Abstract
Systems and methods are disclosed for a fluid-based projectile launcher having a housing, that may also include a barrel portion, and a propellant fluid chamber. Disclosed embodiments also include a valve assembly that controls flow of propellant fluid from the propellant fluid chamber to the barrel portion through a fluid passageway, and an adjustable block assembly that controls motion and/or position of the valve assembly.
Claims17
A valve assembly for a fluid-based projectile launcher comprising:
- a housing comprising a propellant fluid chamber;
- a valve assembly that selectively meters the flow of propellant fluid from the propellant fluid chamber to a fluid passageway, the valve assembly comprising:
- a valve stem comprising a valve head at a first end and located outside the propellant fluid chamber;
- and
- a valve stopper at a second end opposite to the first end and that seals the fluid passageway when closed;
- and
- an adjustable block assembly that contacts at least a portion of the valve head to limit the motion of the valve assembly.
A method of making a valve assembly for a fluid-based projectile launcher, the method comprising:
- providing a housing comprising a propellant fluid chamber;
- providing a valve assembly that selectively meters the flow of propellant fluid from the propellant fluid chamber through a fluid passageway, the valve assembly comprising:
- a valve stem comprising a valve head at a first end and located outside the propellant fluid chamber;
- and
- a valve stopper at a second end opposite to the first end and that seals the fluid passageway when closed;
- and
- providing an adjustable block assembly that contacts at least a portion of the valve head to limit the controls motion of the valve assembly.
A valve assembly for projectile launcher system comprising:
- a housing comprising a propellant fluid chamber;
- a valve assembly that selectively changes a cross-sectional area of a fluid passageway to change the flow of propellant fluid from the propellant fluid chamber through the fluid passageway, the valve assembly comprising:
- a valve stem comprising a valve head at a first end and located outside the propellant fluid chamber;
- and
- a valve stopper at a second end opposite to the first end and that seals the fluid passageway when closed;
- and
- an adjustable block assembly that controls the position of the valve assembly.
