Abstract: The invention relates to a method for manufacturing a throttle (3) in a hose (1), characterized in that the wall (13) of the hose (1) is manufactured in such a way that the interior of the hose (1) has a constriction in part of its length.

Abstract: A flexible cord-like hollow object for the transportation of media is provided with an inner zone enclosed by a casing having an inner layer, a middle layer and an outer layer. A barrier layer, which is impermeable to volatile molecules of the medium to be transported, is integrated into the casing on the outer surface of the inner layer between the inner layer and the middle layer. The barrier layer comprises sub-elements that are arranged in a scale-like manner.

A barrier layer, which is impermeable to volatile molecules of the medium to be transported, is provided on the casing surface facing the inner zone. The barrier layer comprises sub-elements that are arranged in a scale-like manner.

Abstract: A hose for transporting preferably gaseous media at high temperatures and under high pressure has a corrugated interior surface with depressions and elevations, and at least one insertion element that can be inserted in one end. The hose is characterized in that, in the region of contact between the interior surface of the hose and the exterior surface of the insertion element, at least one gasket element of crystalline material is provided. The gasket element is metal, preferably a lead or copper alloy.

Abstract: A quick-fitting pipe union is proposed with an insertion component, a socket component and at least one sealing element. The sealing element (7) excels by virtue of the feature that it comprises a connecting section (9) and two lips (11) that extend outward from the connecting section (9).

Abstract: A coupling arrangement connects two elements with each other. The coupling arrangement includes a plug element and a bushing element which are configured in such a manner that they can be plugged together and locked in position by means of an expandable retaining ring. An axially movable release arrangement cooperates with the retaining ring in order to release the locking mechanism. The coupling arrangement is characterized in that the release arrangement (41) comprises a release sleeve (43), which can be closed with a cover (51) on its side facing away from the bushing element (5), and that a blocking device (55) is used to prevent an inadvertent release of the coupling.

Abstract: A flexible continuous hollow element configured as a jacket enclosing a hollow space for the transport of media includes a blocking layer (26) which is an integral part of the jacket (12). The blocking layer is impermeable to volatile molecules of the medium to be transported and is configured as a fabric layer (28) enclosing the interior space (14) formed by the layer (18) of the jacket (12).

Abstract: A coupling assembly for connecting two tubular elements, in particular ends of two tubes of an air-conditioning system, includes two inter-engaging locking parts which, for the purpose of achieving a locked position, can be rotated with respect to one another and can be displaced with respect to one another in the axial direction. The locking parts utilize a bayonet locking feature and include at least two sub-elements, the sub-elements being fixed in the radial direction by two inter-engaging sleeves.

Abstract: The invention related to a drive system with at least two hydraulic actuators, which are supplied with a hydraulic fluid by means of at least one pump. The drive system comprises at least one further second pump (15′) arranged parallel to the first pump (15), wherein the pumps are bi-directionally speed-regulated, and a valve arrangement (59) with one inlet per pump (61.1, 61.2), wherein each one of the inlets is connected to a pump (15), and with a number of outlets (63.1, 63.1′, . . . 63.4, 63.4′) which are connected to the actuators (1.1 . . . 1.4), wherein the inlets (61) can be connected to the outlets (63) in a pre-determined manner.

Abstract: Apparatus damps pulsations of a fluid conveyed through a conveying device. The fluid is led by way of a first tubular element into a cavity formed by a flexible element and emerges from the cavity by way of a second tubular element. The tubular elements are arranged within the cavity in the flexible element. The length of each of the individual tubular elements is less than the length of the cavity; however, the sum of the lengths of the tubular elements is greater than the length of the cavity.

Abstract: An arrangement for connecting two pipe ends comprising a respective closure part around each of the pipe ends. The closure parts are connected together in a bayonet-type connection. One closure part includes an annular surface with a first part parallel to a sealing device placed between the pipe ends and with a second part inclined with respect to the sealing device. The latter part draws the closure parts and the pipe ends together as the closure parts are rotated relatively toward each other and as the one closure part is guided along the inclined portion of the annular surface. A respective sealing surface is provided on each of the pipe end parts. The sealing surfaces are brought axially toward each other by movement together of the closure parts.

Abstract: A device for damping the sound emission from oscillatory components of a fluid container of a hydraulic system, primarily in a motor vehicle. At least one vibration damping mass is coupled to the wall of a component subject to sound damping. The mass is adapted to the vibration to be damped by selection of material, shape, and/or position on the wall. For example, the mass is a rib fastened to the wall or a strip adhered to the wall. In an alternate embodiment, the container has an inner and an outer wall with a gap between them. The gap is either evacuated, filled with a sound absorbing material or ribs on the wall extend in the gap or inside the inner wall.
