Twin lubrication tank filling system
First Claim
Patent Images
1. A twin lubrication oil tank filling system with a single oil fill port that prevents overfilling of both a primary oil tank and a secondary oil tank, comprising:
- a gravity fill system comprising an oil diverter that directs lubrication oil primarily into the secondary oil tank;
a float valve for the secondary oil tank to close oil flow into the secondary tank when the lubrication oil reaches a full level in the secondary tank and causes additional oil flow to pour into the primary oil tank; and
a float valve for the primary oil tank to close oil flow into the secondary oil tank when the lubrication oil reaches a full level in the primary oil tank.

Abstract
A twin lubrication oil tank filling system with a single oil fill port that prevents overfilling of both a primary oil tank and a secondary oil with a gravity fill system by directing oil primarily into the secondary oil tank by means of a special oil diverter, a float valve for the secondary oil tank that closes when the oil level in the secondary tank reaches a full level to cause additional oil flow to pour into the primary oil tank and a float valve for the primary oil tank that closes when the oil level in the primary tank reaches a full level.

11. A twin lubrication oil tank filling system with a single oil fill port that prevents overfilling of both a primary oil tank and a secondary oil tank, comprising:
-
a gravity fill system comprising an oil inlet with an oil diverter that directs lubrication oil primarily into the secondary oil tank and an oil chamber between the oil inlet and the primary and secondary oil tanks for retaining excess lubrication oil poured into the oil inlet;
an external float valve for the secondary oil tank to close oil flow into the secondary tank when the lubrication oil reaches a full level in the secondary tank and causes additional oil flow to pour through an oil chamber into the primary oil tank; and
an external float valve for the primary oil tank to close oil flow into the secondary tank when the lubrication oil reaches a full level in the primary oil tank. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. An external float valve, comprising:
-
a generally cylindrical support member comprising at least one aperture along an upper end of the support member that communicates with an inlet port of the float valve; and
a generally annular external float that slides along the support member, wherein the external float covers the support member aperture as it rises toward the float valve inlet port to shut the float valve. - View Dependent Claims (19, 20, 21, 22, 23)

24. An external float valve, comprising:
-
a mounting flange on an upper end of the float valve;
an inlet port for the float valve that passes through the mounting flange;
a generally cylindrical support member comprising at least one aperture along an upper end of the support member that communicates with the inlet port of the float valve and a float stop that protrudes form a lower end of the support member; and
a generally annular external float that slides along the support member between the mounting flange and the float stop, wherein the external float covers the support member aperture as it rises toward the float valve inlet port to shut the float valve. - View Dependent Claims (25, 26)
