With FS-10 Compressor

The FS-10 A/C compressor is:
^ a swashplate design.
^ ten-cylinder.
^ aluminum.
^ tangential design mount.

Operation is as follows:
^ The compressor mainshaft is driven by a drive belt from the engine crankshaft pulley.
^ A one-piece, lip-type seal (replaceable from the front of the A/C compressor) is used to seal the shaft opening in the assembly.
^ Five double-acting pistons, positioned axially around the compressor shaft, operate within the cylinder assembly.
^ The pistons are actuated by a swashplate that is pressed on the compressor shaft.
^ The swashplate changes the rotating action of the shaft to provide a reciprocating driving force to each of the five pistons.
^ This driving force is applied, through shoes, to the midpoint of each of the double-end pistons.
^ Reed-type discharge valves are assembled on the valve plate which is located with the suction reed valve between the cylinder assembly and the head at each end of the A/C compressor.
^ The heads have connecting gas-tight passageways through the cylinder assembly which direct the refrigerant gas to the suction and discharge ports located in the rear head.

A magnetic A/C clutch is used to drive the compressor shaft.
^ When voltage is applied to the A/C clutch field coil, the A/C clutch (which is solidly coupled to the compressor shaft) is drawn rearward by magnetic force toward the A/C clutch pulley which is driven by the engine drive belt.
^ Magnetic force locks the A/C clutch and the A/C clutch pulley together as one unit.
^ The compressor shaft then turns with the A/C clutch. When voltage is removed from the A/C clutch field coil, springs in the clutch plate and hub assembly move the A/C clutch away from the A/C clutch pulley.
