Description

Najdluzszy czas trwania patentu do 14 lipca 1941 r.Wynalazek dotyczy dalszych zmian u- rzadzenia wedlug patentu Nr 5 381 i ma na celu zapobiezenie otwarciu wlaczonego w przewodzie pary do wtryskacza organu zamykajacego podczas doplywu malych i- losci pary wskutek nieszczelnosci zaworu parowego.UrzadiziemJie polega na tern, ze przewód parowy o malym przeswicie do dysz wtry¬ skacza ldb nazewnatrz pozostaje otwarty przy koncowem polozeniu organu zamyka¬ jacego.Na rysunku uwidoczniono kilka przy¬ kladów wykonania. Na fig. 1 w tloczku 16 jest wykonany kanal 20 o malym przeswi¬ cie, laczacy komory pod i nad tloczkiem.Równiez znajduje sie w kadlubie wtryska¬ cza kanal 21, laczacy komore 8 pod tlocz¬ kiem 16 z komora parowa 9 wtryskacza.Zamiast tloczka 16 moze byc zastosowany zawór lub kadlub zaworowy, laczacy ko¬ mory pod i nad zaworem.Na fig. 2 uwidoczniono przyklad wyko¬ nania, w którym kanal, laczacy komory 8 i 9, jest wykonany równiez w tloczku.Na fig. 3 pokazano tloczek 16 ze spla¬ szczeniami, przez co sa zwolnione male przekroje dla przelotu pary zarówno do dysz, jak i na górna strone tloczka.Do osiagniecia tego samego celu moze byc tloczek mniej szczelnie dopasowany do umozliwienia przelotu pary obok po-wierzchni walcowej tloczka. Gdy para ply¬ nie przy zaworze parowym wskutek jego nieszczelnosci do wtryskacza, to dostaje-sie przez kanaly 20 lub 21 i nieszczelnosci or¬ ganu zamykajacego do dysz wtryskacza lulb przez zawór wylotowy 15 nazewnatrz i w tym celu prowadzacy z komory paro¬ wej do komory wylotowej trzpien 17 or¬ ganu wylotowego jest niezupelnie uszczel¬ niony ze scianka miedzy komora parowa i wylotowa. PLThe longest term of the patent until July 14, 1941 The invention concerns further changes to the device according to the patent No. 5 381 and is aimed at preventing the opening of the closing element connected in the steam line to the injector during the inflow of small steam due to leakage of the steam valve. On the other hand, the steam line with a small opening to the nozzles or outside remains open at the end of the closing member. The drawing shows a few examples of implementation. In Fig. 1, the piston 16 is provided with a channel 20 with a small gap, connecting the chambers below and above the piston. There is also an injection channel 21 in the hull connecting the chamber 8 under the piston 16 with the vapor chamber 9 of the injector. of the piston 16, a valve or a valve body may be used, connecting the chambers above and below the valve. Fig. 2 shows an embodiment in which the channel connecting chambers 8 and 9 is also provided in the piston. Fig. 3 shows the plunger 16 has a ruffle, thereby relieving the small sections for the passage of the steam both to the nozzles and to the top of the plunger. To achieve the same purpose, a plunger may be less closely fitted to allow the steam to pass past the cylindrical surface of the plunger. When steam flows at the steam valve due to its leakage to the injector, it passes through the ducts 20 or 21 and the leakage of the closing organ to the nozzles of the injector or through the outlet valve 15 to the outside and, for this purpose, from the steam chamber to the outlet chamber. the stem 17 of the exhaust body is completely sealed to the wall between the steam and exhaust chambers.

Claims

Patent claims. 1. Injector non-suction according to pairs of tent No. 5381, characterized by the use of a conduit with a small gap (21), connecting the two parts separated (8, 9) after closing the closing element with the injection, thanks to which a small amount of steam, Flying due to leakage of the steam valve may flow into the nozzles of the injector, or through the outlet valve may flow outwards without lifting the closing member. 2. An injector according to claim 1 with a piston (16) connected to the steam pipe to the injector, characterized by the fact that in this piston there is a channel (20) connecting the chambers under and above the piston, as a result of which small amounts of steam flowing through the channel (20) in the piston (16), may extend through the opening of the exhaust valve without lifting the piston (16). 3. An injector according to claim 1 with a piston connected to the steam line to the injector, characterized in that the piston fits tightly to the cylindrical seat it contains, as a result of which small amounts of steam may enter the nozzles or into the chamber outside the piston.
