摘要:
A construction is described for the reduction of pressure in a liquid that flows through an extended hollow body, characterised in that the hollow body comprises a unit that defines one or more flow channels, said channels show a stepwise, or continuously, increasing flow cross section calculated from an inlet end to an outlet end of the one or more channels. Also described is an application area for the construction. In addition, a valve construction is described for the reduction of the pressure in a liquid flow comprising a closing body that can be set between a position that closes for through-flow of liquid and a position that opens for full through-flow, where the closing body comprises one or more pipes in which bodies are arranged for stepwise or continuous increase of the liquid flow area and thereby the reduction of the liquid pressure.

A sound damping device comprises a first flow channel device (4) and a second flow channel device (6) separated from one another with an intermediate wall (8; 8a, 8b, 8c, 8d, 8e), said intermediate wall being at least partly provided with a sound attenuating means (9), wherein said first flow channel device (4) has a first inlet (5a) and a first outlet (5b) for a first flow and said second flow channel device (6) has a second inlet (7a) and a second outlet (7b) for a second flow. In accordance with the invention, at least said first flow channel device (4) is configured and adapted in such a way that a dynamic pressure difference is created over said sound attenuating means (9) with respect to the second flow channel device (6).

The module for managing mass flow and dampening pressure pulsations in the supply line of a gaseous fuelled internal combustion engine comprises a hollow body defining an expanded volume that is fluidly connected directly to a pressure sensor and a temperature sensor. The module is placed along the supply line of a gaseous fuel engine between a fuel pressure increasing device and the fuel rail that supplies fuel to the engine. The module can comprise a filter that filters the impurities from the gaseous fuel supplied to the engine and an overpressure protection device that can vent some of the gaseous fuel from the module to protect it for over-pressurization.
摘要:
Flow restriction to be fitted in a fluid line, consisting of a conduit part that has been produced from plastic by injection moulding and has been provided with a baffle closing the flow cross-section, wherein one or more openings have been made with the aid of a laser treatment. Each of these openings has a diameter of between 1 and 50 µm. It has been found that, when a large number of openings are used, if one of the openings becomes blocked for whatever reason this has hardly any effect on the total flow cross-sectional surface area. It is consequently possible to determine the flow conditions in the restriction very accurately and very reproducibly and consequently to establish the flow characteristics accurately. Such a flow restriction can be used, for example, in applications for dosing medication.
摘要:
A device for controlling fluid flow pressure and flow rate is disclosed. The device includes a first orifice plate, a second orifice plate housed in a tubular structure. The first orifice plate includes a first orifice of a first diameter (d1) and the first orifice is positioned near an edge of the first orifice plate. The second orifice plate includes a second orifice of a second diameter (d2) and the second orifice is positioned near an edge of the second orifice plate. The tubular structure has an effective diameter (D) comprising the first orifice plate and the second orifice plate placed at perpendicular direction to the fluid flow within the tubular structure, separated by an optimum distance (X).
摘要:
A water pipe structure of a branch pipe line (12) connected to a main pipe (22) for flowing water therethrough, wherein a cavity flow suppressing means (30) is installed between the main pipe (22) and the branch pipe line (12) or in the branch pipe line to suppress a cavity flow produced in the closed branch pipe line, whereby the adverse effect of a thermal stratification formed by the cavity flow on the pipe can be eliminated.
摘要:
A straining device (30) for a pressure control arrangement (10) for a pneumatic valve (100) of an air suspension system (110) for a vehicle (200a), in particular a utility vehicle (200b) comprises a radially extending base (32), an annular protrusion (34) and an annular lip (33). The annular protrusion (34) and the annular lip (33) project oppositely, along an axial direction (A), from the radially extended base (32). The base (32) comprises an inner base portion (32a) surrounded by the annular protrusion (34) and/or the annular lip (33). The straining device (30) comprises a plurality of fluid ports (31) arranged at the inner base portion (32a), wherein the fluid ports (31) are equidistantly distributed on a circle (C1, C2).
