Definitions

  • valve known from DE 36 25 590 A is intended to contribute for the development of a motor type with heat-insulated Represent combustion rooms. This is the combustion chamber facing valve plate is particularly thin-walled. This measure aims at low heat absorption of the valve disk and cause correspondingly low heat losses. Around to allow the thin walls of the valve plate are in Extension of the valve stem additional components as a support provided between the valve plate and valve stem.
  • Lightweight valves are also known e.g. from the DE 19 60 331 A, EP 0 091 097 A, US 2,731,708 or U.S. 1,294,416.
  • the Aim to have the largest possible inside the 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 for additional stress on the valve. Also effect these deformations an additional load 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, however, is that with the support an additional adapter between the valve disc and shaft is fixed, and that the wall thickness of the Valve plate is very small, causing 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 of this Lightweight valves is at least 40% compared to Solid material steel valves.
  • the embodiment according to claims 1 to 3 represents a Extensive departure from the previously common design for Lightweight valves because the valve cone is no longer in one piece is made with the valve stem, but as a single part and the valve stem - if necessary with enlarged diameter - continues towards the valve disk.
  • 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 of the valve disk acting gas forces by direct support of the Take valve plates against the shaft.
  • a flexurally rigid rotating 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 based on titanium 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 other training related the connection of the shaft end to the valve plate different.
  • the relatively thin wall thickness disclosed there of the valve disc compared to the valve cone is firm unfavorable, as well as the breakthrough in the 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 of the shaft 2 is welded to the valve plate 4.
  • the valve cone 3 is at its upper end the shaft 2 welded.
  • the valve cone 3, the valve disk 4 and the lower, extended shaft end connecting the two together form a flexurally rigid rotating surface structure.
  • the wall thickness of the valve cone 3 is smaller than that 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 consists 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 uund 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 cone 3 and the shaft.
  • the wall thickness of the valve disk 4 is also here greater than the wall thickness of the valve plug 3.
  • Fig. 4 is a valve plate 4 with a molded collar-shaped Support shown.
