Definitions
- the invention relates to a closure cover for openings on containers, in particular on motor vehicle radiators, with an inner cover part which has at least one flow connection between the inside of the container and the outside of the container and a valve arrangement for releasing and blocking the flow connection, the valve arrangement moving a first and a second back and forth Movable valve body, wherein the first valve body is biased by a first spring in the direction of the container interior against a first sealing seat on the lid inner part and against a second sealing seat on the second valve body, and wherein the first valve body when a first limit value of the container internal pressure of the Inner lid part and when a second limit value of the inner container pressure of the inner lid part and the second valve body is released, in each case with the release of a flow connection between the inner container and the B
- the outer valve part can be lifted off, the second valve body being assigned a third sealing seat provided on the inner part of the cover, against which the second valve body comes to rest at a third limit value for the inner pressure of the container, which lies between the first and the second,
- Such a cover is known from DE 41 07 525 Cl.
- a valve cup with a flange running radially outward is used as the first valve body and a cylindrical sleeve concentrically surrounding the valve cup is used as the second valve body, which is also mine.
- one radially outward projecting flange is provided in the transition area to the cylindrical sleeve.
- the flange attached to it is shaped like a bead to form a bead.
- the valve pot which is acted upon by a compression spring in the direction of the interior of the container, is supported on the bead of the second valve body described by means of a sealing ring.
- the cylindrical sleeve which is also acted upon in this way in the direction of the interior of the container, is also mounted with its flange on a sealing seat of the inner lid part with the interposition of a sealing ring.
- Another sealing ring connected to the inner part of the cover lies opposite the flange of the cylindrical sleeve in the starting blocking position of the valve arrangement at a distance in the direction of the container exterior.
- the object of the present invention is to simplify the construction of such a closure cover.
- the task is for a cover for openings on containers, in particular on motor vehicle radiators, with a cover inner part which has at least one flow connection between the inside of the container and the outside of the container and a valve arrangement for releasing and blocking the flow connection, the valve arrangement having a first and a second rear and movable valve body, wherein the first valve body is biased by a first spring towards the interior of the container against a first sealing seat on the inner cover part and against a second sealing seat on the second valve body, and wherein the first valve body is exceeded when a first limit value of the internal container pressure of the inner lid part as well as when a second limit value of the container internal pressure can be lifted off from the inner cover part and the second valve body, in each case with the release of a flow connection between the container interior and the container exterior, the second valve body being assigned a third sealing seat provided on the inner cover part, against which the second valve body in one third, between the first and the second limit value for the container internal pressure comes into contact, whereby the previously existing flow connection between the container interior and the
- a further special embodiment of the invention is characterized in that the first and the third sealing seat are formed on the end faces facing away from one another of a hollow cylindrical sleeve which is connected to the inner cover part by a web.
- Another special embodiment of the invention is characterized in that the second sealing seat is arranged radially inside the first sealing seat.
- the flow paths in the event of overpressure in the interior of the container can be interrupted by a single ring seal which bears against both the first and the third sealing seat in the closing direction.
- Another particular embodiment of the invention is characterized in that the third sealing seat is arranged radially outside the second sealing seat. The function of the third sealing seat is independent of the first and the second sealing seat.
- the second sealing seat prevents overpressurized fuel from reaching the first sealing seat.
- a further special embodiment of the invention is characterized in that the second valve body comprises a valve cover with a substantially cylindrical shape, on the outer lateral surface of which a step is formed which serves as a stop for a seal which is fixed by a sealing ring which seals the Valve hood partially surrounds. This enables easy replacement of the seal.
- valve cover is guided axially displaceably on the hollow cylindrical sleeve. This ensures proper functioning of the valve arrangement according to the invention.
- Another special embodiment of the invention is characterized in that an annular gap is formed between the outer peripheral surface of the sealing ring and the inner cover part.
- the annular gap forms part of the flow path for the fuel pressurized.
- the invention generally provides the advantage that a cooling water circulation pump currently used in engines with a strong after-heating effect can be dispensed with. Such a pump circulates the coolant for some time after the engine is switched off. This prevents the coolant from "boiling up”.

- Another special embodiment of the invention is characterized in that an annular gap is formed between the outer lateral surface of the valve cover and the inner cover part. The annular gap forms a further part of the flow path for the fuel pressurized.
- FIG. 2 shows the closure cover from FIG. 1
- FIG. 3 shows the closure cover from FIG. 1 at a second limit value for an overpressure in the interior of the cooler
- FIG. 4 shows the closure cover from FIG. 1
- a closure cover 1 for a motor vehicle radiator comprises an outer cover part 3 provided with an actuating handle 2, on which an inner cover part 4 is held with a valve arrangement 4.
- the cover 1 In the position of use, the cover 1 is fixed to a radiator neck.
- the inner cover part 4 protrudes in the direction of the interior of the radiator into the radiator nozzle.
- An O-ring 6 seals the inner cover part 4 against the radiator nozzle wall.
- the valve arrangement 5 in the interior of the inner cover part 4 comprises a first valve body 7 and a second valve body 8.
- the first valve body 7 comprises a valve plate 9, on the side facing the cooler inside a seal 10 is attached.
- valve plate 9 is acted upon on its side facing away from the interior of the cooler by two closing springs 11 and 12 which are supported on a spring plate 13 with their ends facing away from the valve plate 9.
- the spring plate 13 in turn is supported on the inner cover part 4 or the outer cover part 3.
- the valve plate 9 is biased towards the cooler interior by means of the closing springs 11 and 12.
- the valve plate 9 Via the seal 10 designed as a flat sealing ring, the valve plate 9 is mounted on a first sealing seat 14 on the inner cover part 4 and on a second sealing seat 15 on the second valve body 8.
- the second valve body 8 is formed by a valve cover 16 and a sealing ring 17.
- the valve cover 16 has a substantially cylindrical shape.
- a step 18 is on the outer lateral surface of the valve cover 16 educated .
- the step 18 forms a stop for a ring seal 19.
- the ring seal 19 is fixed by the sealing ring 17 to the step 18 of the valve cover 16.
- the ring seal 19 interacts with a third sealing seat 20. In the valve position shown in Figure 1, the third sealing seat 20 is open.
- An arrow 21 indicates that fuel pressurized from the inside of the container via an annular gap between the inner lid part 4 and the outer circumferential surface of the sealing ring 17, between the third sealing seat 20 and the annular seal 19 can pass into an annular gap which can pass between the valve cover 16 and a sleeve 22 is formed.
- the sleeve 22 has the shape of a circular cylinder and serves to guide the valve cover 16 in the event of an axial displacement.
- the sleeve 22 is connected to the inner cover part 4 via a web 23.
- the valve cover 16 is biased away from the interior of the cooler by a compression spring 25.
- the end of the compression spring 25 facing away from the valve cover 16 is supported on a spring plate 26 which is fastened to the inner cover part 4.
- the valve cover 16 is pressed against the seal 10 of the first valve body 7.
- an opening 27 is recessed.
- the opening 27 in the valve plate 9 is closed on the side facing the interior of the cooler by a vacuum valve plate 28.
- Vacuum valve plate 28 is pressed against the valve plate 9 by a conical compression spring 29.
- the end of the conical compression spring 29 facing the interior of the cooler is supported on the valve cover 16 of the second valve body 8.
- the initial blocking position shown in FIG. 1 assumes the valve arrangement 5 when the internal cooler pressure moves between a negative pressure limit value and a first positive pressure limit value.
- valve arrangement 5 flows in cool content and fills all the free spaces upstream of the valve plate 9. In particular, cooler content flows past the third sealing seat 20, as indicated by the arrow 21.
- valve plate 9 If the cooler internal pressure exceeds a first overpressure limit value, the valve plate 9 is raised by the cooler contents against the action of the closing springs 11 and 12 from the first sealing seat 14 on the sleeve 22. The valve arrangement is then in the operating state according to FIG. 2, in which the cooler content reaches the cooler from the inside of the cooler, as indicated by arrow 30. In the meantime, the second sealing seat 15 is closed and the third sealing seat 20 is open.
- the second valve stage is formed by the valve cover 16 in connection with the valve plate 9 and the seal 10. If the excess pressure in the interior of the cooler continues to increase and finally exceeds a third limit value in the form of a safety limit value, the valve disk 9, together with the seal 10, lifts both from the first sealing seat 14 and from the second sealing seat 15. The resulting flow path is indicated in FIG. 4 by an arrow 32. Due to its inner diameter, the sealing support of the valve cover 16 forms an effective surface which corresponds to the required locking force of 2 + 0.2 bar. Since the ring seal 19 rests on the third sealing seat and is therefore limited in its axial movement, the valve plate 9 lifts off together with the seal 10 from the first sealing seat 14 and the second sealing seat 15 and the flow path 32 is opened.
- valve arrangement 5 changes from its operating state according to FIG. 4 to the previously explained operating states according to FIGS 3 over until it finally returns to its starting blocking position according to FIG. 1.
- the function of the vacuum valve plate 28 is ensured by a fourth sealing seat 24 which is formed in the vacuum valve plate 28 and interacts with the seal 10. This provides the advantage that the first (14), second (15) and fourth (24) sealing seat interact with a single seal (10).
