摘要： Disclosed is a damping device to be incorporated into fluid systems, particularly hydraulic systems, said damping device comprising an expansion hose (2). An essentially rigid damper pipe (15) which is oriented counter to the direction of flow is disposed inside the inner space of said expansion hose (2). The damper pipe (15) is provided with a completely closed wall, resulting in a good damping effect. Preferably, the damper pipe (15) is significantly less flexible in the radial direction than the outer expansion pipe, whereby the damping effect is substantially enhanced.

摘要： The inventive sliding valve (8) comprises a slide (18), which is mounted in a manner that enables it to move transversal to the passage channel (11). This valve is provided with an asymmetrical design whereby enabling the pressure prevailing in the passage channel (11) to reach a side of the slide (18) via suitable ducts (25, 26), whereas the other side is not subjected to any pressure or only to a constant low pressure. A pressure spring (29) works counter to the pressure and holds the slide (18) in the open position. In the event the fluid pressure prevails, the slide (18) is displaced into the blocking position in which it remains until the pressure falls below the switching limit once again.

摘要： For connecting flexible corrugated hoses, which are not provided with fittings, for transporting preferably gaseous media in connection with high-pressure applications, a holder 3 is provided, which receives an exposed end of the corrugated pipe 6 of the flexible corrugated hose 2 and is pressed together with it to form a metallic seal. The metallic seal is achieved by the surface pressure between the interior wall 18 of an element 16 of the holder and the ribs 8 of the corrugated pipe 6. Elastomeric seals 24, 25, as well as a soldering joint 34, if desired, can be provided as aids. However, in connection with a preferred embodiment the required sealing is already achieved by the strong pressure against each other of the metallic exterior of the corrugated pipe 6 and the metallic interior of the element 16. A further element 17 of the holder 3 fixes a section 28 of the sheathing 11 of the flexible corrugated hose 2 in the axial direction, as well as in respect to tilting movements, so that pivot movements of the flexible corrugated hose 2 do not lead to a relative movement between the corrugated pipe 6 and the holder 3, in particular the element 16. Thus, the sealed area remains unaffected, even in case of mechanical tensile or bending stresses of the flexible corrugated hose assembly 1.

摘要： A servo drive includes a hydraulic cylinder. The hydraulic cylinder comprises a piston that is mounted in the cylinder and that delimits two working chambers. Relief lines connected to the working chambers via control orifices may aid the definition of the right and left end positions of the piston. The control orifices are exposed by the piston in its respective end positions, thus relieving the pressure in the active working chamber. An end stop, which may be predetermined by the position of the control orifices may be formed by the pressure relief that occurs at the relevant location in the working chamber. Such measure can relieve the pressure in the hydraulic pump, for instance in end stop positions.

摘要： 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.
