  • Patent number: 8789771
    Abstract: A faucet is disclosed having a faucet base, a faucet spout mounted on the base and configured to swivel relative thereto, a female connector sleeve having an axial through channel, and a male connector sleeve having an axial through channel that is in fluid communication with the axial through channel of the female connector sleeve, the male connector sleeve being telescopically received within the female connector sleeve. The faucet further includes a first tube connected between one of the male and female connector sleeves and a fluid control valve, and a second tube separately formed from the spout, the female connector, and the male connector and connected between the other of the male and female connector sleeves and an outlet of the spout by internally extending within the spout. The male connector sleeve rotates within and relative to the female connector sleeve when the spout and second tube swivel relative to the base.

  • Patent number: 8430345
    Abstract: A faucet assembly is disclosed having internal carrier tubes, where the faucet spout can swivel relative to a faucet base without stressing the tubes. One tube connects a mixing valve to a connector sleeve. Another tube connects a spout outlet to another connector sleeve. The connector sleeves telescope within each other, have a seal there between, and are provided with a clip structure to hold them axially together while permitting relative rotation there between.

  • Publication number: 20090021004
    Abstract: A joint (1), especially of an exhaust system is provided for two axially adjacent ends (2, 3) of a tubular body (4, 5), respectively. Each tube end (2, 3) has a ring collar (8, 9) projecting radially outwards. A centering ring (6) is arranged axially between the tube ends (2, 3) and which has a plurality of collar segments (17) in the radial outward direction. Some of the collar segments (17a) project axially on one side of the centering ring (6) and axially overlap the ring collar (8) of one tube end (2), while the other collar segments (17b) project axially on the other side of the centering ring (6) and axially overlap the ring collar (9) of the other tube end (3) in the radial outward direction. A clamp (7) axially and radially overlaps the ring collar (8, 9) and the centering ring (6) in the radial outward direction.

  • Patent number: 6722705
    Abstract: A medical connector, usable to securely couple a first tubular medical device to a second tubular medical device, includes first and second fittings cooperating with the first and second medical devices, respectively. The first and second fittings may each include a nipple, a ferrule, or some other structure that is connected to the associated medical device and that is connectable to the other fitting. The second fitting may additionally include a tubular sleeve that slides over the second medical device and the ferrule or other component of the second fitting. The two components of the second fitting are sequentially connectable to the first fitting through distinctly different motions to provide a redundant, secure connection. For example, the first fitting may include a first set of left-handed threads and a second set of right-handed threads, and the components of the second fitting may have corresponding left-handed and right-handed threads.

  • Patent number: 6481762
    Abstract: A pipe coupling for attachment to a pipe includes a sleeve. One end of the sleeve is configured to receive a pipe end. The pipe coupling also includes an annular gasket disposed within the end of the sleeve for encircling the pipe end. The coupling includes a flanged assembly for compressing the annular gasket to form a seal between the pipe and the sleeve. The sleeve and the gasket are configured so as to define a leak path between an axially inner portion of the gasket and the inner surface of the sleeve, whereby pressurized fluid from the pipe may pass along the leak path so as to pressurize a radially outer surface of the gasket and urge the gasket against the compression flange to enhance the seal between the gasket and the sleeve.
