell-throwing toy long gun

A shell-throwing toy long gun includes a valve assembly that controls whether the high-pressure gas output from an air supply unit can flow to a gun mechanism. The valve assembly includes a valve stem, an air outlet, a sealing rings and collars fitted on the outer side of the valve stem, a sleeve, and a spring. The valve stem can be moved by the impact of a hammer from a striking unit. One end of the air outlet is provided with a first connecting tube, and one end of the sleeve is provided with a second connecting tube. The first connecting tube and the second connecting tube are correspondingly connected to cover the air passage within the valve stem, preventing the leakage of high-pressure air. The air supply unit includes a cylinder connector, which can be connected to a gas cylinder and is disposed inside the grip.
