Description
Société dite Concordia Bergbau Aktiengesellschaft
Dans des moteurs à explosions,qui sont alimentés en combustibles gazeux, il faut, comme il est connu , 5faire varier également
les sections transversales de passage du gaz et de l'air en vue du réglage,pour que la composition du mélange reste invariable. Alors
que dans des moteurs fixes,dans lesquels les conditions de marche
ne varient que peu,la position rel ative des orifices d'admission
du gaz et de l'air est sans importance,il se présente dans des
moteurs dans lesquels le nombre de tours et la charge varient
<EMI ID=1.1>
par exemple dans des moteurs d'automobiles,l'inconvénient que la
composition du mélange ne reste pas la même. Comme la section trans
versale de la valve d'admission d'air est un multiple de celle de
la valve d'admission de gaz,la dépression dans la valve d'admission du mélange dépend ,non seulement du nombre de tours du moteur mais surtout de la position de l'organe d'étrangement pour 1? air dans chaque cas. Si l'on dispose l'orifice d'admission de gaz entre le moteur et la valve d'admission d'air,lorsque la valve d'admission d'air est fortement étranglée,dans la marche vide ,une forte pression agit sur la conduite d'amenée de gaz ce qui a pour résultat un enrichissement excessif du mélange. Le contraire se produit lorsqu'on dispose l'orifice d'admission de gaz en avant ,au lieu de le placer en arrière, par rapport à la valve d'étranglementde l'air.
On peut,il est vrai,compenser ces influences par la disposition de valves chargées par des ressorts ou d'organes de réglage additionnels analogues;toutefois leur dureté de fonctionnement n'est pas satisfaisante en raison des conditions imposées par la marche des moteurs d'automobiles.
La présente invention obvie aux inconvénients mentionnés, de la manière la plus simple, par le fait que les organes régulateurs de l'admission d'air et de gaz sont réuni s de telle sorte que l'écoulement du gaz s'effectue dans la section transversale d'étranglement de l'air. Un organe régulateur spécial pour le mélange devient. ainsi superflu.
pne forme de réalisation d'une valve d'étranglement suivant l'invention est représentée dans le dessin ci-joint sur lequel là fig. 1 est une vue en ,coupe longitudinale,la fig. 2 une vue
<EMI ID=2.1>
<EMI ID=3.1>
Dans une enveloppe tubulaire Aune valve d'étranglement B, en forme de papillon, est montée de façon à pouvoir tourner sur un axe creux C. Elle est actionnée par un levier D par l'intermédiaire d'une douille E. La conduite d'amenée de gaz débouche dans l'alésage de l'axe creux C. Dans la paroi de celui-si sont ménagées.des lumières qui,dans la position d'ouverture de la valve d'étranglement B,coincident avec des canaux correspondants F,méaagés dans l'épaisseur de cette valve Brandis/que lorsque la valve est fermée,ces lumières sont égal : ment fermées. Les lumières sont profilées de telle manière que pour chaque position de la valve d'étranglement.les sections transversales de passage du gaz et de l'air correspondent l'une 2 l'autre.
pour permettre en outre un réglage qualitatif du mélange,
on peut déplacer axialement 2'axe creux C au moyen du levier G. Les sections transversales de passage du gaz deviennent ainsi plus grandes ou plus petites tandis que les sections transversales de passage de l'air restent les mêmes. Un déplacement radial de l'axe creux C au lieu d'un déplacement axial,permet d'atteindre le
même résultat.
Company known as Concordia Bergbau Aktiengesellschaft
In explosive engines, which are supplied with gaseous fuels, it is, as is known, necessary to vary also
the cross sections for the passage of gas and air for the purpose of adjustment, so that the composition of the mixture remains invariable. So
than in stationary engines, in which the operating conditions
vary little, the relative position of the intake ports
gas and air is unimportant, it occurs in
engines in which the number of revolutions and load vary
<EMI ID = 1.1>
for example in automobile engines, the disadvantage that the
composition of the mixture does not remain the same. Like the trans section
versal of the air intake valve is a multiple of that of
the gas inlet valve, the vacuum in the mixture inlet valve depends not only on the number of engine revolutions but above all on the position of the throttle member for 1? air in each case. If the gas inlet port is placed between the engine and the air inlet valve, when the air inlet valve is severely constricted, in idle mode, strong pressure acts on the gas supply line which results in an excessive enrichment of the mixture. The opposite happens when the gas inlet is positioned forward, instead of rearward, of the air throttle valve.
One can, it is true, compensate for these influences by the arrangement of valves loaded by springs or similar additional regulating members; however their operating hardness is not satisfactory because of the conditions imposed by the operation of the engines of automobiles.
The present invention obviates the mentioned drawbacks, in the simplest way, by the fact that the regulating members of the air and gas admission are joined together so that the gas flow takes place in the section. transverse air throttle. A special regulating organ for the mixture becomes. thus superfluous.
pne embodiment of a throttle valve according to the invention is shown in the accompanying drawing in which fig. 1 is a view in longitudinal section, FIG. 2 a view
<EMI ID = 2.1>
<EMI ID = 3.1>
In a tubular casing Aa throttle valve B, in the shape of a butterfly, is mounted so as to be able to turn on a hollow shaft C. It is actuated by a lever D via a socket E. gas supply opens into the bore of the hollow shaft C. In the wall of the latter, there are openings which, in the open position of the throttle valve B, coincide with the corresponding channels F, mixed in the thickness of this Brandis / valve that when the valve is closed, these lights are also closed. The lumens are profiled in such a way that for each position of the throttle valve the cross sections of gas and air passage correspond to each other.
to also allow a qualitative adjustment of the mixture,
the hollow shaft C can be axially displaced by means of the lever G. The cross sections of the gas passage thus become larger or smaller while the cross sections of the air passage remain the same. A radial displacement of the hollow axis C instead of an axial displacement, makes it possible to reach the
same result.
