An apparatus handles at least one fluid in a vehicle, particularly an at least partly electric driven vehicle, comprising at least one essentially plate-shaped formed first distribution element and at least one second distribution element arranged essentially parallel to the first distribution element. The first distribution element and/or the second distribution element include at least one fluid handling element. The first distribution element and the second distribution element include plastics.

The present invention relates to: a device () for separating off liquid and/or particulate contaminants from a gas flow (), in which a flow path of the gas flow () runs between at least one first electrode () acting as a counter electrode and at least one second electrode () acting as an emitter electrode and having an electrode end () oriented in the direction of the first electrode, and a direct-current voltage exceeding the breakdown voltage can be applied between the first electrode () and the second electrode () in order to form a stable low-energy plasma (), wherein the second electrode () extends substantially along a first axis (X) in a first direction and the first electrode () has at least one plateau region () which is arranged opposite the second electrode () and which extends at least regionally in a first plane running substantially perpendicular to the first direction (X); and a method for operating such a device.

Device and method for separating off contaminants

In the drive train of a combustion engine an auxiliary arrangement is arranged which is to be coupled with an axial flow machine including a stator and a rotor, in order to perform an actuating movement. The stator has a coil arrangement, and the rotor has an essentially cup-shaped support for permanent magnet elements. The coil arrangement of the stator has at least one cylindrical winding and is at least partially enclosed by two essentially pot-shaped magnetic flux yokes. Each of the pot-shaped magnetic flux yokes has side areas with magnetic flux poles whose outsides are oriented towards the permanent magnet elements of the rotor. The magnetic flux poles of the stator are arranged spaced apart from the permanent magnet elements of the rotor. The magnetic orientation of neighboring permanent magnet elements towards the air gap alternates.

An apparatus for sonic coupling between an intake tract or engine compartment and a vehicle interior of a motor vehicle has a housing into which sound enters from the intake tract via a first line, and out of which sound exits into the vehicle interior via a second line. A transmission body is arranged in the housing, the transmission body having a gas-tight separating wall between a sound inlet into the housing and a sound outlet out of the housing. The position of the separating wall is held essentially constant by a positioning device. A transmission wall between the separating wall and the housing provides an acoutis transfer function that is adjustable. The separating wall runs generally perpendicular to the longitudinal axis of sound propagation and the transmission wall runs at an angle &#x3b1; to the longitudinal axis of sound propagation.

Sonic coupling between an intake tract or engine compartment and the interior of a motor vehicle

A fluid guideline with at least two structural elements made of substantially soundproof material has at least one opening for sound damping. An impedance change (in particular in the form of an impedance discontinuity) of the flow resistance of the fluid flowing through the fluid guideline is present between two adjacent structural elements, and the at least one opening is arranged in the region of the impedance change between two adjacent structural elements.

The invention relates to a silencer ( ) for noise-laden gas pipes, especially for a suction pipe and/or an exhaust pipe of an internal combustion engine, comprising an outer pipe ( ) with an inlet side ( ) and an outlet side ( ), a plurality of diaphragm rings ( ) each with an outer surface connected ( ) to the inner surface of the outer pipe ( ), at least one insert ( ) with an outer surface connected ( ) to the inner surface of the outer pipe ( ) and/or the diaphragm rings ( ) and with a plurality of openings ( ) which are closed on one side. Said insert ( ) forms sub-pipes for the gas flow in the silencer, and the openings ( ), which are closed on one side, open into the sub-pipes, the depth thereof being /4 in relation to the wavelength of a frequency to be silenced. At least one perforated wall ( ), extends between at least two diaphragm rings ( ) whereby an outer surface is connected ( ) to at least one inner surface of the two diaphragm rings ( , wherein at least one resonance cell is fixed between the two diaphragm rings ( ) of the perforated wall ( ) and the outer pipe ( ).

A power unit bearing, in particular for motor vehicles, is characterized by mechanically integrally joining a conventional bearing, in particular a hydraulic bearing, to a connectable or disengageable hydraulic switching module for the purpose of matching the power unit characteristics to changing operational conditions of this power unit. The switching module is inserted between a chassis-side base plate of the conventional bearing body and a chassis-side adapter of the power unit bearing.

The broadband surface-like absorber of the invention is used, in particular, for absorbing troublesome airborne noise in the acoustic frequency range. The broadband surface-like absorber, which operates on the Helmholtz resonator principle, is distinguished by a checkerwork of irregular construction, the webs of which are aligned with their narrow sides perpendicular to the principal surface of the perforated plate and the side edges of which are connected in a sound-pressure-resistant and fluidtight manner on the sound side to the rear side of the perforated plate and, on the rear side, to an extended-area cavity boundary aligned with the same orientation as the perforated plate to form differently tuned chamber resonators.

Sound absorber for sound waves

The invention relates to a directly hydraulically damping broadband damper designed as a sequence of Helmholtz resonators with elastomer/gas springs to damp pressure pulses in pressurized liquids and in the audible range frequencies, in particular in hydraulic servo systems.
