A painting system having a supply section, a delivery and control section, and an applicator section. The supply section comprises a peristaltic type pump. The delivery and control section comprises a unitary tube having a delivery passageway and an air pressurizing passageway. A pressurizing control switch at the location of the applicator acts through the air passageway to control operation of the pump. The applicator section has a housing which provides a uniform pattern of distribution passageways for uniform application of paint.

A painting system, comprising: a. a supply section comprising a pump adapted to pump liquid paint from a paint source; b. an applicator section comprising an applicator to dispense the paint from the applicator; c. a delivery and control section comprising: 1. a delivery tube having a receiving end to receive the paint from the pump, a delivery passageway to carry the paint, and a discharge end to deliver paint to the applicator; 2. an actuating tube having an interior passageway distinct from said delivery passageway to contain air, said tube having a first end proximate to the supply section and a second end proximate to the applicator section; 3. a pressure responsive pump switch operatively connected to the actuating tube and to the pump to cause the pump to operate, said switch having an on position and an off position, said switch defining an air pressure chamber which, when pressurized to a first higher pressure level, holds said switch in said on-position, and when at a second lower pressure level, enables said switch to move to said off-position; 4. a pressurizing switch proximate to the applicator section and operatively connected to the second end of the actuating tube, said pressurizing switch having a release position where air pressure in the actuating tube is decreased to said lower pressure level to move the pump switch to its off position to inactivate the pump and interrupt delivery of paint, and a pressurizing position to raise pressure in said air pressure chamber so as to move the pump switch to its on position to activate the pump and to maintain said pressure at said higher pressure level so as to hold said pump switch in said on-position to cause delivery of the paint, said pressurizing switch comprising a switch housing, compressible tube means mounted in said switch housing and having a lengthwise axis, a first end, opening to ambient atmosphere, and a second end, opening to the second end of the actuating tube, and a manually operable pressure control member movable along said lengthwise axis on an actuating path from said release position where said control member is proximate said first end, to said pressurizing position where said control member is proximate said second end of the tube means, said control member being mounted to said switch housing in a manner that when said control member moves from said release position, said control member squeezes said tube means at a location proximate the first end of the tube means at an intermediate squeeze-off position to close said tube means to ambient atmosphere, and as said control member moves from said intermediate squeeze-off position to said pressurizing position, said control member squeezes said tube means along said lengthwise axis to pressurize the air pressure chamber of the pump switch to said higher level.
