<p>PURPOSE:To improve the durability of a sealing member by forming an annular projection part on one of a rotary shaft side and a guide sleeve for guide- supporting the swing of a rotary driving plate and forming an annular recessed part on the other and setting the fitting relation in which a sealed space is formed on the swash plate max. tilt angle side between the both parts. CONSTITUTION:In the titled compressor, a piston 13 is moved in the longitudinal direction in a cylinder bore 12 by allowing a swing swash plate 11 to be moved in reciprocation through a rotary driving plate 8 by the revolution movement of a rotary shaft 4. The stroke of the piston 13 can be varied according to the differential pressure through the piston1 3 between the pressure in a crank chamber 2a and the intake pressure in the cylinder bore 12, and the tilt angle of the swing swash plate 11 which controls the compression capacity is varied. In this case, an annular projection part 5a is formed at the basic edge of a rotary supporting body 5, and an annular recessed part 9b opposed to an annular projection part 9c is formed into a guide sleeve 9. In the large capacity state, an annular recessed part 9b is fitted onto the annular projection part 9c, and a sealed space S is formed in the annular recessed part 9c.</p> |
