When one
of the selector switches is closed, an electro-chemical cell is activated,
and an electrochemical reaction takes place by which electrical energy is
converted into nitrogen gas. The gas is trapped in a hermetically sealed bellows-type
gas chamber. As the gas is produced, an internal pressure builds up, which
is applied against a piston. The piston then forces the lubricant out of the
cylinder and into the lube point. The strength of the electrical current determines
the amount of gas produced which, in turn, controls the rate of lubricant
flow and the length of time the Electro-Luber™ will operate.
To activate the Electro-Luber, the user merely selects the dispensing time
and amount of lubricant required, then clicks the appropriate switch(es) at
the top of the unit. A "BLIP" light is also activated. This light flashes
every 15 to 20 seconds, signaling that the system is in working order.
