  • Publication number: 20150118074
    Abstract: In a swash plate type variable displacement compressor, a lug plate includes a cylinder chamber and first and second guide surfaces. Inner peripheral edges of the first and second guide surfaces are defined respectively at parts where the peripheral edge of the cylinder chamber and the guide surfaces overlap with each other. When the inclination angle of a swash plate of the compressor is maximum, first and second guided surfaces and the first and second guide surfaces, respectively are brought into line contact with each other at a first position. At this time, first and second slide contact widths are maximum. When the inclination angle of the swash plate is minimum, the first and second guided surfaces and the first and second guide surfaces, respectively are brought into line contact with each other at a second position. At this time, the first and second slide contact widths are minimum.
