PURPOSE:To have a rotor or the like with its axial dimension changeable only through replacement of the cover etc., and also to offer possibility to maintain the joint parts of the side blocks etc. airtight from outside the compressor. CONSTITUTION:The axial dimensions only of covers 18, 18' and bolts 15, 16 are required to change in accordance with the axial dimensions of the cam ring 1, rotor 5 and vane 7 and this type of covers 18, 18' can be manufactured extremely easily by cutting a cylinderical material into appropriate length. Because the outside circumferential surfaces of the cam ring 1 and the side blocks 2, 3 are sealed from outside the compressor by a cover 18 or O-rings 17, 17, the leaked refrigerant through the joint parts A, B, C, D is prevented from leaking further to outside the compressor. Accordingly, high precision processing of these point parts or use of much sealing material can be eliminated. |
