It is suitable for farming, industrial & mechanical use. When the piston-type air compressor crankshaft rotates, the piston is in reciprocating motion driven by the connecting rod. The cyclinder displacement formed of cylinder wall, cylinder head and piston top surface will be will be changed in cycle. When the piston of compressor starts to move from the cylinder head, the working volume in the cylinder gradually increases. At this time, the air pushes the intake valve to enter the cylinder along the intake pipe. Until the working volume has become to the maximum, the intake valve closes. The piston of the compressor is moved in the reverse direction, the working volume in the cylinder reduces and the air pressure increases. When the pressure in the cylinder reaches and is slightly higher than the exhaust pressure, the exhaust valve opens. Until the piston moves to the extreme position, the exhaust valve closes. The above procedure is repeated when the piston of compressor moves backwards again. It is ideal to replace a defective unit or expand an existing compressed air system.
