The valve may have a housing with an inlet and an outlet. A hollow valve piston is movable to admit fluid from the inlet into a cylinder through openings in the wall of the piston and to free openings in the wall of the cylinder for the fluid to pass to the outlet. The openings in the piston are of smaller flow area than those in the cylinder and such that the pressure drop at either holes does not fall below a given value. In this way the substantial pressure drop occuring at a single stage and consequent noise or cavitation are avoided.

Thus, compressed air, which has passed through the pneumatic device, passes through the acoustical absorbent of the silencer. At this time, almost all noise is absorbed by the acoustical absorbent.

Noise and vibration suppressors

Номер: US6983820B2
Принадлежит: Avon Polymer Products Ltd

In order to form a noise suppressor in a hose of e.g. a motor vehicle, modular portions are connected in series to define suppression chambers with particular noise suppression characteristics. Those characteristics are due to the volume of each chamber, to the size of the apertures from the chambers to the central duct of the suppressor, and optionally due to spacers which are inserted into at least one aperture of the chambers to alter the effective open area of that aperture. Such spacers may also be used in which the noise suppressor is not modular. Where modular portions are used, it is preferable that each chamber is bounded by parts of two modular portions. A wall of one modular portion may then close the chamber in another modular portion, making the manufacture of the modular portions easier. Also disclosed is the use of a mass acting as a damper, which may be a noise suppressor as previously discussed, within a hose. The mass is connected to the hose by resilient means, e.g. electrometric material.

Принадлежит: VACCO Industries Inc

A co-axial stack of annular disks, each of which is preferably made of a sheet metal so thin as to be individually flexible, is held under axial compression to define an essentially rigid column. Each disk, on at least one surface thereof, is integrally formed with a plurality of radially extending depressions, preferably of non-circular cross-section, whose sidewalls diverge radially outwardly away from one another, each such depression defining a diffuser passage with a surface of an adjacent disk. The disks are formed with substantially identical patterns of depressions and the plurality of disks are substantially identically angularly oriented with respect to each other so that the land areas between depressions are directly superimposed on each other to sustain the axial compression of the stack without deformation of the individual thin disks. The compressed stack provides a very high density of inlet and outlet orifices on the inner and outer walls thereof whose interconnecting passageways are opened or closed by axial movement of a valve member through the central passage defined by the stack. The gradient of increase in cross-sectional area of the diffuser passages from inlet to outlet is calculated to maintain a substantially constant velocity of the gas flow therethrough, with a gradually increasing specific volume gradient from inlet to outlet.

The inlet of the labyrinth assemblies is formed according to a substantially circular configuration to have a predetermined inlet area while the outlet is formed according to a substantially scalloped configuration to provide an outlet area greater than the inlet area. The scalloped configuration of the outlet yields an outlet area which is also greater than if the outlet were of circular configuration. The scalloped outlet configuration also makes the labyrinth assembly less susceptible to circumferential thermal stresses resulting from high temperature fluids passing through the device producing high temperature inlet conditions and low temperature outlet conditions.

Pipeline and mehtod for producing the same

Номер: US20110036440A1
Принадлежит: Nexans SA

A pipeline for the transport of a pressurized flowable medium, consisting of a metal tube corrugated transversely to its longitudinal direction and of a hose which is arranged in the same and consists of plastic. In the position of use the hose bears against the inwardly pointing wave troughs of the metal tube, which hose has a multiplicity of holes separated from one another in the wall of the same over its entire axial length. The wave troughs of the metal tube penetrate slightly into the surface of the hose so as to fix the latter with respect to axial loads.
