Abstract:
A compressor ( 20 ) has a case ( 22 ) and a crankshaft ( 38 ). The case has a number of cylinders ( 30 - 32 ). For each of the cylinders, the compressor includes a piston ( 34 ) mounted for reciprocal movement at least partially within the cylinder. A connecting rod ( 36 ) couples each piston to the crankshaft. A pin ( 44 ) couples each connecting rod to the associated piston. Each pin has first ( 52 ) and second ( 53 ) end portions mounted to first ( 56 ) and second ( 57 ) receiving portions of the associated piston and a central portion ( 48 ) engaging the associated connecting rod. For each of the pistons a pair of first and second at least partially non-metallic plugs have respective stems received in the pin first and second end portions and respective heads facing a wall surface of the associated cylinder.

Claim (Index 1):
A method for using a compressor ( 20 ), the compressor comprising:\n a case ( 22 ) having a plurality of cylinders ( 30 - 32 ); a crankshaft ( 38 ) mounted for rotation about an axis ( 500 ); a motor ( 24 ) for driving rotation of the crankshaft; and for each of said cylinders:\n a piston ( 34 ) mounted for reciprocal movement at least partially within the cylinder; \n a connecting rod ( 36 ) coupling the piston to the crankshaft; \n a pin ( 44 ) coupling the connecting rod to the piston, the pin having: first ( 52 ) and second ( 53 ) end portions mounted in first ( 56 ) and second ( 57 ) receiving portions of the piston; and a central portion ( 48 ) engaging the connecting rod; and \n a pair of first and second at least partially non-metallic plugs ( 80 ) having respective stems ( 81 ) received in the pin first and second end portions and respective heads ( 83 ) each having a surface ( 84 ) facing a wall surface ( 70 ) of the associated cylinder, \n the method comprising:\n driving the crankshaft with the motor; and \n for at least one of the non-metallic plugs, venting an interior of the associated pin to a space between the head of said plug and the wall surface of the associated cylinder.
