US12736299 - Valve assembly for a projectile launching system
A valve assembly may include a housing assembly with an expansion chamber. The assembly may also include a bolt movably positioned in the expansion chamber with a longitudinal through hole and a radially disposed through hole. The bolt may have first, second, and third positions. In first position and third positions, the expansion chamber may be sealed from the longitudinal through hole and the radially disposed through hole. In the second position, the expansion chamber may be fluidly coupled to these holes. The assembly may include an orifice to fluidly couple the expansion chamber to a first bolt surface. The assembly may include a stem that sits within the longitudinal through hole of the bolt when the bolt is in the first position. The assembly may also include a sealing member to selectively seal or fluidly couple the expansion chamber and the orifice.
