A swash plate type variable displacement compressor includes a cylinder
block defining a cylinder bore. A housing is fixed to the cylinder block
and defines a crank chamber. A drive shaft is rotatably supported by the
housing and the cylinder block. A swash plate is supported by the drive
shaft in the crank chamber and is inclinable with respect to the axis of
the drive shaft. A piston is accommodated in the cylinder bore so as to
define a compression chamber in the cylinder bore and is coupled to the
swash plate. A control mechanism includes a bleed passage for controlling
the pressure in the crank chamber. The compressor is formed such that
lubricating oil in the crank chamber is discharged into at least one of
the suction chamber, the discharge chamber and the compression chamber
while the inclination angle of the swash plate is substantially a maximum
inclination angle.
