摘要： A valve assembly includes a housing and a float. The housing is constructed and arranged to inhibit movement of the float between a resting position to a position where it is situated in its valve seat, unless a selected liquid volume within the valve housing is attained. In one embodiment, a series of projection members or rings creates a tortuous path, such that there is no clear path for the float to reach the valve seat. In another embodiment, vacuum pressure is created between the float and its cup support. Still other embodiments utilize magnets, springs, linkages, and bent wires. Methods for preventing liquid ingestion into an engine through an air intake are also provided.

摘要： A filter-cleaning apparatus utilizes pulsed air to remove matter collected on a first surface of a filter. Reverse flow loosens the material which is collected in a hopper on the upstream side of the filter. The collected matter may then be combusted in the hopper so that the amount of material collected is minimized. The pulses are directed at the filter with a controlled shape and time to optimize reverse pulsing. Pulsing occurs while the thermal exhaust flow continues so that operation of the engine is not interrupted. A number of valves may be utilized to clean one or more filters.
