Abstract
An engine oil regulating device may monitor and regulate a fluid level for stationary engines or compressors for gravity feed and pressurized oil applications. Oil may be received in a float chamber that may have a safety shutdown float and an oil level regulating float. The engine oil regulating device may also include a safety shutdown mechanism to actuate an alarm and/or a shutdown switch such as an ignition cut-off switch. The safety shutdown mechanism may be configured as a single switch or a plurality of switches. A two switch safety shutdown mechanism may utilize a side-by-side layout or a stacked layout. The safety shutdown mechanism may include a high-low level shutdown, low level shutdown only, or high level shutdown only. A testing mechanism such as a rotatable test knob assembly may be provided to test the safety shutdown mechanism. An engine oil level adjusting mechanism such as an adjustable threaded thumb valve orifice member may also be provided. The engine oil regulating device may also include a signal sending unit for sending a signal to a place away from the remote location. The signal may indicate an alarm due to an unsafe high and/or low fluid level without a shutdown, a normal fluid level, a safety shutdown due to an unsafe high and/or low fluid level, or a testing signal.
