Claim Text:
1. A system for sampling fluid from a top land piston crevice of a reciprocating piston engine, during operation of the engine, comprising: a collector having a receiving end operable to receive sampled fluid from the piston crevice; wherein the collector comprises a housing, a valve, and a shuttle; wherein the housing is an elongated hollow shell having a bore through its length; wherein the bore contains the valve and the shuttle and communicates the sampled fluid from the receiving end of the housing to the valve; wherein the valve is operable to allow the sampled fluid to pass along the bore toward the shuttle when the valve is in an open position; wherein the shuttle is operable to move back and forth within the bore, thereby opening the valve, and to further store sampled fluid within its interior or between at least some of its exterior surface and the interior surface of the housing; and an actuator operable to move the shuttle back and forth within the bore.
