ABSTRACT:
The wobble plate engine mechanism includes a cylinder block and mainshaft; a drive hub obliquely mounted for rotation with the mainshaft; a wobble plate rotatable around the hub; cylinders spaced around the mainshaft; and a piston moveable in each cylinder and couple to arms of the wobble plate. Piston and arm couplings comprises a cross-head reciprocable in a piston bore and a gudgeon pin moveable end-wise in a cross-head bore; the cross-head bore and ends of the pin defining cavities so lubricant access, under some operating conditions, dampens that end-wise movement. Means for shifting the wobble plate axis along the mainshaft includes a drawing member coupled to the mainshaft and rotatable on the block to draw the mainshaft, a rotatable actuator shaft and a drive train between the drawing member and actuator shaft. Means for varying the drive hub angle is pivotally connected to the hub and mainshaft on respective sides of the mainshaft. Also, diagonally opposed weights on respective sides of the hub are balanced and offset so their centrifugal force is neutralized, to produce a couple opposite to an out of balance couple from piston and wobble plate motion.
