Definitions
- the invention relates to a hollow valve for internal combustion engines for lowering the temperature and Weight reduction.
- Hollow valves are a special type, especially those with higher loads Exhaust valves, represent. On the one hand, they are mainly used to lower the temperatures in the fillet and plate area also serves to reduce weight. You sit down Hollow valves to lower the temperature, the cavity becomes about 60% of the volume filled with metallic sodium, which is used to transport heat from the valve head into the Valve stem provides. From there, the heat is dissipated via the valve guide.
- the base body is also drilled from the shaft end. However, the bore is closed by induction heating of the shaft end with subsequent forging, the full shaft end piece being attached by friction welding. A friction weld of the full shaft end piece with the drawn "end of the base body offers greater security. This embodiment is used predominantly in high-performance engines.
- valve stem seals to high temperatures Valve, however, only up to the vicinity of the sealing lip of the outer diameter predominantly elastomeric valve stem seals. A longer hole can only if no valve stem seal is used.
- Hollow valves can be designed as monometal valves, but they are more common Bimetallic valves, in which the stem piece made of a ferritic-martensitic steel and the Headpiece made of austenitic material or a nickel-based material. This Material is thermoformed during the manufacture of the head piece before it is drilled hollow.
- the production of very light valves is already known, for which stem and Headboard as a one-piece, hollow, cylindrical component made of a ductile sheet metal is, as EP 0 619 419 B1 shows, but it is a monometal valve for lower loads, because the use of austenitic material closed previously cold forming processes.
- the cavity is sufficient in the known valve deep-drawn valve body to the extreme end of the stem. A dissipation of heat through a possibly used valve filling in the shaft end piece would be under certain circumstances harmful.
- the use of such valves for temperature reduction is at least Valve guides with final valve stem seals are very questionable.
- the invention has for its object to a hollow bimetal valve of very low mass create, which at the same time the demands for great mechanical wear resistance and resistance to high temperature corrosion met and compared to the previously known manufacturing process is particularly economical to manufacture.
- the invention solves this problem with the features of the characterizing part of claim 1.
- a valve designed according to the invention permits the use of the deep-drawing process for the part of the valve body which extends from the stem end part into the plate area and consists of an austenitic material.
- the largest possible internal bead on the weld seam is created by the welding process (Welding expulsion), which creates the connection between the drilled cavity in the Shaft end part and the cavity in the valve body either completely or partially closes.
- the coolant present in the valve body is thus penetrated into the Cavity of the stem end part prevented and the valve stem seal at the end of the Valve guide protected against damage due to excessive temperature.
- the cavity in the Shaft end piece therefore only serves the desired weight reduction.
- the cover that closes off the plate area is preferably covered with the seat armor Valve body connected. This simplifies the manufacturing process and a economical production ensured, although the valve consists of three parts. Training of the valve body as a deep-drawn component enables the economically Vary wall thickness and thus adapt to the load requirements.
- the valve consists essentially of the three parts shaft end part 1, valve body 2 and Cover 3.
- the shaft end part 1 is provided with a bore 4 in order to close the cavity 5 create.
- the valve body 2 with the plate, the fillet area 7 and in the Valve guide-reaching stem part 9 is a deep-drawn component.
- the shaft end part is 1 in contrast, made in the usual way from a ferritic-martensitic material.
- the both parts 1 and 2 are preferably connected to one another by friction welding, the inner bead (welding expulsion) 10 extending far inward forms.
- the Cavity divided into sections 5 and 11, with a small passage cross section 12th can be preserved.
- the valve head In the plate area, the valve head is closed by a cover 3, the Seat armor 15 also serves as a welded joint.
- Figures 2 to 5 are different designs of the contact surfaces between the Valve head shown in the plate area and the cover 3.
- the armor 15 serves as a connecting element between the cover 3 and the valve body.
