Definitions

  • the present invention relates to a closure cover for openings on containers, in particular on motor vehicle radiators, according to the preamble of claim 1.
  • the first and the second valve body are nested concentrically with each other, wherein the second valve body axially between two end positions, which are bounded by a sealing seat or an axially opposite sealing surface of the inner lid part can be moved and wherein at rest, the first valve body is spring-loaded on the lid inner part supporting the second valve body.
  • the sealing surface of the second valve body which is supported on the sealing seat of the cover inner part, lies radially on the outside relative to that sealing seat of the second valve body against which the sealing surface of the first valve body is supported.
  • the second valve stage which is represented by the first valve body, concerns the Safety function of the closure cap to the effect that upon further increase of the container internal pressure with the exceeding of a safety limit of the first valve body is lifted from the second valve body, so that opens a second flow connection from the container interior to the container exterior.
  • a closure lid of the type mentioned in which at rest, the first valve body to a sealing seat of the inner lid part directly abuts and the second valve body, the rest of a first compression spring of the first valve body against a second Compressive spring is pressed in the first valve stage after exceeding the first limit value of the container internal pressure when reaching the second limit against a further axially opposing sealing seat on the inner lid part is pressed, the first valve body lifts from its sealing seat on the inner lid.
  • the first flow connection is thereby given between the two valve seats on the inner side of the cover on the one hand and the first and second valve body on the other hand and initially closed by the first valve body and then by the second valve body.
  • the first valve body When the safety overpressure is exceeded, the first valve body is axially raised by a vacuum valve body which is acted upon in this way, which axially lifts the second flow connection by lifting it off from the second valve body creates.
  • the tolerant structural adaptation of the individual components is less critical here, however, the design of the inner cover part is somewhat more expensive.
  • Object of the present invention is to provide a closure cover of the type mentioned, which is simplified in terms of manufacturing technology and assembly technology with improved hysteresis.
  • the inventive measures it is achieved that the production of the individual components and the adaptation to each other is less tolerance-bound and that the assembly can be done faster.
  • the hysteresis behavior is improved due to the throttle gap arranged in front of the seal.
  • the closing of the flow communication between the second and third valve bodies is achieved primarily by the presence of liquid coolant and not by the increased gas pressure. In other words, when increasing the container internal pressure, the air cushion located above the liquid coolant can flow out and contribute to a pressure equalization until it is degraded and the liquid cooling medium is present.
  • a closure lid with a safety lock for openings on containers is also known.
  • This safety lock makes it possible to prevent unscrewing of the closure lid when prevailing in the container overpressure, in that the closure cap is blocked against the filler neck on the container non-rotatably.
  • This known safety lock uses an axially movable insert which surrounds the inner cover part or its valve arrangement and which is thereby exposed directly to the pressure prevailing in the container overpressure by its inner bottom is disposed in the opening of the filler neck.
  • This axially movable insert is axially movable in a tubular additional inner part, but held non-rotatably, which sits non-rotatably in the filler neck of the container and against which the closure lid is rotatable. When occurring in the container overpressure, the insert is moved axially in the direction of the closure lid and engages in this non-rotatably. This results in a rotational blocking of the closure lid over the insert and the additional inner part with the filler neck of the container.
  • both the axially movable insert and the tubular additional inner part increase the diameter of the Cover inner part of the closure cover or reduce the effective area of the valve assembly of the closure cap, which has a negative impact on the response of the valve assembly.
  • a guide element is provided for direct transmission of motion from the first valve body to the coupling insert according to the features of claim 17.

  • the anti-rotation lock is still activated.
  • the said overpressure can be reduced via the second flow connection, after which a corresponding return of the valve bodies via the various operating states can take place through the individual compression springs and the clutch insert 180, as FIG. 5 shows.

  • the vehicle If the vehicle is shut down, for example, after a long journey, an increase in pressure may result inside the radiator, as a result of which the radiator content (air or water or water vapor) can flow to the valve arrangement 115. If the coolant volume expands as a result of this reheating effect in such a way that the container volume is exceeded, this would inevitably lead to coolant discharge.
  • the vacuum valve body 157 is lifted with its sealing seat 161 from the underside of the radially inner sealing edge 167 of the first ring seal 121 of the first valve body 117 toward the interior of the cooler , The lowering of the vacuum valve body 157 takes place against the biasing force of the third compression spring 159, so that opens in a manner not shown, a flow communication path between the radiator interior and the radiator outer.
  • the sealing seat 61 or 161 of the vacuum valve body 57, 157 is not arranged on a in the chamber 34, 134 flat plate, but arranged in a cylindrical chamber 34, 134 to the outer periphery in the Cross-section sawtooth plate provided.
