Definitions

the invention relates to a reciprocating piston internal combustion engine with a valve seat which can be inserted into the gas exchange duct as a receiving bore in the cylinder head base in the manner of a bushing and which has at least one annular space for the coolant flow which is delimited on the outside by the receiving bore in the cylinder head and which faces the cylinder Side in a right-angled part of the receiving bore is supported radially over its cylindrical lateral surface and axially on the shoulder formed, the forces exerted on the valve seat surface by the valve plate running apart within the valve seat as radial and axial force components.
DE-AS 23 55 292 discloses a cooled poppet valve for a reciprocating piston internal combustion engine, the valve seat of which extends into the gas exchange duct.
the valve seat is supported radially and axially in a part of the receiving bore which is offset on the cylinder side and has an annular cooling channel which is connected to the cooling water circuit of the internal combustion engine.
a valve seat of this design is subject to considerable bending stress due to the location of the cooling channel. This is due in particular to the fact that the axial force components emanating from the valve via the valve seat surface lie within their effective range Heavy load on the walls of the cooling duct. In order to absorb these forces, the valve seat in this area must be made with large wall thicknesses and in high-quality materials. Both measures lead to a significantly poorer cooling effect at the outlet valve, especially since the high-quality materials have a poorer thermal conductivity.
the object is achieved in that the axial support surface of the valve seat on the shoulder of the stepped part of the receiving bore lies in the direct range of action of the force components extending axially from the valve seat surface by the support force of the valve.
the part of the valve seat which engages in the offset part of the receiving bore in the cylinder head base has, between its axial and radial support surface, an annular space for a coolant which is delimited on the outside by the cylinder head base.
the gas exchange channel 2 is formed on the cylinder side as a receiving bore 3 for a valve seat 4, which merges at its end that runs out toward the cylinder into a part 5 that is offset to a larger diameter.
This part 5, which is set apart from the receiving bore 3, is delimited in the axial direction by a shoulder 6, which lies in a plane running at right angles to the central axis of the receiving bore 3.
a sleeve-shaped valve seat 4 is provided, which extends from the stepped part 5 to close to the other end of the receiving bore 3.
valve seat 4 Located on the valve seat 4 in its upper region is an annular space 7 which is delimited on the outside by the receiving bore 3 and which serves for the flow of a coolant.
the valve seat 4 In the area of the offset part 5 of the receiving bore 3, the valve seat 4 is supported radially via its cylindrical outer surface 8 on an outer wall 9 and axially via a flat annular surface 10 on the shoulder 6. To adequately cool the valve seat 4, the valve seat 4 has in its part 5
annular space 12 which is delimited on the outside by the cylinder head base 1.
the annular space 12 is connected through a channel 13 to the cooling water circuit of the internal combustion engine.
At least two connecting channels 14 for the supply or return of coolant are arranged between the two annular spaces 7 and 12 provided in the valve seat 4.
forces act on the valve seat 4 from the valve 15, which are caused in particular by the combustion pressures acting on the valve disk.
These forces which are shown in the drawing by an arrow 17, are broken down by the 45 ° inclined sealing surface 16 in the valve seat into radial and axial force components according to arrows 18 and 19.
the radial force components are applied to the outer surface of the valve seat 4 on the transmit this surrounding cylinder head base 1 directly, while the axial force components according to arrow 19 are also directly absorbed by the shoulder 6.
bending stresses do not occur in the valve seat 4 in the effective range of the radial or the axial force components according to the arrows 18 or 19.
