Abstract

See full text

Exemplary connecting rods and piston assemblies are disclosed. An exemplary connecting rod includes a shaft extending between a piston pin end and a crankshaft pin end, where the piston pin end defines a pin bore opening. The shaft defines a lubrication passage. The connecting rod further includes a piston pin bore surface extending about an inner circumference of the pin bore opening, and the lubrication passage extends through the shaft from the crankshaft pin end to the pin bore opening. The connecting rod may further include a valve received within the opening, e.g., a one-way valve, that is configured to permit a fluid to flow through the valve toward the piston pin end while restricting flow of the fluid through the valve toward the crankshaft pin end.
