Abstract

The IC engine inlet manifold (1) incorporates a lengthwise slot which is closed by a sealing strip (2) made of elastic material. Connection to the individual inlet branches (8) of the cylinders (9) can be achieved by unions (5) which are joined to the manifold via a sleeve (6) on an elastic damping insert (3). The position of the elastic damping insert can be determined by a local thickened portion (7) at the opening in the manifold, and by the sealing strip.

Description

Vynález ia týká sacího potrubí pro spalovací motory, jehož účelem je snížit hluk vyzařo- váný do okolního prostoru, ennžžt mechanické namáhání vlastními vibracemi a snížit napětí od případných rozdílných tepelných dilataci. ,The invention also relates to an intake manifold for internal combustion engines, the purpose of which is to reduce the noise emitted into the surrounding space, to reduce the mechanical stresses caused by its own vibrations and to reduce the stresses from possible different thermal dilatations. ,

Dosud známá sací' potrubí jsou provedena jako jeden pevný celek, který tvoří vlastní trubka s hrdlý* pro přívod vzduchu k jednotliýým pracovním válcům.The prior art intake manifolds are designed as a single unit which forms a separate tube with a throat for supplying air to the individual work rolls.

Daaěí známá provedení spočívají v tom» že vlastní sací trubka je příčně dělená na několik čáásí, které jsou pevně spojeny s hrdly pro přívod vzduchu ' k pracovním válcům.' Jedno tlivé trubky jsou pak ' mezi sebou pružně spojeny.Other known embodiments are that the suction tube itself is transversely divided into a plurality of parts which are rigidly connected to the air inlets to the work rolls. The individual pipes are then resiliently connected to each other.

Nevýhodou dosud známých provedení je přenáženi provozního kmitání od válcových jednotek přes hrdla ' na sací trubku. Takto rozkmitávaná sací trubka vyzařuje hluk, trpí mechanickým namáháním od'vibrací a případně i od deformaci které vznnkají v důsledku rozdílné tepelné roztaživosti válcových jednotek oproti potrubí.A disadvantage of the hitherto known embodiments is the transmission of the operating oscillation from the cylindrical units via the orifices to the suction pipe. The suction pipe vibrated in this way emits noise, suffers from mechanical stresses due to vibrations and possibly from deformation which arise due to the different thermal expansion of the cylindrical units compared to the piping.

Tyto nevýhody odstraňuje provedení sacího'potrubí pro spalovací motory podle vynálezu, jehož podstatě spočívá v tom, že'sací ' trubka je'opatřena podélnou mezerou,' uzavřenou pružnou ližtou a nátrubky jsou na sací trubce uloženy pružně přes tlumicí vložku, přičemž čelní otvor sací trubky je uzavřen zátkou z mateřálu tlumicího vibrace. Tlumicí vložka je pro z^jižt^ění polohy opatřena zesílením, provedeným, kolem otvoru sací trubky, kterým je zároveň s těsnicí ližtou středěna. .These disadvantages are overcome by the design of the intake manifold for internal combustion engines according to the invention, which consists in that the intake pipe is provided with a longitudinal gap, closed by a flexible rail and the sleeves are resiliently mounted on the intake pipe via a damping insert, The tube is closed by a plug of the vibration damping mattress. The damping insert is provided with a reinforcement around the opening of the suction tube to center the position of the sealing strip in order to determine the position. .

Příklad provedení sacího potrubí podle vynálezu je znázorněn na přiocenném výkrese, kde obit. ' 1 znázorňuje celkové uspořádáni sacího po o rubí, obr. 2 znázorňuje detail sací trubky s mezerou a otvory, obr. 3 znázorňuje řez sací trubkou v mstě otvoru a obr. 4 znázorňuje příčný řez přes sací trubku v mstě, jejího spojjení s nátrubkem, navazujícím na sací kanál válcových Jednotek. .An exemplary embodiment of an intake manifold according to the invention is shown in the appended drawing where the obit. Fig. 2 shows a detail of the suction pipe with a gap and openings; Fig. 3 shows a cross section of the suction pipe in the city of the opening; and Fig. 4 shows a cross section through the suction pipe in the city and its connection with the sleeve. connected to the suction channel of the cylindrical units. .

Sací trubka J. je opa třena podélnou ms^erou ' , uzavřenou pružnou ližtou ' , která tlumí .The suction tube 1 is supported by a longitudinal gauge ', closed by a flexible rail', which dampens.

vlastní ' vibrace sací trubky Jednoolivé nátrubky ' , nevsauuící na ' sací kanály 8. válcových jednotek £, jsou těsní nasazeny na vnější · povrch sací trubky £ přes pružnou tlumicí vložku £. Poloha tlumicí vložky 5_ vůči sací trubce £ je zajištěna zesílením 6 jejího profilu, provedeným kolem otvorů 7_ sací trubky £, kterým je společně s těsnicí lištou £ středěna.The actual 'vibration of the suction pipe' The single-lined nozzles, which do not fit onto the 'suction channels of the cylindrical units 8, are sealed onto the outer surface of the suction pipe through a flexible damping insert. The position of the damping insert 5 relative to the suction tube 4 is ensured by a reinforcement 6 of its profile, made around the openings 7 of the suction tube 4, by which it is centered together with the sealing strip 4.

K zaslepení čelního otvoru Д£ sací trubky £ je použito .zátky 10 z maaeeiálu tlumicího vibrace, kuppíkladu pryže. .Plugs 10 of vibration damping material, such as rubber, are used to plug the front opening of the suction tube. .
