Connecting rod and piston for an oil-less pneumatic motor
First Claim
1. An oil-less pneumatic motor comprising a connecting rod and piston assembly;
- said connecting rod comprising at least two ends, connected to each other by a connecting member of a predetermined length;
said at least two ends comprising a piston end and a crankshaft end;
said piston end being distant said crankshaft end;
said piston comprising a cylinder end and a connecting rod piston end receiving end, wherein said connecting rod piston end receiving end matingly engages said connecting rod piston end;
said piston end being substantially ball shaped and said crankshaft end shaped for engagement with a crankshaft wherein said crankshaft end is arcuate shape with a raised arcuate edge of a radial thickness greater than a greatest thickness of said connecting member in a direction of the rotational axis of the crankshaft for use with a combination retaining ring/thrust washer and said connecting rod piston end receiving end further comprises a piston seal, for sealing said connecting rod piston end in said piston;
said connecting rod piston end receiving end being substantially socket shaped for matingly receiving said ball shaped piston end;
said connecting rod and piston assembly in an oil-less pneumatic motor driving paint mixing paddles.
