  • Publication number: 20100090457
    Abstract: In a flareless-type pipe joint, a pressing surface 25, which presses a rear end portion of a ferrule 3 in the axial direction and toward the inner periphery of the ferrule 3, is formed in a joint body 1 or a coupling member 2 in which a cam surface 19 is not formed. The ferrule 3 has a groove 36 that extends radially outward from the inner periphery. By pressing the rear end portion in the axial direction and toward the inner periphery by means of the pressing surface 25, the distal portion of the ferrule 3 is pressed against the cam surface 19 and an edge portion 3b of the distal portion is deformed to bite into a pipe p. Further, an edge portion 3c of a rear end portion of the inner peripheral surface of the ferrule 3 is deformed to bite into the pipe p.

  • Patent number: 7585162
    Abstract: An object is to avoid generation of a collision sound of a second vane of a compression system comprising a multicylinder rotary compressor being configured to be used by switching of a first operation mode in which both rotary compression elements perform a compression work and a the second operation mode in which the only first rotary compression element substantially performs the compression work. When the second operation mode is switched to the first operation mode, discharge-side pressures of both the rotary compression elements are applied as a back pressure of the second vane, and thereafter an intermediate pressure is applied which is between suction-side and discharge-side pressures of both the rotary compression elements. When the first operation mode is switched to the second operation mode, a valve device interrupts flowing of a refrigerant into a second cylinder, and thereafter suction-side pressures of both the rotary compression elements are applied as the back pressure of the second vane.
