(57) With reference to Figure 1, solvent cleaning apparatus 1 comprises a sealable enclosure
2 containing a solvent fluid discharge nozzle (Figure 7) in the form of a trigger-operable
discharge nozzle 130. The enclosure 2 is of electrically conductive plastics material
and is provided with an earth 95 whereby a substantial build-up of static electricity
does not take place. The enclosure 2 is provided with a substantially flat rectangular
access door 4 of toughened glass pivotally mounted about a horizontal axis, provided
with a pneumatic lock assembly comprising a piston 7 and cylinder 8. Located at the
uppermost region of the door 4 is a light unit 10 providing, in use, additional illumination
for the inside of the enclosure 2. The front panel 12 of the enclosure 2 is formed
with two circular access glove ports 14, 16, used to operate the trigger of the discharge
nozzle and to manipulate the article being cleaned. The solvent cleaning fluid is
stored in a reservoir box 18 formed with an inlet port 20 and an outlet port 22. In
use, the solvent fluid is drawn from the reservoir box 18, via a pick-up tube 32 by
way of a diaphragm pump 34, to be transported to the enclosure 2 via a cartridge filter
36. Once the solvent liquid has been discharged through the discharge nozzle within
the enclosure 2, it falls under gravity into a collection tray 40 to return to the
reservoir box 18.
