Monitoring and regulating device for a fluid such as engine oil

An engine oil regulating device comprising:

• a housing in fluid communication with an engine crankcase;
• a float chamber defined within said housing;
• first and second floats in said float chamber;
• an electro-mechanical safety shutdown/alarm switch responsive to said second float in said float chamber and signalling a safety shutdown/alarm condition of an engine;
• a valve located within said float chamber responsive to said first float and regulating an oil level within said float chamber;
• and
• an adjustable test knob connected to a test arm positionable against a float arm for forcing actuation of said electro-mechanical safety shutdown/alarm switch.

A fluid level regulating and signal sending device comprising:

• a housing in fluid communication with and remote from a monitored fluid reservoir, and exhibiting a fluid chamber and a fluid inlet;
• a first sensor responsive to a fluid level in said fluid chamber;
• a second sensor independent of said first sensor comprising at least a float movably mounted in said fluid chamber responsive to said fluid level in said fluid chamber;
• a fluid level visual indicator in fluid communication with said housing;
• a closure valve located at said fluid inlet and responsive to said first sensor;
• a mechanically actuated safety shutdown/alarm element responsive to said float detecting a fluid level outside a predetermined range, said safety shutdown element including signal sending means for sending a shutdown/alarm signal to a remote location.

An engine oil regulating device comprising:

• a housing in fluid communication with an engine crankcase;
• a float chamber defined within said housing;
• an electro-mechanical safety shutdown/alarm switch connected to said housing for causing a safety shutdown of an engine;
• a float system located within said float chamber for actuating said safety shutdown/alarm switch and for regulating an oil level within said float chamber;
• said float system includes at least an oil level regulating float connected to an inlet valve to admit oil to said crankcase through said housing when and only when oil level in said housing falls below a first predetermined level, and a safety shutdown/alarm float independent of said oil level regulating float connected to said electro-mechanical safety shutdown switch when oil level in said housing falls below a second predetermined level;
• and
• a test actuator mechanism configured to manually actuate said electro-mechanical switch independent of an oil level in said housing.
