Abstract
An axial piston compressor produces air supplied to an air system of a vehicle, typically a heavy duty truck through a plurality of pistons held within a stationary block, and the movement of the pistons is predicated through the control of a pivotal swash plate. The pistons are idle in a neutral position of the swash plate, wherein a pressure above the pistons in the cylinder block counterbalances a thrust generated by an actuator upon the plate positioned in a plane extending perpendicular to a drive shaft. The plate oscillates in response to a pressure drop above the pistons causing the actuator to expand toward the plate and exert a thrust exceeding the lowered pressure above the pistons and enabling the swash plate to provide the pistons with reciprocal motion.
