Definitions
- the invention relates to a cylinder head with a cooled valve seat ring after the preamble of claim 1.
- valve seat rings are known from DE 3829339, DD 287078 or DE 4328904. It is in the former Publications one to the cylinder head closed cooling channel provided in the valve seat ring. According to Fig. 5 DE 3829339 consists of the cooling channel of two with each other welded solid components into which the valve seat part is pressed. The cooled valve seat ring is cast in the cylinder head. The production of the cooled Valve seat ring made of solid components is expensive and leads to a relatively high weight penalty and as a result the pressing of the valve seat part in the cooling channel part to internal tensions.
- the invention therefore deals with the problem in generic valve seat rings to create a cooling channel which is easy to manufacture and lightweight.
- the sheet metal cooling channel of thin sheet steel can be compared with the production of solid material significantly weight be saved.
- the sheet cooling channel by bending, possibly also deep drawing a flat sheet produced.
- Another advantage of the sheet metal cooling channel compared consists of the known cooled valve seat rings in that regardless of the cross section of the valve seat part a freely selectable channel cross-section can be set can.
- the thickness of the thin steel sheet is preferably smaller 1.2 mm and is advantageously between 0.3 and 0.7 mm.
- a cooled valve seat ring 2 consisting of a valve seat part 3 and one welded to the valve seat part Sheet metal cooling channel 4, is by a composite casting with a cylinder head 1 connected.
- the valve seat part 3 has a chamfered by a Cone angle beta is marked.
- the sheet metal cooling channel 4 covers the valve seat part 3 in the region of this chamfer.
- valve seat part 3 has centering lugs 9 on, when welding the sheet metal cooling channel 4 on the valve seat part 3 fix.
- Figure 3 shows a section of a valve seat ring with welded cooling channel in cross section, with a sheet metal channel, the tubular member with a seat ring facing open side is executed, wherein the sheet metal channel with his two free legs to the valve seat ring gas-tight is attached.
- Fig. 4 shows a similar valve seat ring with an angle alpha ⁇ 45 corresponding to a cone angle beta of ⁇ 90 °.
- valve seat ring circumferential chamfer Cone angle or cone angle beta is usually between 70 ° and 110 °.
- the choice of the cone angle depends on the geometric Boundary conditions, in particular of the minimum wall thicknesses to be complied with.
- the sheet metal cooling channel is closed tubular designed with an annular cross-section and the seat ring has a recess adapted to the cooling channel diameter on, in which the sheet metal cooling channel is inserted.
- At least one weld can be omitted.
- the welding process takes place under partial vacuum instead of the welding process when closing the seam is not aggravated by leaking air.
