    摘要: A pulse valve arrangement includes a valve housing on which is fixed a control valve The valve housing includes a circular cylindrical portion with a valve member movably arranged therein. The valve chamber has an inlet adapted to be connected to a pressure medium source for allowing pressure medium to flow into the valve chamber and an outlet through which pressure medium flows out of the valve chamber. The control valve may be closed in which the outlet of the valve chamber is moved to a closing position blocking the flow of pressure medium, or may be opened in which the outlet of the valve chamber is moved to an opening position allowing a pulse of pressure medium therethrough. The valve member within the valve housing is freely displaceable within the circular cylindrical portion of the valve housing based on the pressure within the valve chamber as controlled by the control valve.

    摘要: High- or medium-voltage equipment comprising an induction-activated portion, a tank surrounding the active portion and filled with a dielectric fluid, such as oil, and passive acoustic reduction means for reducing acoustic waves coming from the active portion and propagating in the dielectric fluid. According to the invention, the passive means create an interference field that divides the propagated waves into two groups of waves of opposite phase that interfere with each other in a zone that is at a distance from the walls of the tank so as to at least limit the amplitude of the waves before they make contact with said walls. The equipment provides an effective solution for significantly reducing the noise that is propagated by the dielectric fluid medium.
