Deadline safety valve for crankcase emission control system

摘要

(57) Abstract In the closed type crankcase discharge control system (10) for the internal combustion engine (12), the first end cap (96) which is in one end of interchangeable filter element (73) and the filter ring (94) which possess the filter ring (94), in the other end of the filter ring the oil catcher container which is defined by the second end cap (98), in the saucer (128) for the valve of the cup shape which is locked to the second end cap, and the engine on stream the fact that the blow-by gas escapes directly is obstructed to filter element,At the same time, the check valve (140) inside the saucer for the valve in order to try to be able to collect the oil which flowed out from the oil catcher container while idling or stopping of the engine is included. The deadline valve (160 and 200), oil passing the discharge control system, it is provided in order to prevent the fact that it flows to the engine. The deadline valve includes the cylindrical float component (162) of the support body (164) and the seal functional (166) attachment. Here, the guide component (169) is included in the body. Furthermore, the float component even with the ball valve (214 and 272) is possible. The float component (162) to float with the fuel level inside the housing, be able to seal the seat fluid, outflow to the engine of oil is prevented. Valve in filter element (73), to the central hanger tube (184) of the housing, or, can install in the entrance of the housing or the joint (268 and 270) of the exit. Providing support structure (174 and 218), it maintains this float component in proper direction. Furthermore, the deadline valve providing the pressure by-pass valve (230) high-level, it is possible to let escape the systematic pressure when closing the deadline valve.
