Abstract
A pneumatic paintball marker has, for example, a sleeve that controls the passage of air through the longitudinal barrel or opening within the marker. By sequentially filling separate chambers defined within the opening and the sleeve, the sleeve is able to translate axially through the opening in a sequential manner. When the sleeve is in a forward position, air is caused to be released through the barrel, propelling the paintball. A sear member engages the sleeve and prevents it from inadvertently moving to a forward position. Air filling the chambers returns the sleeve to the loading position.

A marker comprising:
- an outer member having an opening disposed generally axially therethrough and a gas inlet passage;
- a sliding member slidingly received within the outer member and configured to move between a first position and a second position, the sliding member being closer to a muzzle end of the marker in the first position than in the second position;
- a first chamber positioned within the outer member and configured to be in flow communication with the gas inlet passage when the sliding member is in the first position and in the second position;
- a second chamber positioned within the outer member and configured to be in flow communication with the first chamber at least when the sliding member is in the second position;
- and
- a passageway disposed between the first chamber and the second chamber, the passageway being sized with respect to the gas inlet passage so as to impede the gas entering the second chamber from entering the first chamber at least when the sliding member is moving from the first position to the second position.
A marker comprising:
- a pressurized gas source;
- an outer member having an opening disposed generally axially therethrough;
- a gas inlet passage formed in the outer member and being in flow communication with the pressurized gas source;
- a sliding member received within the opening disposed in the outer member and configured to slide between a first position and a second position that is aft of the first position, the sliding member having a first pressure surface;
- a first chamber and a second chamber positioned within the marker;
- and
- a passageway disposed between the first chamber and the second chamber;
- wherein:
- the second chamber is configured to be in flow communication with the gas inlet passage when the sliding member is in the first position and in the second position;
- the first chamber has a second pressure surface sized and configured so that the sliding member is biased towards the first position when the first chamber and the second chamber are at substantially equal pressures;
- and
- the passageway is sized so as to slow the gas entering the second chamber from entering the first chamber at least when the sliding member is moving from the first position to the second position.
A gas pressurized paintball marker comprising:
- a housing comprising an opening disposed generally axially therethrough and defining one or more interior surfaces;
- a sliding member slidably received by the one or more interior surfaces of the opening, the sliding member being slideable between at least a first and a second position;
- a frame configured to support the housing and having a handgrip portion;
- a release mechanism configured to releasably hold the sliding member in a third position, the third position being axially between the first and second positions;
- and
- a first air chamber and a second air chamber defined within the housing;
- wherein:
- the first and second chambers are pressurized at least when the sliding member is in the third position;
- and
- the sliding member moves axially away from the first position in response to the pressurized gas filling the first air chamber.
