  • Patent number: 8689837
    Abstract: A downspout extension has a low-profile to direct rainwater away from a building. A transition adapter can be used to transition from a generally circular or square cross-section of a downspout to a low-profile cross-section of a corrugated duct of the extension. The extension can include internal supports to withstand being stepped on and can have a generally rectangular or trapezoidal cross-section with a longer width than height. The corrugated duct can also be comprised of integrated accordion corrugation sections and transverse non-collapsible ribs to give the corrugated duct extension greater flexibility. The extension can be connected to a downspout using a flexible elbow duct, a downspout connector, and a downspout adapter. The transition adapter of the extension can also be connected directly to a downspout.

    Abstract: The present invention provides a delivery system for providing an atomized treatment agent like a cleaner or lubricant to a specific internal location of a closed mechanical system like an internal combustion engine. The atomized treatment agent is delivered via a flexible, non-rigid conduit to the desired internal location of the engine between, e.g., the ID/OD coupling joint between the air inlet hose and the throttle body. A special conduit support guide, the end of which is inserted through the ID/OD coupling joint, provides the proper geometry for gently configuring the conduit to enter the ID/OD coupling joint without crimping and controlling the directional approach and distance of the conduit free end inside the engine.

  • Patent number: 8607827
    Abstract: A low profile downspout extension is formed in multiple segments including a flexible conduit, a splash block and an extension. The splash block transitions from a circular inlet into a low profile pentagon configuration with a central bead along the top surface of the low profile body portion to define an apex of the pentagon shape. The body portion is wider than the diameter of the circular inlet but has a height at the central bead that is more than half the diameter of the circular inlet. The body portion has ribbed side walls to strengthen the splash block without requiring internal reinforcement. The bottom surface of the splash block defines a flow path that extends generally linearly from the bottom of the inlet opening to the bottom of the pentagon-shaped outlet. An open configuration for the splash block provides an alternative above-ground splash pad structure for connecting to downspouts.

    Abstract: The invention provides a fluid transfer pipe for filling a cooling circuit of a motor vehicle, and the method for manufacturing said pipe. This pipe includes at least one corrugated bendable portion based on at least one thermoplastic material and which includes a succession of radial reliefs axially spaced so as to form hollows between them, each relief having two frontal regions linked together by an intermediate region, the frontal regions of each relief each having one and the same overall polygonal contour defining at least three straight sections forming flats for this relief and interlinked by rounded sections forming bulges, and the contours of the successive reliefs being adapted to allow for the stripping of the corrugated portion from two hemicylindrical shells of a mould along a single axial stripping plane.

  • Patent number: 8146620
    Abstract: A corrugated pipe having a non circular in cross section profile and at least one generally elongate wall section is improved by using a variable height corrugation in the length of the elongate wall segment. The variable height corrugation is of a greatest height at a center portion thereof and decreases in height towards the end points of the elongate wall segment. A spanning type truss arrangement is formed that opposes inward deflection of the straight wall segment.

  • Patent number: 8043681
    Abstract: In a method of making a hybrid structure, at least one support body is fixed in a tube component which is then placed in an injection molding tool. An injection-molded part is injection-molded to an outer surface of the tube component in an area of the support body. As a result, the tube component is inwardly deformed, when regions adjacent to the support body are exposed to an injection pressure, and forms indentations for engagement of the injection-molded part.

  • Publication number: 20110073209
    Abstract: A flexible tube includes a bellows tube, an interlock tube placed inside the bellows tube, and upstream-side and downstream-side joint pipes coupled to opposite ends of the bellows tube. Diameters of fixing end portions located at opposite ends of the interlock tube are made larger than a diameter at a middle portion of the interlock tube, extension portions of the upstream-side and downstream-side joint pipes are fitted and fixed to inner peripheral surfaces of the fixing end portions of the interlock tube, and a depth of each of valley portions of a bellows portion of the bellows tube located over the fixing end portions is smaller than a depth of other valley portions of the bellows portion. Accordingly, it is possible to achieve the downsizing of the flexible tube that is connected to an exhaust system being continuous with an engine to dampen vibrations in the axial direction of the exhaust system.

  • Publication number: 20110056582
    Abstract: An exhaust-gas conduction component that is effective as a vibration decoupling element and can be installed in an exhaust-gas system for conducting the exhaust gases of a motor vehicle internal combustion engine. The exhaust-gas conduction component (1) has an outer pipe (2) with a corrugated metal tube section (3; 4) and an inner pipe (8) that is coaxial with the outer pipe (2) and separated from the latter by an annular gap. The outer pipe (2) also has a smooth central section (5), first and second corrugated metal tube sections (3; 4) and smooth first and second end sections (6; 7). The inner pipe (8) is permanently fixed to the outer pipe (2) by a continuous joint (9) extending around the central section (5) and the rectilinear exhaust-gas conduction component (1) is approximately axially symmetrical in relation to a central transverse axis (10). The exhaust-gas conduction component is especially suitable in utility vehicles for linking an emission control unit to an internal combustion engine.
