摘要： 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.

摘要： A reciprocating piston rotary internal combustion engine; comprising a non-rotating circular cylinder engine block containing a rotor on which piston reciprocate at right angles to the direction of centrifugal force, and parallel with the rotor, and at right angles to the direction of rotation of the rotor. These pistons form three sides of the combustion chamber and the combustion chamber ignition blocks, which are built on the rotor along with rotor form two more sides, finally the cylinder forms the sixth side. Compression and decompression is affected by cams on front and back plates guiding pistons by means of cam followers built into the pistons. By altering cams one can produce variable delays (pauses) between the strokes of the combustion cycle or change the number of strokes in a given combustion cycle. The rotor can have the blanks recessed to allow for counterbalances to be inserted, and pistons can have guide rails added to take the counterbalances.

摘要： The disposable cutting head is basically a four element clip together assembly with a base, lower and upper cutting blades, and spring. The base serves as the support for the entire assembly and incorporates the attachment elements for retention to a clipper. The spring holds the elements together, forces the cutting blades together and includes the runner under which the upper blade slides. The entire assembly is such that the head assembly with blades is of the disposable type, but uses metal blades. If desired the blades alone may be disposed and the head assembly reused; however, the structure is not intended for long wear and use. The head and blades are constructed such that the common problems encountered with existing removable/disposable heads and blades as for example heat retention in the blades and head and the catching and pulling of hair are minimized. Use with clipper comb elements is also accommodated.

摘要： An engine structure and mechanism that operates on various combustion processes in a two-stroke-cycle without supplemental cooling or lubrication comprises an axial assembly of cylindrical modules and twin, double-harmonic cams that operate with opposed pistons in each cylinder through fully captured rolling contact bearings. The opposed pistons are double-acting, performing a two-stroke engine power cycle on facing ends and induction and scavenge air compression on their outside ends, all within the same cylinder bore. The engine includes a novel intake/exhaust valve configuration, a novel combustion chamber configuration and a novel external piston rod alignment structure comprising a cam follower assembly including a pair of needle roller bearings riding in longitudinal grooves machined in the cam follower body.

The opposed pistons are double-acting, performing a two-stroke engine power cycle on facing ends and induction and scavenge air compression on their outside ends, all within the same cylinder bore. The engine includes a control system which utilizes twin barrel cams with adjustable axial and angular positions enabling independent compression ratio and port phasing variation during operation. The engine control system comprises one or more electrohydraulic servos to set and maintain the axial and angular relationships of the cams either at extreme positions or controlled to particular positions and schedules thereof utilizing instantaneous piston position feedback information.

摘要： The novel, Compact and Non Vibrating Endothermic Engine (CoNVEE) is an internal combustion engine with reciprocating motion of the pistons inside one cylinder. The “CoNVEE” has the mechanism for the transformation of the axial reciprocating motion of the pistons into rotational motion of the motor shaft.Its innovative architecture makes the engine more compact, given the same delivered power, with respect to the current state of the art. The CoNVEE core occupies a very reduced volume, with a very limited number of moving parts which act in perfect anti-symmetry, compensating all inertia forces developed. The CoNVEE may be conveniently used with any type of propulsion fuel and, particularly, for those applications which require high power density and low vibration in the motor.
