Abstract (en)

[origin: EP2096308A2] A swash plate type variable displacement compressor includes a crank chamber (16), a rotary shaft (17), a swash plate (23), a piston (29), a supply passage (42) and first and second bleed passages (48,58). The supply passage connecting the crank chamber to a discharge pressure region (39) is provided with a displacement control valve (35). The pressure in the crank chamber is varied by adjusting the opening of the displacement control valve. The first bleed passage (48) connecting the crank chamber to the suction pressure region is provided with a valve (50). The second bleed passage (58) constantly connecting the crank chamber to the suction pressure region (38) is provided with a throttle (59). The valve (50) operates to close the first bleed passage according to the magnitude of centrifugal force generated by the rotation of the rotary shaft.
