ABSTRACT:
A swash plate mechanism, for coverting linear motion into notary motion and vice versa is disclosed, which overcomes the main difficulties with older arrangements of swash plate drives. These are the high friction of most drives or the high complexity of efforts to overcome the friction effects. The mechanism of this invention permits the application of low friction bearings like ball bearings, in all of the rotating or sliding joints of the machine, except for the pistons, and their cylinders. The mechanisms described can be used in engines or in pumps with equal ease. The swash plate system disclosed, for example, has two spaced swash plates, rotating on a common shaft. A driving plate, which does not rotate, is positioned-between the swash plates and contacts each of the swash plates via ball or roller bearings. When the machine is used to convert the lateral motion of elements, like pistons, to rotary motion of an engine shaft, the pistons are coupled to the drive plate and make the drive plate wobble so as to cause the swash plates to rotate the shaft. When the machine is used to covert rotary motion to linear motion, the prime mover rotates the shaft causing the swash plates to wobble the plate between there which, in turn, causes the pistons or other elements of the total machine to move laterally.
