Definitions

  • the invention relates to a closure lid for the filling opening of a coolant container in automotive cooling systems
  • a lid housing engaging in the filling opening with a channel connecting the container space to be sealed with the outside air and a valve for shutting off the same with a valve membrane, which has a sealing surface under the force of a spring acting in the direction of the channel axis and supported on a surface fixed to the housing rests against a valve seat surrounding the channel and can be lifted off from it by the overpressure in the container space against the spring force.
  • a closure lid for the filling opening of a coolant container in automotive cooling systems
  • a lid housing engaging in the filling opening with a channel connecting the container space to be sealed with the outside air and a valve for shutting off the same with a valve membrane, which has a sealing surface under the force of a spring acting in the direction of the channel axis and supported on a surface fixed to the housing rests against a valve seat surrounding the channel and can be lifted off from it by the overpressure in the container space against the
  • the pressure value is set at which the valve opens in order to reduce an excess pressure prevailing in the cooling system to a predetermined value and thus prevent the radiator from bursting as a result of excess pressure.
  • a coolant pump that circulates the coolant in the cooling system is also put into operation, which creates a pressure difference between the suction side and the pressure side of the coolant pump within the cooling system.
  • the internal pressure of the cooler is reduced by a certain amount. The pressure difference that has to be overcome increases by exactly this amount until the safety valve in the sealing cap opens as a result of the excess pressure.
  • the coolant heats up, which increases the pressure in the cooling system. Due to the increased pressure difference on the suction side of the coolant pump, in the vicinity of which the closure cap is also located, the pressure can rise to a value which is above the opening pressure or pressure threshold value at which the valve in the closure cap would open when the coolant pump is at a standstill. If the engine is switched off in this state and the coolant pump is also shut down, there is no immediate pressure reduction on the suction side of the coolant pump. The pressure in the cooling system is above the opening pressure of the valve of the closure cover, so that it opens suddenly. This can result not only in loss of coolant, but also in injuries to people due to sudden escaping hot coolant or coolant vapor.
  • the invention has for its object to provide a cover of the type mentioned, in which the pressure difference until the opening pressure of the valve of the cover is reached regardless of whether the coolant pump is working or not.
  • valve seat is formed on a sleeve which is axially adjustable in the cover housing against the force of the spring and which, with an at least approximately axially normal surface facing away from the spring, adjoins a pressure chamber which, in the closed position of the closure cover, is opposite the Outside air and the container space closed and can be connected to the suction side of a coolant pump circulating the coolant in the cooling system.
  • the coolant pump when the coolant pump is operating, a negative pressure is generated in the pressure chamber compared to the state when the coolant pump is at a standstill, as a result of which the sleeve is adjusted in the direction of the valve spring acting on the valve membrane. Since the valve spring relaxes in the process, it now opens at a lower overpressure - in absolute terms. Due to the adjustable travel of the sleeve, the change in the opening pressure or threshold value can be selected so that it corresponds to the pressure reduction caused by switching on the coolant pump on the suction side thereof. If the coolant pump is switched off, the outlet pressure prevails again in the pressure chamber.
  • the sleeve carrying the valve seat and thus also the valve spring are again adjusted to their starting position corresponding to the stationary coolant pump.
  • the valve is thus opened both when the drive machine is at a standstill and when it is running, regardless of the pressure change caused by the coolant pump, in each case with the same pressure increase in the coolant tank. A sudden opening of the valve after switching off the coolant pump can no longer occur.
  • the guidance of the sleeve in the lid housing must be designed so that no pressure equalization between the interior of the container and the outside air can take place between the sleeve and the surrounding housing section. This can be achieved in a simple and effective manner in that a sealing membrane which enables the movement of the sleeve is arranged between the sleeve and the housing section surrounding it.
  • the sealing of the pressure chamber can be achieved in a structurally simple manner in that the pressure chamber is designed as an annular space surrounding the sleeve, which is at least partially enclosed by a bellows which can be expanded against the spring force. As a result, it is not necessary to seal parts that can be moved relative to one another.
  • the pressure chamber can be connected to the suction side of the coolant pump in a simple manner in that the pressure chamber has a connection opening that is open to the peripheral surface of the cover housing and that sealing rings are arranged axially on both sides of the cover housing on the peripheral surface, which seal seals against the filling opening Wall are determined, a connection channel which can be connected to the suction side of the coolant pump opening on this wall. If the cover is thus inserted into the filling opening, the connection between the suction side of the coolant pump and the pressure chamber is automatically established.
  • the closure cover When the closure cover is designed as a screw cover, it is expedient if the cover consists of a first housing part provided with an externally threaded connection and a second housing part which is freely rotatably connected to the latter and which receives the valve and carries the sealing rings. If this sealing cap is inserted into the filling opening, the first housing part can be screwed in without the second housing part carrying the sealing rings being rotated. It is only moved axially when the first housing part is screwed in.
  • 10 denotes an expansion tank of a motor vehicle radiator, in the filler neck 12 of which a screw cap generally designated 14 is screwed.
  • This comprises a first cover part 16 with a handle part 18 and an external thread connector 20 which is screwed into an internal thread section 22 of the filling opening 12.
  • a second cover part 24 is connected to the first cover part 16.
  • This has an essentially tubular housing 26, which is provided at its end facing the first cover part 16 with an annular extension 28 which engages in a tubular extension 30 of the first cover part 16 and with a radially outwardly directed ring claw 32 a radially after internally directed annular claw 34 of the tubular extension 30 engages behind, the extension 28 being able to be clipped into the tubular extension 30 due to the inclined surfaces 36 and 38 formed on the annular claws 32 and 34.
  • the second cover part 24 is thus held in a freely rotatable manner on the first cover part 16.
  • sealing rings 40 which lie in axially spaced grooves 42 on the outer circumferential surface of the housing 26, bear against the inner circumferential surface 44 of the filling opening 12.
  • the free rotatability between the two cover parts 16 and 24 allows the first cover part 16 to be screwed in without the second cover part 24 rotating, which would lead to increased wear of the sealing rings 40.
  • a sleeve 46 is held axially displaceably in the housing 26. This comprises a larger-diameter section 48 facing the first cover part 16 and a smaller-diameter section 50 facing the interior of the expansion tank 10.
  • the space between the sleeve 46 and the housing 26 is sealed by an annular sealing membrane 52, which with its inner bead-shaped edge 54 into a Groove 56 of the sleeve 46 engages and is clamped with its outer bead-shaped edge 58 between a shoulder 60 on the housing 26 and a support ring 62 engaging in it.
  • the support ring 62 also carries a radially inwardly extending annular bellows 64 which, together with the support ring 62, forms a closed annular space which is only accessible via a bore 66 passing through the support ring 62.
  • the support ring 62 and the bellows 64 are held by a closure part 68, which is inserted into the free end of the housing 26 facing the interior of the pressure compensating container 10 and is secured by a ring claw 70 on the closure part 68 and an annular claw 72 on the housing 26 comprising clip connection . With its annular surface 74 facing away from the closure part 68, the bellows 64 lies against an axially normal annular surface 76 of the sleeve.
  • the sleeve 46 has a radially outward-pointing flange 78 at the free end of the smaller-diameter section 50 on, which engages in an annular groove 80 of the closure member 68, the axial extent of which is greater than the axial extent of the flange 78.
  • the sleeve 46 can move axially when the bellows 64 is expanded between the position shown in FIG. 1 and the position shown in FIG.
  • the edge of the sleeve section 48 facing the first cover part 16 is designed as a valve seat 82 for an annular seal 84 which is clamped between a first steel membrane 86 and a second steel membrane 88.
  • the first steel membrane 86 is prestressed by a helical compression spring 90 against the valve seat 82, the helical compression spring 90 being supported on the one hand in a cup-shaped depression 92 in the cover 94 of the housing 26 and on the other hand in a pot-shaped depression of the first membrane 86.
  • the second membrane 88 is tensioned by a helical compression spring 98 against the surface of the ring seal 84 facing the sleeve 46, this helical compression spring 98 being supported on the one hand on the membrane 88 and on the other hand on an inner shoulder 100 of the sleeve 46.
  • the ring seal 84 lifts off the valve seat 82, so that pressure compensation can take place through the sleeve 46 and openings 102 in the housing cover surface 94 into the cover space 104, which has one or more gaps 106 in the annular extension 28 and a vent 108 in the expansion tank 10 communicates with the outside air.
  • the membrane 88 lifts off the ring seal 84 so that a pressure equalization between these two parts and a central opening 109 in the membrane 86 can take place.
  • the wall section of the filling opening 12 lying between the sealing rings 40 has a larger diameter than the outer circumference of the cover housing 26, so that an annular space 110 is thereby formed which is connected to a connecting piece 114 via a radial connecting channel 112. At the same time, this annular space 110 is connected to the interior 116 of the bellows 64 via a bore 115 in the cover housing 26 and the bore 66 aligned with the bore 114.
  • the connecting piece 114 is connected to the suction side of the coolant pump circulating the cooling medium in the motor vehicle cooling system.
  • the bellows 64 By connecting the interior 116 of the bellows 64 to the suction side of the coolant pump, the bellows contracts due to the reduced pressure, as a result of which the sleeve 46 is moved downward into the position of FIG. 1 by the force of the spring 90. As a result, the spring 90 is relaxed and thus the overpressure threshold value is reduced, so that the pressure difference by which the pressure in the coolant container must rise until the valve opens is the same when the coolant pump is at a standstill and when it is working.
