US Patent:

6526927, Mar 4, 2003

Filed:

Oct 3, 2000

Appl. No.:

09/678627

Inventors:

Dennis C. Palmer - Redondo Beach CA 92007

International Classification:

F02B 7518

US Classification:

123 561

Abstract:

The improved internal combustion engine of the cam drive axial piston type includes modification to the drive shaft, bearings and other internal elements to facilitate the flow of oil and lubricants to engine parts. The cooling system is modified to allow coolant flow directly to the engine block and head assembly and to control flow through the engine and radiator to reduce hot spots. The valves and valve crown structure have been modified for ease of assembly and reliability of the roller valve lifter and valve interface. Use of alternate fuel supply systems which eliminate the need for a valve train are also accommodated. The drive shaft and engine have been modified to allow the mounting of a variety of aircraft propellers using a hub as well as mounting a flywheel for reduced start motor stress.

Abstract:

The improved internal combustion engine of the cam drive axial piston type includes modification to the drive shaft, bearings and other internal elements to facilitate the flow of oil and lubricants to engine parts. The cooling system is modified to allow coolant flow directly to the engine block and head assembly simultaneously and to control flow through the engine and radiator to reduce hot spots. The valves and valve crown structure have been modified for ease of assembly and reliability of the roller valve lifter and valve interface. Use of alternate fuel supply systems which eliminate the need for a valve train are also accommodated.

Filed:

Appl. No.:

6/459765

International Classification:

F02B 2528

US Classification:

123 58R

Abstract:

An internal combustion engine in which first and second elongate blocks of identical structure are axially aligned and held in longitudinally spaced relationship by a generally cylindrical connector. The first and second blocks cooperate to define a number of axially aligned cylinders, each of which has a double ended piston slidably mounted therein, and each of which piston supports a pair of cam engaging members. A drive shaft is rotatably supported in the first and second blocks, which drive shaft supports a force receiving cam that is engaged by the pairs of members on the pistons, with the cam situated within the confines of the connector. First and second circumferentially extending fuel intake chambers are defined in the first and second blocks, with each being fed fuel from opposite sides thereof, and force being sequentially applied to the pistons by exploding a fuel charge in first one end of each cylinder and then the opposite end thereof, and the pistons as they move in response to the explosion of the fuel charges imparting rotary motion of the cam to rotate the drive shaft. Coolant is discharged into opposite sides of the coolant chamber to more effectively cool the engine. Accessories are preferably disposed in a housing that is interchangeable with a forwardly disposed bullet nose shaped valve cover through which the drive shaft extends to a power take off.
