Gas hydraulic airless sprayer

摘要

The frame 12 of a gas hydraulic sprayer 10 has a rear bumper 12a to be tilted up so that the immersion or suction tube 14 clears a paint container and rests on the bumper 12a. The hydraulic motor 16 consists of a piston 38 with a magnet 41, two sensors 47, a solenoid valve 32 and a microprocessor 18 which directs fluid through a solenoid operated valve 32 to the top or bottom of the piston 38. A secondary cooler or radiator 20 is made of tubing and attached to the hydraulic pump case 22 and routed in front of the fan and back to the oil reservoir.
