Definitions

  • the invention relates to a lightweight valve, in particular for an internal combustion engine according to the preamble of Claim 1.
  • valve is known from US-A-1 506 900 or DE 36 25 590 A.
  • the valve disclosed in DE-A-3 625 590 is said to contribute to development an engine type with heat-insulated combustion chambers represent.
  • the one facing the combustion chamber Valve plate is particularly thin-walled. This measure should a low heat absorption of the valve plate and cause correspondingly low heat losses.
  • About the thin walls of the valve plate are to be extended of the valve stem additional components as a support provided between the valve plate and valve stem.
  • Lightweight valves are also known for. B. from the DE 1 960 331 A, EP 0 091 097 A, US 2,731,708 or U.S. 1,294,416.
  • valve Cavity to create a relatively large, unsupported Floor area formed towards the combustion chamber, which in operation - especially with minimized wall thicknesses - due to the combustion pressure is deformed.
  • the through these deformations resulting displacements on the peripheral surface of the Valve seat contribute to premature wear of the Seat and additional stress on the valve.
  • these deformations cause additional stress in the area of the joint between the valve plate and valve cone with the risk of the connection bursting open.
  • a support of the valve plate is in itself from the US 2,439,240 known.
  • the solution presented there is due to the design of the support in terms of manufacturing technology consuming.
  • valve disc is also supported against the stem known from DE 36 25 590 A.
  • a disadvantage of those disclosed there Solutions is, however, that the support with the help an additional adapter between the valve disc and shaft is fixed, and that the wall thickness of the valve plate is very low, so that deformation of the Valve head are to be expected.
  • the invention is therefore concerned with the problem of a lightweight valve the rigidity in a simple way to increase the valve head and manufacture the To facilitate the valve.
  • Deformation values can be achieved with valves according to the invention realize that in the range of values of valves with a Valve head made of solid material.
  • the mass reduction this lightweight valve is at least 40% in comparison with solid steel valves.
  • the embodiment according to claim 1 represents an extensive Change from the usual design for lightweight valves because the valve cone is no longer integral with the Valve stem, but is manufactured as a single part and the valve stem itself - possibly with an enlarged diameter - continues to the valve plate.
  • the shaft is preferably drawn or welded Pipe made or made of solid material.
  • the valve cone is preferably fixed to the stem by soldering or welding.
  • 'Radially inside' means: away from the outside diameter of the valve plate.
  • the valve according to the invention becomes a lightweight valve created that even with thin walls and accordingly low weight and high rigidity.
  • the invention is based on the basic idea that on the Valve plate acting gas forces through direct support of the valve plate against the stem.
  • the valve disc is supported against the valve stem in connection with the valve cone a rigid Rotational surface structure with an approximately triangular cross-section.
  • a lightweight valve is known from US 4,834,036 which the shaft extends into the area of the valve plate, however, the valve head is a light, cast or forged solid material Titanium base like titanium aluminide, so this valve is generic does not belong to the hollow valves according to the invention.
  • a valve from US 1,506,900 is also still out known in 1924, which has a similar structure, from which the invention differs, however, by a different one Wall thickness ratio and another training regarding the connection of the shaft end to the valve disk different.
  • the relatively thin one disclosed there Wall thickness of the valve disc compared to the valve cone is unfavorable in terms of strength, as is the breakthrough in Valve plate for receiving the valve stem end.
  • a valve 1 for an internal combustion engine consists of a Shaft 2, a valve base, not shown, a funnel-shaped Valve plug 3 and one piece with the valve plug manufactured valve disc 4.
  • the diameter of the Shaft is expanded at the level of valve cone 3.
  • On his the lower end is the stem 2 with the valve plate 4 welded.
  • the valve cone 3 is at its upper end welded to the shaft 2.
  • the valve cone 3, the valve disk 4 and the lower, connecting both, expanded Shaft ends together form a rigid rotational surface structure.
  • the wall thickness of the valve cone 3 is smaller than the wall thickness of the valve plate 4.
  • valve plates 4 and valve cone 3 not in one piece, but by one Weld seam joined together.
  • the shaft is there made of solid material.
  • the shaft can be below the Weld also have a smaller diameter than in the area above the weld.
  • valve plate 4 and valve cone 3 are in one piece and in the valve plate 4 is a centering for the end of Shaft 2 provided.
  • a welded joint is only between the upper end of the valve plug 3 and the stem intended.
  • the wall thickness of the valve plate 4 greater than the wall thickness of the valve plug 3.
  • Fig. 4 is a valve plate 4 with a molded collar-shaped support according to claim 5 shown.
