| (54) | Variable capacity swash plate compressor |
| (57) A swash plate (10) of a variable capacity swash plate is formed with a central through
hole (10d) and is axially movably mounted on a drive shaft (5) via an inner peripheral surface
of the central through hole (10d). The swash plate (10) is tiltably connected to a rotatable member (40) rigidly fitted
on the drive shaft (5) for rotation in unison therewith, such that the swash plate
(10) can rotate in unison with the drive shaft (5) as the latter rotates. A plurality
of pistons (7) are slidably received in respective cylinder bores (6) axially formed
through a cylinder block (1). A plurality of shoes (50) are connected to respective
pistons (7) and are relatively rotatable on a sliding surface (10a) of the swash plate (10) with respect thereto as the drive shaft (5) rotates, to
convert rotation of the swash plate (10) about the drive shaft (5) into axial reciprocating
motion of each piston (7). The amount of stroke of each piston (7) changes according
to an inclination of the swash plate (10). The drive shaft (5) is formed with a recess
(70) for shifting the rotational axis of the swash plate (10) toward a top dead centre
position side when the amount of stroke of each piston (7) becomes a maximum. |
