ABSTRACT:
An aerosol can containing a liquid propellant is placed on a can support platform (44). An operator actuated fluid control switch (84) provides pneumatic fluid or compressed air to a pneumatic cylinder (46) which continuously biases the aerosol can upward into engagement with a reservoir outlet (66) of a liquid reservoir (60). A sensing switch (52) senses movement of the can support, hence, the aerosol can. An operator actuated start valve (92) enables compressed air to be supplied cyclically (78a, 78b, 96) to a pump pneumatic cylinder (70). A pump (74) driven by the cylinder cycles a preselected number of times as counted by counter (90) to pump a preselected amount of liquid from the reservoir through the reservoir outlet and into the aerosol can. The sensing valve disables the pump in response to (i) failure to raise the can support, (ii) raising the can support beyond the normal position of interaction between the aerosol can and the reservoir outlet, and (iii) in response to the can support moving downward during filling. This prevents the pump from attempting to pump liquid (i) when the aerosol can is not raised, (ii) when the aerosol can or reservoir is absent, and (iii) when a can becomes elongated due to overfilling. An aluminum cabinet (12, 14, 16, 28) is mounted to a caste base (10). Doors (30, 32) selectively provide access to an aerosol can receiving region (22) and a reservoir receiving region (24). An interlock valve (100) disables the pump and the can raising cylinders when the aerosol can access door is open.
