ABSTRACT:
An apparatus for filling a pressurized can is provided that includes a pumping assembly having a piston for driving a liquid into the can. A cabinet encloses the pumping assembly and has a door which provides access to the pumping assembly. A first embodiment of the apparatus includes a manual lever arm assembly for driving the pumping assembly. A second embodiment of the apparatus includes a powered pneumatic cylinder for driving the pumping assembly and a control circuit for cycling the pneumatic cylinder. Preferably the control circuit includes a control valve for alternately supplying pneumatic fluid to upper and lower spaces of the pneumatic cylinder and a pair of accumulators for alternating the control valve. A third embodiment of the apparatus includes automatic means controls for driving the pumping assembly a selected number of piston cycles. Preferably, the automatic controls includes a stroke counter for counting the number of piston cycles and a shut-off valve triggered by the stroke counter to stop cycling of said piston when a predetermined number of piston cycles has been counted. Kits are provided for progressively upgrading the apparatus of the first embodiment to the apparatus of the third embodiment. Therefore, each cabinet is manufactured with openings for mounting the pneumatic cylinder and the automatic controls.
