Definitions
- the present invention relates to a closure lid for openings on containers, in particular on motor vehicle radiators, according to the preamble of claim 1.
- an O-ring is held on the valve body in a radially open asymmetrical groove, which lies against the ring edge surface of the lid inner part designed as a sealing seat and thus seals a flow connection between the interior of the vessel and the exterior of the vessel. If the spring force, which presses the valve body against the sealing seat, is overcome at a certain upper limit value of the internal container pressure, the flow connection is opened. Since the area of the O-ring which is exposed from the asymmetrical radial annular groove lies directly in the venting flow, there is a risk that through direct flow pressure and / or through
- Inner cover part of a closure cover for a motor vehicle sensor with an overpressure / underpressure valve arrangement in a position after reaching a limit value of the interior container pressure according to a preferred embodiment of the present invention
- Figure 2 shows a section along the line II-II of Figure 1, but in the closed starting position and at pending internal pressure.
- the cover 11 shown in the drawing for example for a motor vehicle radiator, has, in a manner not shown, an outer cover part provided with an actuating handle, on which an inner cover part 14 is held with a vacuum / pressure valve arrangement 15.
- the closure cover 11 In the position of use, the closure cover 11 is fixed or screwed onto a radiator neck, not shown.
- the inner cover part 14 protrudes in the direction of the cooler interior in the cooler neck.
- An outer dashed-dotted O-ring 16 seals the inner cover part 14 against the radiator nozzle wall.
- the overpressure part of the valve arrangement 15 is designed in two stages and serves to prevent the cooler from boiling dry in a first overpressure stage and to ensure security against damage to the cooler system due to excessive overpressure in a second overpressure stage.
- the overpressure part of the valve arrangement 15 has a first valve body 17 and a second valve body 18 and a third valve body 19 in the interior of the cover inner part 14.
- the first valve body 17 is arranged above the second valve body 18 in the direction of the outside of the cover, while the third valve body 19 coaxially inside of the second valve body 18 is received.
- the first valve body 17 is designed in the manner of a valve disk standing upside down, on the side facing the cooler interior of which an annular seal 21 is provided which has an axially inwardly facing sealing surface.
- the first valve body 17 is acted upon from a side facing away from the interior of the cooler by a closing pressure spring 22, which is only indicated by dash-dotted lines and which is shown in another manner in FIG Way indirectly supported on the lid inner part 14.
- the first valve body 17 is biased in the direction of the interior of the cooler by means of the closing pressure spring 22.
- the first valve body 17 is seated on a first annular sealing seat 24 of the second valve body 18 via the seal 21 designed as a flat sealing ring.
- the one-piece second valve body 18 has a hood part 26, which is provided on its free face with the first sealing seat 24, and a concentric and hollow-cylindrical receiving part 27 for the third valve body 19 pointing from the bottom 28 of the hood part 26 to the interior of the radiator.
- the bottom 28 between the hood part 26 and receiving part 27 is provided on the outer circumferential side with a collar, the underside 29 of which forms a second sealing seat in relation to the inner cover part 14.
- this second sealing seat 28 Associated with this second sealing seat 28 is an internal O-ring 31 which is received in an annular groove 30 which is arranged in a collar edge 32 of the inner cover part 14 in such a way that it is open axially upward (facing the bottom 28 of the second valve body 18) ,
- the collar edge 32 is formed between a hollow-cylindrical upper region of the inner cover part 14 which receives the first valve body 17 and the hood part 26 of the second valve body 18 and a lower region of the inner cover part 14 which surrounds the receiving part 27 of the second valve body 18.
- the inner lid part 14 is provided with an axial opening 33 for flow connection to the interior of the container.
- the closing pressure spring 22 presses the first valve body 17 with its first ring seal 21 against the first sealing seat 24 of the second valve body 18, which in turn has its second sealing seat against the second ring seal (O-ring 31) on the inner cover part 14 is pressed.
- the axially upwardly open annular groove 30 in the collar edge 32 of the inner cover part 14 is provided with ventilation pockets 35, which are formed by slots 36 extending from the larger inner edge of the annular groove 30.
- the slots 36 run over the entire axial depth of the annular groove 30.
- the slots 36 or ventilation pockets are arranged in a plurality (here 16) evenly distributed over the circumference of the annular groove 30 (FIG. 2).
- FIG. 1 shows a flow connection 40 made from the inside of the container to the outside of the container between the inner edge of the collar edge 32 and the lower inner part of the cover and between the second sealing seat 28 and the O-ring 31 when the second valve body 18 is lifted off the O-ring 31 -Rings 31 in the annular groove 30 when the vent path 40 is closed, ie in a position in which the second valve body 18 rests with its second sealing seat 28 on the 0-ring 31 in the inner cover part 14 under the action of the closing pressure spring 22.
- the O-ring 31 is compressed by the arrangement of the ventilation pockets 35 and in the region of these ventilation pockets in a radially undulating manner.
- the first valve body 17 sits on the second valve body 18 (corresponding to FIG. 1) and the second valve body 18 differently than shown in FIG. 1 on the inner cover part 14 or on the O-ring. 31. If a first limit value of the container internal pressure is exceeded, the first valve body 17 is raised against its closing pressure spring 22, since there is a connection between the container interior and the underside of the first valve body 17 past the tightly closing third valve body 19 and through the second valve body 18. By opening a first flow connection, air can flow outward from the air cushion located above the liquid coolant and thereby compensate or reduce the excess pressure. The second valve body 18 remains pressed against the collar edge 32 of the inner cover part 14.
- the first valve body 17 again comes into sealing contact with the second valve body 18.
- the internal pressure of the container continues to increase even during or after the air cushion has escaped, this leads to liquid coolant the underside of the second and third valve bodies 18 and 19 arrives, in the manner explained in the above-mentioned prior art there is a dynamic pressure which leads to an axial movement of the third valve body 19 against its third compression spring 43; the first-mentioned flow connection is closed by this sealing movement of the third valve body 19.
- a reduction in the pressure again leads to a return movement of the third valve body 19 and the opening of this connecting path after the first-mentioned flow connection is closed again.
- FIG. 1 also shows a vacuum valve body 57 within the first pressure valve body 17.
- the number of ventilation pockets shown in FIG. 2 can also be smaller or larger, and that the ventilation pockets can also be arranged in an irregular arrangement along the circumference of the annular groove.
- the ventilation pockets are formed by tapered or stepped slots.
