Abstract
A lubricating oil supply system has a pump for automatically supplying lubricating oil from an oil tank to a crankcase of an engine through a passage. A bimetallic strip is cantilevered on a wall of the passage. The bimetallic strip is provided so as to reduce the cross-sectional area of the passage at the bimetallic strip when the temperature of the strip rises and to increase the cross-sectional area when the temperature lowers.
Claims14
A lubricating oil supply system for an engine having a pump for automatically supplying lubricating oil from an oil tank to a crankcase of the engine through a passage, comprising:
- a control member comprising a bimetallic strip cantilevered on a wall of the passage so as to reduce the cross-sectional area of the passage at the control member when the temperature of the control member rises and to increase the cross-sectional area at the control member when the temperature lowers;
- and
- an electric circuit comprising said strip, a pair of contacts connected in said circuit, a warning lamp, and a battery, in series;
- and
- said strip engages respective of said contacts when the strip bends with a change of temperature to respective predetermined upper limit and lower limit temperatures.
