    摘要: To provide a mechanical seal in which degradation or tearing of a bellows does not occur, the spring constant of the bellows is reduced, and the fluctuation in the load due to stretching and contracting of the bellows is reduced. An inside-type mechanical seal comprising a sleeve (2, 20) fixed to a rotating shaft, and a cartridge (4, 40) fixed to a housing (3); a rotation-side sealing ring (5) being provided to the sleeve (2, 20); and a fixed-side sealing ring (6), which slides against the rotation-side sealing ring (5), and a bellows (7, 15, 30) for axially urging the fixed-side sealing ring (6), being provided to the cartridge (4, 40); the mechanical seal being characterized in that: the bellows (7, 15, 30) is made from a metal; and the metal bellows (7, 15, 30) has one end fixed to a case (8) for holding the fixed-side sealing ring (6) and another end fixed to the cartridge (4, 40), the plate thickness of the metal bellows (7, 15, 30) being set so as to be smaller than the plate thickness of the case (8) or the cartridge (4, 40).

    摘要: {Technical Problem} Provided is a capacity control valve that has no internal spring positioned in the bellows of the pressure-sensitive unit and also reduces the diameter of the valve element and that of the bellows to achieve size reduction and weight reduction. {Solution to Problem} The capacity control valve comprises: a pressure-sensitive body 50 positioned in the third valve chamber 38 to apply a bias force, by extending, in the direction of opening the first valve part 41, and also to contract as the surrounding pressure increases; an adapter 53 provided on the free end of the pressure-sensitive body in the extending/contracting directions and having a circular seating surface; a third valve part 43 that moves integrally with the valve element 40 in the third valve chamber 38 and has a circular engagement surface that opens/closes the intake-side passages 34 by engaging with and separating from the seating surface of the adapter; and a solenoid 60 that applies an electromagnetic drive force to the valve element 40 in the direction of closing the first valve part 41; wherein such capacity control valve is characterized in that: the pressure-sensitive body 50 is formed by a formed bellows made of material having greater yield stress than phosphor bronze; and the formed bellows has its diameter set smaller and its stroke longer than the diameter and stroke of a phosphor bronze bellows.
