Methods and apparatus for a direct connect on-off controller

An on-off controller for controlling the 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 along a center of the body, a cavity, an inlet, an outlet, and a vent passage, wherein the inlet is positioned axially to the axis and couples to the bottle, the inlet and the outlet have continuous fluid communication with the cavity, and the vent passage provides sealable fluid communication between the cavity and the atmosphere;
• a bore formed through the body for receiving a provided bolt, 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 that opens the poppet valve, wherein the activator does not obstruct the bore, and the position of the activator defines operating states comprising:
• an on-state, wherein the poppet valve is open and the vent passage is sealed, whereby pressurized fluid enters the inlet;
• an off-state, wherein the poppet valve is closed and the vent passage is sealed, whereby pressurized fluid stops entering the inlet and remains in the cavity;
• a vent-state, wherein the poppet valve is closed and the vent passage is open, whereby pressurized fluid in the cavity vents to the atmosphere;
• a position mechanism that moves the activator, wherein the bore is positioned between the inlet and the position mechanism;
• and
• a seal that sealably contacts the activator in the on-state and the off-state, thereby sealing the vent passage.
