Abstract: A fill valve assembly comprises a valve body extending along a longitudinal axis and defining a fluid inlet, a valve seat and at least one fluid outlet, an axially slidable valve element arranged for axially slidable movement along the longitudinal axis, into and out of sealing engagement with the valve seat, the axially slidable valve element defining a first upstream conical surface having a first surface area and a second downstream conical surface having a second surface area, greater than the first surface area, and a fill sensor operative below a predetermined fill threshold to prevent the axially slidable valve element from establishing sealing engagement with the valve seat.

Abstract: A filling valve for a pressurized fluid container, including a tube with a longitudinal bore and a side port formed therein, a piston slidingly disposed in the tube, the piston being formed with a bore therethrough, a valve lever pivotally attached to a portion of the tube, the piston including a jutting portion which protrudes in a direction generally away from a bottom portion of the tube, a float arm attached to the valve lever, and a float mounted on the float arm, wherein when the float is positioned at a generally obtuse angle with respect to a longitudinal axis of the tube, the jutting portion of the piston is raised and supported by the valve lever, such that the piston is raised and does not block the side port, thereby permitting fluid flow through the side port, and wherein when the float is sufficiently buoyed by a fluid, the float arm swings upwards and the jutting portion of the piston is no longer supported by the valve lever and the piston moves downwards and blocks the side port, thereby prev
