  • at tightened second connecting means of the first support body through the Shoulder surface of the screw shaft pressed against the first component so that in this area the fixing of the first support body to the first Component can be done by the second connection means.
  • the first support body facing shoulder surface of the second Supporting body can be easily formed by a sleeve, which is pushed onto the shaft of the screw.
  • the second is Support body loosely on the formed by the second connecting means Support on and is therefore movable in the direction of the first support body.
  • a spacer made of a soft elastic material between the second support body and the first support body or the first component may be arranged.
  • the Spacer is formed for example as a sleeve, which on the second Connecting means can be pushed. By gently squeezing the
  • spacers during assembly of the device may be the Resonance frequency of the system is set to a desired value become. In the case of the oil pan and the engine block can in this way the Resonance frequency can be set to a value at which the Internal combustion engine has as few vibrations.
  • the membrane preferably firmly connected to the first and second support body.
  • the Membrane may, for example, by vulcanization with the first and / or be glued to the second support body.
  • the tightness of the connection can be improved by in the region of a contact surface of the first support body to the first component a or a plurality of sealing lips are provided, for example, in one piece with the diaphragm are formed of elastomer. Such sealing lips can be arranged between the second support body and second component.
  • the second support body formed integrally with the second component.
  • the support body can formed for example by an angled portion of the component become.
  • the connection between the first and the second component predominantly through the thin membrane produced. Due to the small thickness of the membrane, this is permeable to Noise or electromagnetic fields. In certain cases it can Therefore, be advantageous if the device has a shielding, extending across the gap between the first support body and the second Extending support body away. Such a shielding device can at appropriate interpretation a poking out of noise or prevent electromagnetic vibrations.
  • Such a shielding device has in one possible embodiment Shielding on, inside or outside of the device at one of Support body is fixed.
