<p>PURPOSE:To sufficiently reduce the discharge capacity by displacing a slant plate in the axial direction of shaft, changing the inclination angle to change the stroke of piston and the discharge capacity, and forcing the slant plate to one compression chamber side through the discharge pressure introduced to the other chamber. CONSTITUTION:When a shaft 100 is rotated, a slant plate 160 is swung and rotated inside a slant plate chamber 70 through a transmission part 150 and a connection part 161, and a piston 111 is reciprocated through a shoe 169. As a result, compression chambers 91, 92 are expanded and shrinked to dis charge compressed coolant to a discharge chamber 115. In this case, when an output passage 204 is communicated with an intake pressure passage 202 through a selector valve 201, the pressure in a control chamber 200 varies to displace a drive piston 190, thereby the inclination angle of slant plate 160 varies to change the discharge capacity. Further, when the discharge pressure in the chamber 115 is introduced with a control valve 301 through an introducing hole 300, the stroke of piston 111 is made small sufficiently.</p> |
