Definitions
- the invention relates to a closure lid for a container under internal pressure, with a fixable by turning in a nozzle of the container lid body, and with a handle provided with a lid, which is operatively connected to the lid body. It also relates and especially to a closure cap for the fuel tank of a motor vehicle which is under slight overpressure.
- the tank In order to prevent the escape of fuel vapors, the tank must not be opened as long as it is provided for the slight overpressure intended for normal operation, ie the pressure is above a first threshold value. In normal operation, attention must be paid to good sealing. This also applies to the pressure relief valve which opens at a second, higher, threshold value, which is to be correspondingly arranged and designed.
- the coupling device arranged between the cover body and the cover releases the rotary connection between the cover body and the cover during overpressure prevailing in normal operation in the fuel tank, so that the fuel tank can not be opened. Only when the pressure has dropped below the first threshold, the opening is possible.
- the driving ring forms the axially movable part of the clutch, which is actuated by a responsive to the pressure difference between the container interior and the atmosphere actuator.
- the driving ring communicates with the lid body and the lid, with one of the two permanently and with the other only when the fuel tank is depressurized.
- the lid body As an actuator is preferably used with the lid body firmly connected membrane, which has the advantage over a piston to be tight. Due to its annular shape and supporting it annular disc can also interact with the pressure relief valve, which is a special simple and easy to assemble construction results. The membrane thus performs a dual function. In addition, the pressure relief valve can be made sensitive and reliable.
- FIG. 1 shows an embodiment of a device according to the invention in longitudinal section
- FIG. 2 Exploded view of Fig. 1
- Fig. 3 Detail C in Fig. 1, enlarged.
- Fig. 1 the closure cap according to the invention for a fuel tank, not shown, summarily denoted by 5. It is in operation under a not very high internal pressure (approximately between 40 and 200 mbar) and has an upwardly projecting filler neck 1, on which the lid body 5 fits. On its longitudinal axis 4 refer in the following the terms "top”, “bottom” and “height” etc.
- the nozzle 1 forms at its upper end a seat 2 for a seal 12 and ends in a downwardly beaded collar 3, the fixing the closure cap in the neck a thread or - as here - forms the female part of a bayonet.
- the closure lid 5 consists essentially of a lid body 6, a lid 14 and dome parts according to the invention in between.
- the lid body 6 has the shape of a plate 7 with an outer plate edge 7.1, to which a downwardly projecting hollow cylinder 8 with äuseren threaded parts or male bayonet parts followed, here in a sacking 10 with Lö- ehern 11 ends.
- the holes ensure that inside the hollow cylinder 8, the internal pressure of the container prevails.
- the lid 14 with a handle 15 for rotating the closure lid 5 is mounted above the plate 7 and has a number distributed over its circumference snap hook 16, by which he cleats with the plate 7, but with respect to this is rotatable.
- a lid body 6 tightly secured membrane 20 and a driving ring 22 is provided as a coupling device. If the internal pressure is greater than the atmospheric pressure, he presses the membrane 20 and this in turn the driving ring 22 in the air. Thus, the membrane 20 holds the driving ring 22 against the force of a pressure spring 23 arranged above it in the raised position, separated from a sliding ring 21.
- the compression spring 23 is designed for a first threshold value of the internal pressure over which the lid body 5 may not be opened.
- the selective rotary joint is shown with reference to FIG. 2.
- the lid body 6 from above and the lid 14 can be seen from below, between the driving ring 22.
- This (22) has at its top along a circle arranged first ribs 25 with breaks 25.1.
- the lid 14 has on its inside a corresponding number of second ribs 26, here they are nose-shaped, which engage regardless of the height position of the driving ring 22 (and thus independent of the internal pressure) in the interruptions 25.1.
- the driving ring 22 At its downwardly beaded edge 22.1 (ie at its underside), the driving ring 22 has a number of recesses 27, engage in the in the lowered position inwardly directed projections 28 on the outer edge of the plate 7 of the lid body 6.
- the recesses 27 are of such low height that the protrusions 28 disengage as soon as the internal pressure exceeds the first threshold (for example, 40 mbar) and thus raises the diaphragm 20 - then the rotary connection is interrupted.
- the membrane 20 has at its circular outer edge an all-round bead 20.1, which is held by a clamping ring 30 close to the plate-shaped part of the lid body 6.
- the clamping ring 30 is again clipped by means of a number snap hook 30.1 with the lid body 6.
- To the bead 20.1 connects inwardly a bellows-like torus 20.2, within which the active surface 20.3, the actual membrane, is stretched. It is a circular ring with a washer 31 resting on its underside, for forming an additional pressure relief valve, as described below.
- the pressure relief valve is largely housed in the space 43 in the interior of the cover housing. It is formed by a valve body 40. This is a top of a partition 40.4 large area closed downwardly extending cylinder 40.2, at its upper edge a flange 40.1 protrudes outwards, which engages over the active surface 20.3 of the annular membrane 20 from the inside / below partially. Below the cylinder ends 40.2 in an extension to which a spring plate 42 is supported. Between the spring plate 42 and the disc 31 at the bottom of the membrane 20 is seated a further compression spring 41, which presses the flange 40.1 of the valve body 40 to the membrane 20.
- the valve body 40 may follow the deformation of the diaphragm 20 without the pressure relief valve leaking or even opening.
- the releasable rotary connection can also be provided between the driving ring 22 and the cover 14 (ie vice versa), for which purpose the coupling elements 25 to 28 are to be reshaped accordingly.
- the coupling elements can be designed arbitrarily, as long as they produce only on one side of the driving ring 22 a permanent and on its other side a depending on the height position temporary rotational connection.
