Structure for supporting a swash plate at the maximum tilt angle in a variable displacement swash plate type compressor

A structure for supporting a swash plate at the maximum tilt angle in a swash plate type compressor, in which the swash plate is fitted around a drive shaft by support means to be swung, the peripheral edge of the swash plate is rotatably inserted into the bridges of pistons movably inserted into a plurality of bores formed in a cylinder, the central portion of the upper portion of the front surface of the swash plate is attached by a hinge unit to a rotor fixedly attached around the drive shaft, the center of the hinge unit coincides with the center of the bore into which a piston at its maximum compression stroke state is inserted, and a support projection is formed at a predetermined position of the front surface of the swash plate to define the maximum tilt angle by coming into contact with the rotor, wherein:

• when a connecting line (LC) passes through the center of the bore, into which the piston in the maximum compression stroke state is inserted, wherein the connecting line (LC) also passes through the center point of an imaginary circle that is formed by connecting the center points of the plurality of bores,
• the support projection is situated on an acting line (LP), which is spaced apart from the connecting line (LC) by a predetermined horizontal distance (LF) in the rotational direction of the swash plate, so as to define the position of the maximum tilt angle limit of the swash plate,
• and wherein the support projection is a single projection.
