Methods and apparatus for a direct connect on-off controller

An on-off controller for controlling a flow of fluid from a provided bottle, wherein the bottle has a poppet valve biased in a closed position, wherein fluid flows from the bottle when the poppet valve is open, the on-off controller comprising:

• a body having an axis, a cavity, an inlet, and an outlet, wherein the inlet is positioned axially and couples to the bottle, the inlet and the outlet having continuous fluid communication with the cavity;
• a bore formed through the body, wherein each end portion of the bore is open at the exterior of the body, the bore is not parallel to the axis, and the bore intersects the axis;
• an activator positioned in the body, the activator comprising:
• a depressor that opens the poppet valve,
• a position connector, and
• at least one pin disposed between the depressor and the position connector,
• wherein the activator does not obstruct the bore;
• and
• a position mechanism that moves the activator.

A system for receiving pressurized fluid from a provided bottle, wherein the bottle has a poppet valve biased in a closed position, wherein fluid flows from the bottle when the poppet valve is open, the system comprising:

• a paintball marker;
• an on-off controller comprising:
• a body having an axis and an inlet, wherein the inlet is positioned axially and couples to the bottle,
• a bore formed through the body, wherein each end portion of the bore is open at the exterior of the body and the bore is not parallel to the axis,
• an activator positioned in the body, the activator comprising:
• a depressor that opens the poppet valve,
• a position connector, and
• at least one pin disposed between the depressor and the position connector,
• wherein the activator does not obstruct the bore,
• a position mechanism that moves the activator, and
• a bolt positioned in the bore, wherein the bolt connects the on-off controller directly to the paintball marker.
