Claim 8:
9. A method of trapping particulate matter disposed in a fluid, comprising:
providing a particle trap having a longitudinal axis, wherein the particle trap allows a fluid to flow along the longitudinal axis in a first direction or separately in a second direction, wherein the second direction comprises a direction which is a reverse of the first direction;
flowing a fluid including particulate matter through the particle trap at an initial rate of fluid flow, wherein the flowing comprises the fluid flowing through the particle trap in the first direction;
directing the fluid at least partially through one or more cavities disposed along the longitudinal axis of the particle trap,
wherein each of the one or more cavities comprises a cavity surface comprising one or more apertures and one or more check valves;

trapping at least a portion of the particulate matter in at least one of the one or more cavities when the rate of fluid flow slows or becomes suspended, or the flowing reverses such that the flowing comprises the fluid flowing in the second direction; and
cleaning the one or more cavities as the rate of fluid flow is restored to the initial rate of flow or as the flowing returns to comprising the fluid flowing through the particle trap in the first direction.
