Definitions

  • the invention relates to a radiator neck with a closure cap according to the preamble of claim 1, which corresponds to an unpublished, internal prior art of the applicant.
  • the complete pressure relief valve that is to say its closure member and its valve seat
  • the vacuum valve As a result, both the pressure relief valve and the vacuum valve can be completely assembled, checked and adjusted as necessary at the factory. So that the cooling liquid or vapor formed from it cannot escape past the sealing cap between the latter and the radiator socket when the sealing cap is in place, the sealing cap must be sealed at a suitable point with respect to the radiator socket.
  • the second seal can, for example, rest against the free end of the radiator neck, wherein it is assigned to the inner surface of a closure cap of the closure cover. In this case it is a flat gasket.
  • the inner seal is an O-ring held on the closure cover.
  • a second O-ring can be attached to the cover. Theoretically, it is even conceivable to provide the flat gasket mentioned in addition to these two O-rings. At least in the normal case, the latter is of no importance with regard to a perfect seal. It is only effective if the middle of these three seals fails.
  • the closure cap according to this internal prior art is held on the radiator neck by means of a threaded connection, wherein it has a cylindrical projection provided with a bolt thread, while the radiator neck is equipped with a corresponding nut thread.
  • the O-ring or the O-rings are located further inside in the socket with regard to this thread.
  • the radial outlet opening is not provided on the radiator neck, but on the cover.
  • the object of the invention is therefore to develop a radiator neck with a cap of the type described in such a way that the cap is attached to the neck despite maintaining an integrated overpressure and vacuum valve and thereby a screw connection of the radiator neck and the cap can be dispensed with.
  • the radiator neck with a closure cover is designed in accordance with the preamble of claim 1 in accordance with the characterizing part of this claim.
  • at least the inner one is an O-ring.
  • This bears against the assigned radiator socket wall with radial pressure, which is particularly strong when the radiator system is under pressure.
  • this cap can only with overpressure and even after releasing the overpressure a corresponding effort or be removed from the radiator neck.
  • this axial force is applied when the closure cover is unscrewed. A corresponding axial force does not occur with a conventional bayonet lock. Rather, it must be applied by pulling the closure lid accordingly. This can be associated with a corresponding tilt and lead to damage to the O-ring.
  • a bayonet lock is now possible in that, according to the invention, there is also a lifting counter-curve which, in cooperation with the counter-cam, forms a lifting device for the locking cover, which pushes the locking cover so far outwards during the opening-rotary movement until the inner O-ring has come free of its wall or, in the case of a conical wall, the pressure on it has been overcome.
  • a bayonet lock has the advantage over a rotary lock that the closed rotary end position can be found safely due to the existing rotary stops, which is not guaranteed with a screw-on cover.
  • the bayonet cam in or Remove the axial direction by the amount of the bayonet curve slope and the corresponding angle of rotation.
  • the counter cam and the bayonet cam and thus the entire cover in the stroke opening direction, are finally raised via the inner stroke section of the stroke counter curve.
  • the inner stroke section is now dimensioned such that it lifts the closure lid until the first inner O-ring comes free from its wall.
  • the overpressure in the cooler system can be reduced to the outside in the form of a bypass past the closure cover. This corresponds to the known pre-locking position.
  • the counter cam After a further rotary movement, the counter cam finally reaches the outer stroke section of the stroke counter curve. At the latest at its outer end, an optional second O-ring is then at least released from the cylinder wall to such an extent that the cover can be removed without any particular effort.
  • each bayonet curve and each counter stroke curve form an outer groove running in the circumferential direction of the nozzle, which is open in the radial direction of the nozzle to the outside and opens axially outwards at the free nozzle end, the Width of this mouth, seen in the circumferential direction of the neck opening, corresponds at least to the length of the bayonet cams and counter-lifting cams.
  • the bayonet cam is inserted with the lifting counter-cam when the closure cover is placed in the outer groove, the axial movement then being followed by this axial movement when the closure cover is to be attached to the connecting piece. The weight loss takes place in the opposite direction.
  • the bayonet nock encompasses the nozzle part which has the bayonet curve in exactly the same way as is known from the conventional radiator cap made of sheet metal, from above and from the outside inwards in relation to the mentioned external groove of the radiator nozzle.
  • Another variant of the invention is characterized by the features of claim 3.
  • the cover 1 and the radiator neck 2 are connected to each other by means of a bayonet lock.
  • the cover 1 is placed on the radiator neck 2 in the mounting direction 3 until the bayonet cams 4 lie below the start edge of the respectively assigned bayonet curve 5, so that subsequently turning in the direction of arrow 6, that is to say in the closing direction of rotation, is possible.
  • Each bayonet cam 4 then slides in a known manner along the bayonet curve 5, which descends downwards, which leads to a lowering movement of the closure cover 1 superimposed on the rotary movement.
  • the latter bears a sealing ring 7 designed as an O-ring 7 at its front end in the direction of attachment 3. As shown in FIG. 5, for example, it lies against a cylindrical inner surface 8 and seals, at least when the bayonet is completely closed thus at this point the gap 9 between the sealing cap 1 and the radiator neck 2.
  • each of the two bayonet curves 5 of the exemplary embodiments initially runs approximately in a plane perpendicular to the geometrical axis 10 of the radiator connector 2 or at most slightly inclined thereto, when the closure cover is screwed in. This is then followed by the inclined or steeper section, which causes the closing cover 1 to be pulled in in the direction of the arrow 3. The so-called pre-locking position is reached at the transition between these two curve sections (FIG. 4).
  • the inner sealing ring which, in the case of two O-rings, does not yet form a first inner O-ring 7 on the cylinder inner surface 8.
  • the closure cover is opened completely in the opposite direction to arrow 6 and then raised in the opposite direction to arrow 3 from the radiator neck 2.
  • the turning in the direction of arrow 6 takes place until the front edge 15 of the bayonet cam 4 in the closing direction of rotation bears against the assigned rotary end stop 16 of the radiator connector 2.
  • a second O-ring 17 is also provided. It is already in place when the closure cap 1 is plugged onto the upper end of the radiator connector 2 against the additional bore part 14 of the radiator connector 2 with a diameter. As a result, in the pre-locking position (FIG.
  • a third sealing ring 19 is provided, which is designed in a known manner as a flat gasket ring and rests on the bead-like opening of the radiator connector 2 when the bayonets are completely closed or is pressed thereon in a sealing manner. In the pre-locking position, this seal is of course relieved or lifted from the mouth opening.
  • a conically tapering from the outside in can also be provided, the cone then having to be chosen such that in the case of two O-rings the second O-ring 17 also bears against the radiator socket wall 2 in the pre-locking position.
  • the O-ring grooves are designated 21 and 22.
  • each outer groove which runs in the circumferential direction of the connecting piece.
  • the bottom of the groove can be seen in FIG. 1.
  • each outer groove opens at the free radiator nozzle end, the groove mouth being designated 25 in FIG. 1. Its length measured in the circumferential direction corresponds to the length of the bayonet cam 4.
  • Each bayonet cam 4 is connected to a counter cam 26, in particular directly, or is produced in one piece in the case of plastic production.
  • the counter cam 26 is then formed by the surface or edge of the assigned bayonet cam 4 pointing in the mounting direction 3 of the closure cover 1. Seen in the closed direction of rotation 6, this counter cam 26 drops towards the rear, as shown in FIG. 1 of the drawing. This creates at this point a sliding bevel 27 which is of importance when opening the closure cover 1 in the manner explained below.
  • the height of the bayonet cams 4 and counter cams 26 together is measured in the axial direction so that the two are not greater than the width of the outer groove 24 measured in the axial direction at the narrowest point, although the bayonet engagement at the start of the closing rotary movement is not taken into account is left.
  • each bayonet of the bayonet closure is closed in a known manner, the bayonet cam 4 interacting with its assigned bayonet curve 5. Due to the strong friction between the one or more O-rings and the associated wall of the radiator connector 2, the closure cover 1 would remain in its lowest position when viewed in the axial direction when the bayonets were opened.
  • the bayonet surfaces and cam surfaces which are effective when plugged in are not able to exert a pulling action against the arrow 3 on the closure cover 1. This is also the reason why so far there is no known closure cover which is held on a radiator socket by means of a bayonet closure and is sealed against the radiator socket by means of O-rings.
  • each counter cam 26 is first moved along the flat or approximately flat section 28 of the stroke counter curve 23.
  • the bayonet cam 4 then continuously moves away from the part of the inner bayonet curve that drops in the rotational closing direction.
  • the closure cover 1 does not yet perform any lifting opening movement, or at least not yet complete it.
  • the closure cover is provided with a centering pin 32 which carries the first inner O-ring 7 in the region of its free end and which at the same time forms the housing for a pressure relief valve.
  • It is preferably made of plastic, as is the lid upper part 33 with the integrally formed bayonet cams 4 and counter cams 26. Both are, as shown for example in FIG. 4, connected to one another via a centering and firmly held together in a known manner.
  • Each O-ring groove is molded on.
  • the same preferably also applies to the valve seat 34 of the pressure relief valve 35 and at least one radial outlet opening 36 on the outflow side of the valve housing wall, via which che with the pressure relief valve open, the medium can pass into the gap 37 between the centering pin 32 or valve housing and the radiator nozzle. From there, it arrives in the manner described, even when the radiator cap 1 is firmly closed, via the radial outlet opening 12 of the radiator connector 2.
  • the closure member of the pressure relief valve 35 is designated 38 (FIG. 4) and is designed in a known manner. It is spring-loaded by means of a helical compression spring 39.
  • the vacuum valve 40 is arranged centrally for this purpose.
  • its closure member 42 which is loaded by the spring 41, bears against the common sealing ring 43, which at the same time forms the valve seat of the vacuum valve 40.
  • the closure member 38 of the pressure relief valve 35 is raised in a known manner, while in the event of negative pressure the closure member 42 of the vacuum relief valve 40 is shifted downward, in each case against the resistance of the loading spring 39 or 41.
  • the part 44 of the radiator connector 2 which has the stroke-counter curves 23 is located on a compensating tank 45, but at least on an upper part of such a compensating tank.
  • a so-called expansion tank is provided in addition to the cooler, which carries the sealing cover and into which both the cooling water and cooling water additives are poured.
  • radiator neck can also be formed in two parts and while the inner part of the radiator neck forms the radiator neck part 44 with the stroke opposing curves 23, the bayonet curves 5 are located on a separately produced outer radiator neck part 46 or 47.
  • the inner part 44 of the radiator neck does not necessarily have to be connected to an expansion tank or be part of the same, but that it can also be the tubular attachment of a radiator upper part or radiator water tank.
  • the inner part 44 of the connector 2 is made of plastic, as well as the plastic production of the entire cover 1 (with the exception of the springs) is preferred.
  • Polypropylene is preferably used for the expansion tank, while the lid is expediently made from polyamide, a highly heat-resistant variant having to be used and glass fiber reinforcement or the like also being provided.
  • the two O-rings 7 and 17 lie firmly against the radiator socket wall and you want to open the closure cap 1, this means that the two O-rings are under a heavy load Friction seen in the circumferential direction of rotation.
  • the part of the sealing cap 1, which carries the two O-rings 7 and 17, can be rotatably supported on the remaining part of the sealing cap 1, in particular on the upper part carrying the bayonet cams 4, in a manner not shown .
  • the medium flowing off under pressure enters the pressure relief valve (35) via at least one opening (44) at the free inner end of the radiator connector (2).
  • Each bayonet cam and its associated counter-cam form a movable element along the outer groove of the radiator neck, which is why this outer groove, measured in the axial direction, must be at least as high at every point that the movement of this element is not hindered when the closure cap is attached and when it is released.
  • the bayonet curve also has the otherwise usual task here, namely when closing the closure cover to pull it against the neck opening (arrow direction 3 in FIG. 1) in such a way that a seal which may be located between the neck opening and a rim of the cover is pressed.
  • an at least partially inclined bayonet curve is necessary in order to achieve the desired sealing between the sealing cover and the radiator nozzle.
  • the bayonet curve does not have to extend inclined over its entire length to the neck opening or a plane perpendicular to the longitudinal axis of the neck, rather it is sufficient if only a part of it has such an inclination.
  • this is the last section that extends up to the rotary end stop 16.
  • the section of the bayonet curve first reached by the slot mouth 25 runs approximately parallel to the mouth plane in FIG. 1.
  • the starting area of this section is opposite the second flat section 30 of the stroke counter-curve 23, which merges smoothly into the outer stroke section 31.
  • the two flat sections 28 and 30 of this embodiment lie at different levels in the axial direction of the nozzle.
  • the second flat section 30 of the stroke counter-curve 23 lies axially opposite an auxiliary cam 57 pointing into the interior of the socket.
  • Such an auxiliary cam 57 is provided on each bayonet curve 5. It is particularly important when opening the closure lid. When the closure cap 1, which is usually under high pressure, is opened, the inner lifting section 29 releases the first O-ring 27 and thus connects the interior of the socket or the cooler to the outside atmosphere. In this way the overpressure can be released. This process can take a certain amount of time, especially in the case of very high overpressure and a small cross-section.
  • the auxiliary cam 57 mentioned is present in the exemplary embodiment according to FIG. 7.
  • the counter cam 26 After reaching the pre-locking position with overpressure reduction, the counter cam 26 abuts the auxiliary cam 57, thereby preventing rapid further rotation in the direction of arrow 58.
  • the auxiliary cams 57 In order to bring this cover into a rotational position suitable for removal, the auxiliary cams 57 must be overcome. This means that the sealing cover must again make a lowering movement towards the cooler. This is not possible, or at least not readily possible, in the case of excess pressure in the radiator neck.
  • the user is therefore prevented from "turning" the closure lid quickly in the opening direction 58 and the inattentive user is made aware by the auxiliary cams 57 that he does not turn the lid too quickly, but first waits for the excess pressure to be released.
  • the second flat section 30 of the reciprocating cam 23 is lowered in the manner described.
  • This sliding edge of the auxiliary cam 57 is designated 59 and the falling edge 60.
  • the oblique edge 61 in FIG. 7 has turned out to be relatively short, in relation to the exemplary embodiment according to FIG. 1, for example. Similar to FIG. 1, the oblique edge 61 of the bayonet curve 5 is followed by an approximately flat section 62, which extends to the auxiliary cam 57, the latter then merging into the slot mouth 25.
  • a rear bevel 63 is particularly important, which is located at the rear end in the opening direction 58 of the counter cam 26 or this element. It preferably runs approximately parallel to the sliding counter bevel 27 of the counter cam 26 (FIG. 8).
