  • Patent number: 8827318
    Abstract: A first component and a second component are connected with each other in a manner that a first passage of the first component and a second passage of the second component communicate with each other through a communication part. A seal component is disposed between the first component and the second component to provide a sealing between the first passage and the second passage. A ring component is arranged to surround the communication part, and is located adjacent to the communication part rather than the seal component. The ring component restricts the communication part from having an excess increase in a cross-sectional area.

  • Patent number: 8807382
    Abstract: A storage system useful for storing cryogenic liquids is disclosed. The storage system includes a storage vessel, insulation surrounding the storage vessel and a flexible vacuum jacket enclosing them both. The flexible vacuum jacket can be made from a flexible plastic film such as polyimide. Polyimide is preferred due to its ability to remain flexible at cryogenic temperatures. The inner volume of the flexible vacuum jacket is placed under vacuum such that the insulation is maintained under vacuum. The flexible vacuum jacket can collapse against and conform to the insulation when it is evacuated, saving substantially on volume. A fitting for combining multiple passageways is also disclosed, so that multiple passageways can proceed through the vacuum jacket through a single penetration.

  • Patent number: 7007981
    Abstract: In a connecting structure of a pipe of an air conditioning unit and a pipe joint for supporting the pipe, an insertion hole through which the pipe is inserted is formed within the pipe joint. The insertion hole has substantially a L-shaped cross-section and includes a first portion for receiving an end portion of the pipe and a second portion for receiving a flat portion of the pipe. The second portion is elliptical-shaped. In connecting the pipe to the pipe joint, the pipe is pressed into the insertion hole by a pressing punch. As a result, the pipe is bent and shaped along the elliptical shape of the second portion in the pipe joint, thereby forming the flat portion in the bend of the pipe. At the same time that the flat portion is formed, the pipe is clamped in the pipe joint.

  • Patent number: 6969094
    Abstract: A tube coupling for the detachable coupling of tube line sections of a high-pressure tubing system. The tube coupling includes two coupling blocks held together by a clamping screw, whereby one of the coupling blocks has a coupling plug that engages a plug socket provided on the other coupling block. A sealing ring is formed of a plastically deformable material and is enclosed between a front face of the coupling plug and a bottom-side sealing surface of the plug socket. In order to protect the sealing ring from being lost, damages and/or contaminated during assembly or opening and dosing the coupling, in a preassembled condition it is enclosed within a protective socket. To homogeneously load the sealing ring, the sealing ring is located at one point of a supporting triangle, the two other supporting points of being formed by a pair of supporting surfaces arranged side by side at an outer end of side flanges of the coupling blocks.

  • Patent number: 6908117
    Abstract: An alignment device for squarely aligning a conduit within a conduit port of a housing. The alignment device includes a connecting block having a conduit passage therethrough and into which the conduit is trapped. The connecting block has a fastener passage therethrough that is laterally offset from the conduit passage. A fastener is threaded into the housing and is offset from the conduit port. The fastener includes an alignment sleeve that mounts to a portion thereof. The connecting block mounts to the housing and the conduit fits into the conduit port, whereby the alignment sleeve pilots the fastener passage of the connecting block to squarely align the conduit within the conduit port.

  • Patent number: 6896298
    Abstract: A coupling assembly is provided such that a conduit having an annular bead and an annular seal can be slidably inserted into a specially formed port. The port is provided with a series of beveled surfaces that accommodate the seal in such a way that the conduit can be slidably inserted with a reduced risk of seal extrusion. An anchor plate is provided for bearing down on a side of the annular bead opposite the port in order to hold the conduit in place after insertion. The coupling assembly can include two or more conduits inserted into respective ports having the series of beveled surfaces. According to one embodiment, the port(s) also includes a counterbored surface at a depth of the port at or near where the end of the conduit reaches.

  • Patent number: 6893052
    Abstract: A connecting arrangement for coolant lines includes a first coupling piece, connected seal-tight to a first line endpiece, and a second coupling piece, connected seal-tight to a second line endpiece. The coupling pieces each have radially extending sealing surfaces on the side facing toward the other coupling piece. A sealing ring is mounted between the sealing surfaces. The coupling pieces are joined to each other via a screw arranged laterally offset from the sealing surfaces so the line endpieces connect to each other via respective bores in the coupling pieces. A form body between the coupling pieces arranged at a spacing from the screw on the side facing away from the sealing surfaces is configured so a lever action occurs when the coupling pieces are joined to each other leading to a uniform pressing together of the sealing ring between the sealing surfaces of the coupling pieces.

  • Patent number: 6851446
    Abstract: Adaptor assemblies are detailed. Preferably for connecting automatic pool cleaning apparatus to return lines of swimming pool water-circulation systems, the assemblies utilize spurs that may affirmatively grip, or cut or gouge into, the return lines to retain the adaptors in position. Releasing the adaptors may occur with use of a release line which retracts the spurs when activated. Avoiding release of the spurs through rotation of the assemblies allows rotation for other purposes as, for example, to connect the device to a hose or other apparatus. A bellows or other assembly additionally may be included with the assemblies to facilitate their sealing against walls or other surfaces in which the return lines are embedded.

  • Publication number: 20040245773
    Abstract: A plug connection device (1), in particular for securing and tightening fluid couplings (11), has a holding device with a holder (14), a plug-in element (26) and an extension spring element in the form of an annular extension spring (23). The annular extension spring (23) acts as a wedge between an annular surface (32) formed on the plug-in element (26) and an annular rim (19) formed on the holder (14). The annular extension spring (23) can perform a rolling movement around its chord center axis (24). A particularly low static friction is present here because of the support of the annular extension spring (23) on the annular rim (19), which permits a continuous automatic re-tightening of the holding device (12).
