3 outline drawing of Dino-Power Airless Sprayer (See Figure) 

 

The main working part of the sprayer is the double-acting air-driven high pressure painting pump. The 
reversing mechanism is the pilot all pneumatic control air-distributing reversing device with special form. 
When the compressed air flows into the cylinder, the piston moves to the upper part or lower part of the 
cylinder,  forcing  the  upper  or  lower  pilot  valve  to  operate.  The  control  air  drives  the  air-distributing 
reversing device to act in an instant, therefore realizing stable and continuous reciprocating movement of 
the piston of the air-driven motor. Thanks to the rigid connection between the piston and the plunger of the 
coating hydraulic pump, and the greater area of the piston than that of the plunger, the sucked coating is 
pressurized. The pressurized coating is conveyed to the airless spray gun via the high-pressure hose, 
and finally released of the hydraulic pressure and atomized at the airless nozzle, and then spayed to the 
surface of the target to form a coating layer. 

 

4 Operating instruction 

4.1 Before using, first check if all bolts, nuts, pipe connectors, and the connecting nuts and hose clamps of 
the suction system have been tightened. Learn carefully about the opening and closing direction of gate 
valve on each air circuit, and the rotating directions of pressure regulating valve and discharge valve (for 
the pressure regulating valve, turn the hand wheel clockwise to open and anti-clockwise to close).The
