Claim 11:
12. A piston mechanism comprising: a cylinder; a piston positioned and located within the cylinder, the piston having an intake side portion and an exhaust side portion; a spray jet device including: a main body portion having a front surface and a rear surface positioned and located on opposing sides of the main body portion; a main protrusion extending outwardly from the front surface in a direction substantially perpendicular to the front surface or the rear surface; a first orifice and a second orifice positioned and located on the main protrusion; a reservoir positioned and located on the rear surface of the main body portion, the reservoir configured to receive the fluid conveyed by the oil supply system; a channel extending along the rear surface of the main body portion, the channel configured to convey the fluid received by the reservoir; and a fluid passageway fluidly coupling the channel to the first orifice and the second orifice to convey fluid from the channel to the first orifice and the second orifice, the fluid passageway extending through the main body portion and the main protrusion in a direction substantially perpendicular to the front surface and the rear surface; an oil supply system configured to convey a fluid to the rear surface of the spray jet device; wherein the piston is movable between a top-dead-center position and a bottom-dead-center position; wherein when the piston is in the top-dead-center position, the first orifice is directed generally at the exhaust side portion of the piston; wherein when the piston is in the top-dead-center position, the second orifice is directed generally at the intake side portion of the piston.
