The invention relates to a valve having a movably arranged valve body for selectively opening and closing a valve passage, with a sealing element, for example a lip seal, being arranged on the valve body in such a way that the sealing element comes to bear against a valve seat if the valve body is moved in a closing direction, and with at least one outer peripheral section of the sealing element being resiliently movable or elastically and/or flexibly deformable substantially in the movement direction of the valve body, and with a protective collar being arranged radially outside the outer peripheral section of the sealing element, which protective collar is fixed to the valve body in order to protect the sealing element from damage and/or from excessive deformation.

The invention relates to a relief valve comprising:

Relief valve with double valve arrangment for releasing a booster pressure of a turbocharger

The invention relates to a gas conducting device for internal combustion engines, notably motor vehicle engines, comprising a pressure line ( ), a fresh-gas line ( ) supplying fresh gas, a discharge line ( ) and an orifice ( ) which opens into the fresh gas line ( ) and the discharge line ( ). At least the pressure line ( ) and the orifice ( ) are connected via a control element ( ) for the metered addition of gas. A compensating unit ( A; A; ) is provided for so as to compensate forces which act on the control element ( ) as a result of a pressure difference (p -p ; p -p ) between the gas pressure on the compressed gas side (p ; p ) and the fresh gas side (p ; p ).
