Abstract
Abstract A liquid-cooled reciprocable piston internal combustion engine with a crank-case extending into the region of the foot portion of a cylinder while adjacent said crank-case there is provided a jacket surrounding said cylinder and forming therewith a first cooling fluid receiving chamber, while the cylinder head and said cylinder together form a structural unit which is inserted between and rests against the cylinder head and the crank-case, said first cooling fluid receiving chamber means communicating through passage means with second cooling fluid receiving chamber means in the cylinder head.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
190 words
A convertible gas-liquid-cooled reciprocable piston internal combustion engine, which incluDes in combination: a cylinder having a cylinder bottom at one end and being open at the other end, a crank-case extending around the open end portion of said cylinder, separable jacket means mounted on said crank-case and surrounding said cylinder so as to form therewith first cooling chamber means adapted to receive and pass cooling fluid therethrough, a cylinder head having second cooling chamber means therein for communication with a cooling circuit and being connected to that end of said cylinder which comprises said cylinder bottom, said cylinder head and said cylinder forming a structural unit securely joined with respect to each other, and conduit means extending in radial direction with regard to the axis of the cylinder and thereby establishing communication between said first cooling chamber means and said second cooling chamber means, said jacket means resting both against said crankcase and said structural unit formed by said cylinder head and said cylinder, said jacket means and first cooling chamber means extending beyond the cylinder bottom, said jacket means being clamped axially between said cylinder head and said crank-case.
Claim 2
Dependent Claim
190 words
A convertible gas-liquid-cooled reciprocable piston internal combustion engine, which incluDes in combination: a cylinder having a cylinder bottom at one end and being open at the other end, a crank-case extending around the open end portion of said cylinder, separable jacket means mounted on said crank-case and surrounding said cylinder so as to form therewith first cooling chamber means adapted to receive and pass cooling fluid therethrough, a cylinder head having second cooling chamber means therein for communication with a cooling circuit and being connected to that end of said cylinder which comprises said cylinder bottom, said cylinder head and said cylinder forming a structural unit securely joined with respect to each other, and conduit means extending in radial direction with regard to the axis of the cylinder and thereby establishing communication between said first cooling chamber means and said second cooling chamber means, said jacket means resting both against said crankcase and said structural unit formed by said cylinder head and said cylinder, said jacket means and first cooling chamber means extending beyond the cylinder bottom, said jacket means being clamped axially between said cylinder head and said crank-case.
Claim 3
Dependent Claim
28 words
An internal combustion engine in combination according to claim 1, in which said conduit means are arranged mainly over a limited portion of the circumference of said cylinder.
Claim 4
Dependent Claim
64 words
An internal combustion engine in combination according to claim 2, in which said cylinder head is open along its circumference within the region of said conduit means, and in which an open portion along the circumference of said cylinder head is over a section of said circumference covered above by said jacket means, said jacket means being centered by and above said cylinder head.
Claim 5
Dependent Claim
58 words
An internal combustion engine in combination according to claim 3, in which said cylinder head includes nozzle holder means, and which comprises nozzle means mounted in said nozzle holder means, and passage means passing around said nozzle holder means and communicating with said first cooling chamber means for conveying cooling fluid uniformly distributed around said nozzle holder means.
Claim 6
Dependent Claim
41 words
An internal combustion engine in combination according to claim 4, in which said cylinder head is provided with web means having a passage therein communicating directly with said second cooling chamber means and the outer wall of said nozzle holder means.
Claim 7
Dependent Claim
29 words
An internal combustion engine in combination according to claim 4, in which said separable jacket means is divided along a plane transverse to the axis of the adjacent cylinder.
Claim 8
Dependent Claim
24 words
An internal combustion engine in combination according to claim 6, in which the sections of said jacket means are clamped securely to each other.
Claim 9
Dependent Claim
51 words
An internal combustion engine in combination according to claim 7, which includes cool water pump means threadedly connected to said jacket means at an end face of said engine, and in which the spiral housing of said cool water pump means together with said jacket means forms a single integral piece.
