ABSTRACT:
For the damping of high-frequency vibrations in liquids under high pressure in conduit systems there serves a diaphragm (2) loaded by a spring (3) and surrounded on all sides by the liquid of the conduit system. When the liquid is stationary the diaphragm (2) acts as barrier in a free flow cross-section of the conduit system. When the liquid is flowing the diaphragm (2) is situated in the state of suspense in which it is held by the energy of flow of the liquid against the counteracting force of the spring (3) loading the diaphragm (2). The diaphragm (2) is set in a housing (1) installed in the conduit system in such a way that the liquid on the upstream side of the diaphragm (2) flows through an annular space (6) radially around the diaphragm (2). The diaphragm (2) is especially suitable for installation in the housing (9) of a liquid filter.
