The present application also relates to an aircraft assembly comprising the duct stringer and the fluid transporting conduit.

A pipe junction includes a corrugated pipe including a pipe wall having an inner pipe wall and an outer pipe wall, the outer pipe wall having a plurality of peaks and a plurality of valleys disposed between the plurality of peaks, and an opening through the pipe wall. The corrugated pipe junction includes a hub and sleeve assembly received within the opening of the pipe wall, the hub and sleeve assembly including a hub received within the sleeve. When the hub and sleeve assembly is received within the opening of the pipe wall, a compressive seal is formed between the hub and sleeve assembly and the inner pipe wall such that the hub and sleeve assembly is sealingly engaged with the inner pipe wall around an entire circumference of the hub and sleeve assembly.

A connector assembly including a plate (10) having an orifice (10a) and a spigot (12), the spigot (12) having an internal flow path for liquid, and connector means (14) for connecting the spigot (12) to the metal plate (10) so as to guide the liquid flowing in the flow path through the orifice (10a), the connector (14) including a protruding collar structure (16) surrounding the orifice (10a). The connector means (14) further includes a ring-shaped snap-on module (18) configured to be fitted over the collar structure (16), the snap-on module (18) including a cylindrical insertion part (18a) configured to be inserted into an orifice (10a) of the collar structure (16), wherein a remote end of the cylindrical insertion part (18a) in the insertion direction is provided with first snap-on structures engaging with the collar structure (16).

A drip irrigation lateral connector to a feeder pipe, a feeder pipe adapted for mounting those connectors and an irrigation system comprises a feeder pipe with those connectors and drip irrigation laterals that are mounted to those connectors by standard drip irrigation lateral connectors, wherein each of those connectors comprising a bushing and a sleeve element and wherein the sleeve is formed with a multi-armed circumferential array that are adapted for snap mounting of said sleeve into said bushing or disassembly from it by linearly pushing the sleeve towards the bushing or linearly retrieving the sleeve from the bushing while disconnecting the sleeve's multi-armed circumferential array from the bushing.

A cooling element for an electric component, in particular an electric battery of an electric or hybrid vehicle, includes: a pipe for a coolant, having two apertures at two ends of the pipe, and at least one secondary aperture. At least one external connecting pipe fluidically connects to the at least one secondary aperture. The external connecting pipe is connected to the secondary aperture through a quick-coupling.

A reducing tee that includes a main portion extending from a first end to a second end with an intermediate portion disposed between the first end and the second end. A main passageway extends from the first end to the second end, and a branch extends outwards from the intermediate portion containing a passageway in fluid communication with the main passageway. A water trap having a hollow body with a first open end, a second open end, an exterior surface, an interior surface, and a linear passageway extends between the first open end and the second open end disposed within the reducing tee.

A bulkhead penetrator comprising a body having an interior and an exterior. An element having a first pressure is disposed within the body's interior in a first pressure region. An inner penetrator is configured to permit a transfer of the element from the body's interior past the physical boundary to the exterior of the body in a second pressure region having a second pressure, the inner penetrator having an interior surface exposed to the first pressure region and an exterior surface exposed to the second pressure region. An outer penetrator is configured to permit the transfer of the element from the interior of the body past the physical boundary to the exterior of the body in a third pressure region having a third pressure. An inner-outer connector connects the inner penetrator to the outer penetrator. Sealing mechanisms may prevent the transfer of the element from the first pressure region.

A pipe erroneous assembly preventing structure includes a pipe and a case. The pipe includes a stay in which a stay-side abutting portion and a stay claw portion intersect with each other in an L shape. The case includes a hole forming portion; a first protrusion portion provided in the hole forming portion; a case-side abutting portion which is recessed in the first protrusion portion and to which the stay-side abutting portion of the stay abuts, and a second protrusion portion protruding from the case wall surface. In a case where a length of the stay claw portion in the insertion direction is set to Ls, a distance from the case wall surface to the case-side abutting portion is set to Lg, and a distance from the case wall surface to the second protrusion portion is set to Lp, LgLp<LsLg is satisfied.

The present disclosure is, in one aspect, directed to a locking assembly for securing a sample tube assembly to a sample manifold of a measurement system. The locking assembly includes a ramp block having one or more slots defined therein and configured to at least partially receive a portion of the sample tube assembly. The ramp block also includes a plurality of surface features defined therealong and configured to engage and move the sample tube assembly toward and into engagement with the sample manifold. The ramp block further is movable between a plurality of positions including an open position for allowing the sample tube assembly to be received through the one or more slots or openings, and a closed position substantially sealing the sample tube assembly against or within the sample manifold. Other aspects also are described.

A quick fit connector is disclosed for the return line of fuel injectors in an internal combustion engine. The connector includes a T- or L-shaped connector body having at least one connection branch insertable in a fuel return port of a fuel injector, a lower plate, an upper plate and a spring clip. The upper plate is slidingly mounted on the spring clip and the connector body and is movable between an unlocked position, in which the spring clip is in unloaded condition and free from any engagement with the fuel injector, and a locked position in which the spring clip is in loaded condition and engages the fuel injector and the lower plate.
