<p>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.</p> |
