SWASH PLATE TYPE VARIABLE DISPLACEMENT COMPRESSOR

摘要

A swash plate type variable displacement compressor includes, a housing, a swash plate disposed in the housing and having therethrough an insertion hole, a rotary shaft inserted through the insertion hole of the swash plate, a plurality of pistons engaged with the swash plate, and a connecting member disposed between the rotary shaft and the swash plate and connecting the rotary shaft and the swash plate so as to change inclination angle of the swash plate relative to the rotary shaft. A pair of projections are provided in the insertion hole so as to extend toward the rotary shaft and restrict the movement of the swash plate relative to the rotary shaft. The paired projections are spaced away from each other so as not to be in contact with the rotary shaft simultaneously.

1. A swash plate type variable displacement compressor comprising:
a housing; a swash plate disposed in the housing and having therethrough an insertion hole; a rotary shaft inserted through the insertion hole of the swash plate; a plurality of pistons engaged with the swash plate; and a connecting member disposed between the rotary shaft and the swash plate and connecting the rotary shaft and the swash plate so as to change inclination angle of the swash plate relative to the rotary shaft, wherein the swash plate has a first point at which one of the pistons is positioned at a top dead center and a second point at which one of the positions is positioned at a bottom dead center, wherein the swash plate is variable relative to the rotary shaft in a direction that is perpendicular to an axis of rotation of the rotary shaft and a line connecting the first point and the second point of the swash plate, wherein when the inclination angle of the swash plate is changed relative to the rotary shaft, stroke lengths of the pistons are changed to vary displacement of the compressor, wherein a pair of projections are provided in the insertion hole so as to extend toward the rotary shaft and restrict the movement of the swash plate relative to the rotary shaft, wherein the paired projections are spaced away from each other so as not to be in contact with the rotary shaft simultaneously.
