Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
108 words
A spacer deck for an engine block having a top surface and at least one cylinder bore opening at the top surface, the deck comprising a plate adapted for seating on the top surface, the plate being formed with an aperture positioned coaxially with the cylinder bore but having a smaller diameter than the cylinder bore, the aperture being adapted to encircle a cylinder liner and provide the sole support for the cylinder liner which projects into the cylinder bore, a spacer plate being mounted on said plate, the spacer plate surrounding a flange on the cylinder liner and being of a lesser thickness than the liner flange.
Claim 2
Dependent Claim
108 words
A spacer deck for an engine block having a top surface and at least one cylinder bore opening at the top surface, the deck comprising a plate adapted for seating on the top surface, the plate being formed with an aperture positioned coaxially with the cylinder bore but having a smaller diameter than the cylinder bore, the aperture being adapted to encircle a cylinder liner and provide the sole support for the cylinder liner which projects into the cylinder bore, a spacer plate being mounted on said plate, the spacer plate surrounding a flange on the cylinder liner and being of a lesser thickness than the liner flange.
Claim 3
Dependent Claim
53 words
A seal mounted in a groove of the spaCer plate described in claim 1, the groove situated adjacent a liner flange receiving aperture in the spacer plate so that the seal bears against the intersection of the cylinder flange and a cylinder head lower deck to seal the combustion chamber within the cylinder.
Claim 4
Dependent Claim
137 words
In an internal combustion engine having a cylinder block with a top deck and a cylinder head with a lower deck, at least one bore in the cylinder block receiving a cylinder liner therein, the cylinder liner having a flange thereon which extends above the top deck of the block and to the lower deck of the head means situated on the top deck of the block supporting the liner flange in cantilever fashion within the bore, the supporting means being a relatively resilient member, a spacer means mounted on the supporting means and surrounding, but being of lesser thickness than the liner flange, and means fixing the cylinder head to the cylinder block so that the resilient supporting member retains the liner flange in abutment with the lower deck of the head with a predetermined force.
Claim 5
Dependent Claim
137 words
In an internal combustion engine having a cylinder block with a top deck and a cylinder head with a lower deck, at least one bore in the cylinder block receiving a cylinder liner therein, the cylinder liner having a flange thereon which extends above the top deck of the block and to the lower deck of the head means situated on the top deck of the block supporting the liner flange in cantilever fashion within the bore, the supporting means being a relatively resilient member, a spacer means mounted on the supporting means and surrounding, but being of lesser thickness than the liner flange, and means fixing the cylinder head to the cylinder block so that the resilient supporting member retains the liner flange in abutment with the lower deck of the head with a predetermined force.
Claim 6
Dependent Claim
28 words
The engine of claim 3 including sealing means mounted in the spacing means for sealing the intersection of the lower deck of the block and the liner flange.
