Description

Popychacz zaworu do silnika spalinowego 2 Przedmiotem wynalazku jest ,papychacz zaworu do silnika spalinowego.Znane sa popychacze do silników spalinowych skladajace sie z cylindrycznej tulei wykonanej z blachy i zakonczonej z jednej strony poprzeczna czolowa scianka, której obrzeza otacza wspólsrod- kowo usytuowane w niej wglebienie. Wada zna¬ nych popychaczy jest ich mala sztywnosc, obniza¬ jaca ich wytrzymalosc i przez to koniecznosc sto¬ sowania popychaczy o ciezszej konstrukcji.Celem wynalazku jest usuniecie tych wad. Cel ten, zgodnie z wynalazkiem zostal osiagniety przez zastosowanie obrzeza tulei wykonanego w postaci kolnierza zaopatrzonego na poziomie poprzecznej, czolowej scianki w wystajace do wewnatrz wy¬ tloczenia. Ponadto — poprzeczna czolowa scianka uksztaltowana zostala w ten sposób, iz zawiera ona plaska pierscieniowa powierzchnie otaczajaca srodkowe wglebienie scianki oraz otaczajacy te powierzchnie pierscieniowy rowek, przechodzacy w zewnetrzne obrzeze scianki.Przedmiot wynalazku uwidoczniony jest w przy¬ kladzie wykonania na rysunku, na którym fig. 1 przedstawia widok górny popychacza i fig. 2 przekrój poprzeczny popychacza wzdluz linii A—A uwidocznionej na fig. 1.Popychacz uwidoczniony na fig. 1 sklada sie z cylindrycznej tulei 1 zawierajacej na jednym koncu poprzeczna, czolowa scianke 2 z obrzezem 3 i wspólsrodkowym wglebieniem 4. Poprzeczna czolowa scianka 2 zawiera wokól wglebieni? 4 plaska powierzchnie 6 oraz otaczajacy ja rowek 7 przechodzacy w zewnetrzne obrzeze 3. Zewnetrzne obrzeze 3, od strony wewnetrznej polaczone jest 5 z rowkiem 7.Cylindryczna tuleja 1 na poziomie czolowej scianki 2 zaopatrzona jest w wytloczony do wewnatrz wystep 8. Przestrzen pomiedzy czolowa scianka 2 i krawedzia obrzeza 3 jest przeznaczona io do wtloczenia korka z twardego metalu, z którym wspólpracuje krzywka sterujaca praca zaworu.Rowek 7 zapewnia wygodne usuwanie wtloczonego korka. - Wystajace do wewnatrz wytloczenie 8 tworzy wzmacniajaca podpore czolowej scianki 2. 15 Uksztaltowanie czolowej scianki 2 w plaszczyz¬ nie poprzecznego przekroju oraz zastosowanie pod¬ pory w formie wystajacego do wewnatrz wytlo¬ czenia 8 tworzy popychacz o duzej sztywnosci.Sztywnosc popychacza jest równiez zwiekszona, 20 a jego ciezar zmniejszony dzieki wytlaczaniu go z cienkosciennej blachy. / PL PLValve tappet for internal combustion engine 2 The subject of the invention is a valve pusher for an internal combustion engine. There are known tappets for internal combustion engines, consisting of a cylindrical sleeve made of sheet metal and ending on one side with a transverse front wall, the periphery of which is surrounded by a concentric recess in it. The disadvantage of the known pushers is their low stiffness, which reduces their strength and therefore the necessity to use thicker pushers. The object of the invention is to remedy these disadvantages. This object is achieved according to the invention by the use of a flange-shaped rim of the sleeve provided at the level of the transverse front wall with embossing protruding inwardly. Moreover, the transverse front wall has been shaped in such a way that it has a flat, ring-shaped surface surrounding the central depression of the wall and a ring-shaped groove surrounding these surfaces, passing into the outer periphery of the wall. The subject of the invention is shown in the example of the embodiment in the drawing in which Fig. 1 shows an upper view of the pusher and fig. 2 a cross-section of the pusher along the line A-A shown in fig. 1. The pusher shown in fig. 1 consists of a cylindrical sleeve 1 with at one end a transverse end wall 2 with a rim 3 and a concentric indentation 4. The transverse front wall 2 includes around the depression? 4 flat surface 6 and the surrounding groove 7 passing into the outer rim 3. The outer rim 3 is connected on the inside with the 5 to the groove 7. The cylindrical sleeve 1 at the level of the front wall 2 is provided with a protruding inwards 8. The space between the end wall 2 and the edge of the rim 3 is intended for the insertion of a hard metal plug, with which a cam controlling the operation of the valve cooperates. The groove 7 ensures convenient removal of the pressed-in plug. - The inwardly protruding embossment 8 forms a reinforcing support of the end wall 2. 15 The shaping of the end wall 2 in the plane of the transverse section and the use of the support in the form of an inwardly protruding emboss 8 creates a pusher of high rigidity. The stiffness of the follower is also increased. 20 and its weight is reduced thanks to its stamping from thin-walled sheet metal. / PL PL
