Abstract
Abstract A sealing arrangement within the area of the joint surfaces between cylinder head, inserted cylinder liner with cylinder liner flange and cylinder crankcase of a water-cooled internal combustion engine in which a recessed fit is provided at the cylinder head for the accommodation of the cylinder liner flange; a flat seal is thereby arranged on the joint surface between the cylinder-crankcase and the cylinder head and the flange of the cylinder liner as well as the cylinder head rest on the flat seal; the transmission of the contact pressure onto the cylinder liner flange thereby takes place by direct contact with the cylinder head.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
107 words
A sealing arrangement within the area of the joint surface means between cylinder head, cylinder liner and cylinder-crankcase of an internal combustion engine equipped with inserted cylinder liners provided with a flange, a fitting recess being provided at the cylinder head for accommodating the cylinder liner flange, characterized in that a flat seal means is arranged on the joint surface means between cylinder-crankcase and cylinder head and in that both the flange of the cylinder liner as also the cylinder head rest on the flat seal means, the transmission of the contact pressure onto the cylinder liner flange taking place by direct contact with the cylinder head.
Claim 2
Dependent Claim
107 words
A sealing arrangement within the area of the joint surface means between cylinder head, cylinder liner and cylinder-crankcase of an internal combustion engine equipped with inserted cylinder liners provided with a flange, a fitting recess being provided at the cylinder head for accommodating the cylinder liner flange, characterized in that a flat seal means is arranged on the joint surface means between cylinder-crankcase and cylinder head and in that both the flange of the cylinder liner as also the cylinder head rest on the flat seal means, the transmission of the contact pressure onto the cylinder liner flange taking place by direct contact with the cylinder head.

Claim 8
Dependent Claim
41 words
A sealing arrangement according to claim 5, characterized in that the elastic sealing ring means are fixedly secured in the flat seal means to avoid loss thereof and project beyond the flat seal means on both sides by a slight amount.
Claim 9
Dependent Claim
38 words
A sealing arrangement for a water-cooled internal combustion engine according to claim 1, characterized by the provision of elastic sealing ring means in the flat seal means at the places of liquid passage openings for the cooling liquid.
Claim 10
Dependent Claim
40 words
A sealing arrangement according to claim 8, characterized in that the elastic sealing ring means are fixedly secured in the flat seal means to avoid loss thereof and project the flat seal means on both sides by a slight amount.
Claim 11
Dependent Claim
22 words
A sealing arrangement according to claim 1, wherein said direct contact between said liner means flange and said cylinder head is seal-free.
Claim 12
Dependent Claim
62 words
A sealing arrangement for an internal combustion engine comprising: a cylinder head, a cylinder-crankcase, and cylinder liner means arranged to provide facing joint surfaces, and seal means arranged between the joint surfaces in sealing engagement therewith, wherein a cylinder liner means flange and the cylinder head constitute one of said joint surfaces and the cylinder-crankcase constitutes the other of said joint surfaces.
Claim 13
Dependent Claim
62 words
A sealing arrangement for an internal combustion engine comprising: a cylinder head, a cylinder-crankcase, and cylinder liner means arranged to provide facing joint surfaces, and seal means arranged between the joint surfaces in sealing engagement therewith, wherein a cylinder liner means flange and the cylinder head constitute one of said joint surfaces and the cylinder-crankcase constitutes the other of said joint surfaces.
Claim 14
Dependent Claim
18 words
A sealing arrangement according to claim 10, wherein said flange contacts said cylinder head in a seal-free manner.
Claim 15
Dependent Claim
16 words
A sealing arrangement according to claim 10, wherein said seal means is a single seal means.
Claim 16
Dependent Claim
38 words
A sealing arrangement according to claim 10, wherein said flange and said cylinder head rest on one side of said seal means while said cylinder-crankcase is provided on a side of said seal means opposite said one side.
Claim 17
Dependent Claim
66 words
A sealing arrangement according to claim 14, wherein a height of said flange and a depth of a recess in said cylinder head for receiving said flange are so matched to each other that the surface pressure at the flange, with a predetermined pretensioning of cylinder head bolts, is always larger by a multiple that the surface pressure between the cylinder head and the seal means.
