Abstract:
A swash plate-type compressor, comprising:a front housing; a cylinder block; a rear housing; a drive shaft rotatably supported by said front housing and said cylinder block; a rotor fixed to said drive shaft to be rotatable with said drive shaft; a plurality of pistons slidably disposed in cylinder bores formed in the cylinder block around an axis of said drive shaft; a swash plate movably mounted to said drive shaft and to which are connected said pistons via shoes; and a connection mechanism between said rotor and said swash plate such that an oblique angle of said swash plate changes with respect to a line oriented perpendicular to the axis of said drive shaft, wherein, said connection mechanism comprises a first arm projecting from said rotor, a link arm, and a second arm projecting from said swash plate, wherein said first arm and a terminal end of said link arm are connected rotatably by a first pin, said terminal part of said first arm drawing a circular locus as said first arm rotates around said axis, and said first pin extending in a direction tangential to said circular locus, and wherein said second arm and the other terminal end of said link arm are connected rotatably by a second pin extending in a direction parallel to said first pin, wherein a position of a pair of vertexes of said swash plate is offset from a geometric center of said swash plate.
