Abstract
A dispensing apparatus having various features is described. The dispensing apparatus can receive a cartridge having a movable plunger configured to direct the fluid through a dispensing valve. The plunger can be movable under a force applied by air pressure. The cartridge can be inserted in the dispensing apparatus using a clamping and sealing mechanism and can be released using a cartridge ejector. The dispensing apparatus can include a ball valve having a ball defining an internal passageway that selectively aligns with a second internal passageway outside of the ball, a brush mounted via an elongating mechanism, and/or a gear train transmitting power from the elongating mechanism.
