Autor vynálezu SACHOV GEORGI BOGOMILOV dipl. ing. a MARVAKOV IVAN VELIKOV,PETRITSCH (BLR) {54) Membránový tlumič vodních rázů 1Author of the invention SACHOV GEORGI BOGOMILOV dipl. ing. and MARVAKOV IVAN VELIKOV, PETRITSCH (BLR) {54) Diaphragm shock absorber 1
Vynález se týká membránového tlumičevodních rázů, sestávajícího z horní a dolníčásti, které jsou uspořádány v jeho horníkomoře a jsou naplněny kapalinou, přičemžjsou spojeny zpětným ventilem, jakož i zpružné membrány, na které je pomocí vře-tena upevněn ventil, a z dolní komory vy-tvořené v tělese, které je uspořádáno v dol-ní části tlumiče a je opatřeno vstupním ot-vorem pro spojení s tlakovým potrubím, vý-stupním otvorem a sedlem kuželového ven-tilu. je znám membránový tlumič, který sestá-vá z dolní a horní komory, které jsou oddě-leny pružnou membránou. Horní komora jerozdělena na dolní a horní část, přičemžobě tyto části jsou vzájemně spojeny zpět-ným ventilem a jsou naplněny tlakovou ka-palinou a stlačeným plynem. Na pružnémembráně je prostřednictvím vřetena upev-něn kuželový ventil, jehož sedlo je provede-no v tělese, které se nalézá v dolní částitlumiče a je opatřeno vstupním otvorem ktlakovému potrubí, jakož i výstupním otvo-rem.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a diaphragm shock absorber consisting of an upper and a lower portion arranged in its minerals and filled with a fluid, connected by a non-return valve and a flexible diaphragm to which a valve is fixed by a boom. in the body which is arranged in the lower part of the damper and is provided with an inlet opening for connection to the pressure line, outlet opening and seat of the cone valve. a diaphragm damper is known which consists of a lower and an upper chamber which are separated by a flexible membrane. The upper chamber is divided into lower and upper portions, whereby these portions are connected to each other by a non-return valve and are filled with pressurized fluid and compressed gas. A tapered valve is mounted on the flexible diaphragm by means of a spindle, the seat of which is provided in the housing which is located in the lower silencer and is provided with an inlet opening for the pressure line as well as an outlet opening.
Nevýhodou tohoto membránového tlumi-če je provozní nespolehlivost zapříčiněnápřítomností kapaliny a plynu v horní komo-ře, které jsou pod tlakem. Kromě toho mu-sí být objem horní části komory velký. 2A disadvantage of this membrane damper is the operational unreliability caused by the presence of liquid and gas in the upper chamber under pressure. In addition, the volume of the upper chamber must be large. 2
Vynález má za úkol vyloučit zmíněné ne-výhody a vytvořit membránový tlumič vod-ních rázů, který by v provozu působil auto-maticky se zvýšenou bezpečností a citlivos-tí.It is an object of the present invention to avoid the aforementioned disadvantages and to provide a water shock membrane damper which would operate automatically with increased safety and sensitivity.
Nevýhody odstraňuje membránový tlumičvodních rázů, sestávající z horní a dolníčásti, které jsou uspořádány v jeho horníkomoře a jsou naplněny kapalinou, přičemžjsou spojeny zpětným ventilem, jakož i zpružné membrány, na které je pomocí vře-tena upevněn ventil, a z dolní komory vy-tvořené v tělese, které je uspořádáno v dol-ní části tlumiče a je opatřeno vstupním ot-vorem pro spojení s tlakovým potrubím, vý-stupním otvorem a sedlem kuželového ven-tilu podle vynálezu jehož podstatou je, žehorní část horní komory je spojena otvorems vnější atmosférou, přičemž na pružnémembráně je uspořádána pružina, a to s vý-hodou v dolní části horní komory, působícíve smyslu otevírání kuželového ventilu. U jiné varianty konstrukce membránové-ho tlumiče vodních rázů je pružina uspořá-dána v dolní komoře mezi kuželovým ven-tilem a přírubou pevně uchycenou v tělesepod pružnou membránou.Disadvantages are eliminated by the diaphragm shock absorber consisting of the upper and lower portions, which are arranged in its minerals and are filled with liquid, connected by a non-return valve, as well as the flexible diaphragm on which the valve is fixed by the valve, and from the lower chamber formed in a body which is arranged in the lower part of the damper and is provided with an inlet opening for connection to the pressure line, outlet opening and seat of the conical valve according to the invention, the essence of which is that the upper part of the upper chamber is connected openly to the outer atmosphere, wherein a spring is provided on the flexible diaphragm, preferably in the lower part of the upper chamber, in the sense of opening the conical valve. In another variant of the construction of the diaphragm buffer, the spring is arranged in the lower chamber between the conical valve and the flange firmly attached to the body by the flexible membrane.
Podle další konstrukční varianty membrá- nového tlumiče jsou uspořádány současně dvě pružiny v dolní komoře a v dolní části horní komory, 204180According to another design variant of the diaphragm damper, two springs are arranged simultaneously in the lower chamber and in the lower part of the upper chamber, 204180
