<p><P>PROBLEM TO BE SOLVED: To provide a piston type compressor suppressing leak of refrigerant by suppressing deformation of a rotary valve in a radial direction. <P>SOLUTION: The piston type compressor 10 is provided with a rotary valve 50 including an introduction passage 43 for introducing refrigerant from a crank chamber 17 to a compression chamber 34 defined in a cylinder bore 11a by a piston 31 on a rotary shaft 19. The rotary valve 50 is rotatably supported by a shaft hole 20 provided in the cylinder block 11 and is provided with a supply passage 41 communicating with the introduction passage 43 and the crank chamber 17 formed along an axial direction of the rotary valve 50. A bearing member 51 blocking the supply passage 41 and bearing load acting in a radial direction of the rotary valve 50 from an inside of the rotary valve 50 is attached on an end part side in an axial direction of the introduction passage 43 by the rotary valve 50. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
