  • the invention relates to a throttle gap seal according to the preamble of the claim 1 for valves that control the flow of gaseous media in internal combustion engines control cyclically (i.e., per work cycle) and in closed mode State show very low leakage rates.
  • the invention proposes a throttle gap seal according to the features of claim 1 before.
  • the throttle gap seal according to the invention thus has an insert, the is received in the housing. This is to the housing with at least one Seal sealed.
  • the insert comprises the flow cross section of the Housing and can, in the closed state of the valve, with his the actuator of the valve facing sealing surface on the position of the actuator with the insert facing sealing surface at least once align in the housing.
  • the sealing surface of the insert and the sealing surface of the actuator without continuous force on each other in the closed Position of the valve opposite. Insert and actuator are thus powerless compared.
  • the actuator takes its rest-closed position without a stop against the insert and housing.
  • a stop By dispensing with a stop can avoid extreme acceleration peaks of the moving parts.
  • the seal preferably takes on additional weight in addition to the medium seal Functions, such as the thermal insulation between housing and insert and / or the attachment of the insert in the housing.
  • This case of thermal Isolation concerns in particular the static aspect.
  • the thermal insulation between the housing and insert represents in particular in the event that the valve is located in the area of a cylinder head, sure that the Heating the housing does not transfer to the insert, and thus a caused high temperature difference between the actuator and insert.
  • the actuator and the insert part a similar quotient of medium washed component surfaces / heat capacity of the component, to a similar timing behavior to achieve the thermal expansion of the components.
  • This training of actuator and insert considered in particular effects due to strong intake air heating in turbocharged engines.
  • the actuator of one or consists of several individual components, some of one or more materials low density, such as light metal, metal foam, plastic foam, fiber reinforced plastic are made.
  • the insert can be in the closed state of Valve with its the actuator facing sealing surface at least once to the position of the actuator with the insert facing the sealing surface align in the housing.
  • the throttle sealing gap between the actuator and insert by positioning the insert in the plane or in addition is adjustable perpendicular to the plane. This positioning can be done by mechanical (for example, distance gauge), optical (for example, light gap measurement) or calibrate hydraulic (for example gap flow) the throttle sealing gap are made.
  • the calibration of the throttle sealing gap can also by self-centering of the insert on the actuator respectively. This is preferably done by applying the sealing surface of Valve on the sealing surface of the insert, wherein one of these surfaces with a thick coating is provided, which the throttle gap in the assembled state at least partially closes and in the later operation of the valve at the opposite, wear-resistant sealing surface removes.
  • aligning the insert in the housing results the throttle sealing gap by automatically returning the alignment of the Insert on the actuator in the rest-closed position. This will be for example by a decreasing throttle gap height in the direction of the rest-closing position reached.
  • the insert closes movable, but medium-tight via seals to the housing and it are the sealing surfaces of insert and actuator provided with a wear-resistant surface coating.
  • valve 16 has a housing 1 for guiding the gaseous medium in the valve 16.
  • a housing 1 for guiding the gaseous medium in the valve 16.
  • the housing 1 is a movable drivable, about the axis of rotation 24 pivotable actuator 4 to change the corresponding flow cross section 11 provided in the valve.
  • an insert 2 is added in the Housing 1, which is the housing 1 with a seal 3 sealed.
  • the insert part 2 comprises the flow cross-section 11 of the housing 1.
  • the actuator 4 is shown in its closed position.
