Abstract
A system is set forth for cooling the circulating oil of an air cooled motorcycle engine having an oil pump and a mount for an oil filter, oil from the pump delivered to the filter and from the filter back to the engine for re-circulation. The system includes an engine guard secured to the motorcycle, at least a portion of the guard defining a closed chamber having a supply end and a return end. A diverter disposed between the filter and mount is adapted to direct oil to the chamber supply end, through the chamber for cooling thereof and, from the return end back to the diverter for supply to the filter and return to the engine. An adapter is disposed between the diverter and filter for certain model engines to turn the mount, diverter filter assembly so that the system can be provided for these engines.
Claims16
In an air-cooled motorcycle engine having an oil pump and means for mounting an oil filter, said mounting means directing oil from the pump to the filter and from the filter to the engine, an improvement comprising:
- an engine guard secured to the motorcycle, said engine guard defining a closed chamber having a inlet and a outlet;
- and
- means for diverting oil discharged from the pump to the engine guard inlet for circulation through the chamber and for directing the oil from the engine guard outlet to the filter, said diverting means disposed between said mounting means and said filter, said engine guard providing cooling of the oil circulating therethrough.
A system for cooling oil for an air cooled motorcycle engine having an oil pump, an oil filter and means for mounting the filter to the engine, said mounting means including an opening communicating with the discharge of the pump to supply oil to the filter and a port for receiving oil returning from the filter to the engine, the system comprising:
- a hollow engine guard adapted to be secured to the motorcycle, at least a portion of the hollow of the engine guard defining a closed chamber having a supply end and a return end;
- a diverter adapted to be disposed between said filter and mounting means, said diverter including a first channel to provide communication of oil between said opening and an outlet and a second channel to provide communication of oil between an inlet and said filter;
- and
- a first conduit to communicate oil from the outlet to the chamber at the supply end for circulation of oil therethrough and a second conduit to communicate oil from the chamber at the return end to the inlet for circulation through the filter, said engine guard transferring heat to the environment to cool said oil circulating therethrough.
An improved motorcycle of the type having a frame and an air cooled engine with an oil pump and means for mounting an oil filter, said pump circulating oil through the engine, into the filter and from the filter back to the engine, the improvement comprising:
- an engine guard secured to the frame, at least a portion of the engine guard defining a closed chamber having a supply end and a return end;
- a diverter adapted to be disposed between said filter and mounting means, said diverter including a first channel to provide communication of oil from the pump to an outlet and a second channel to provide communication of oil between an inlet and said filter;
- and
- a first conduit to communicate oil from the outlet to the chamber at the supply end for circulation of oil therethrough and a second conduit to communicate oil from the chamber at the return end to the inlet for circulation through the filter and back to the engine, said engine guard transferring heat to the environment to cool said oil circulating therethrough.
In an air-cooled motorcycle engine having an oil pump and means for mounting an oil filter, said mounting means directing oil from the pump to the filter and from the filter to the engine, an improvement comprising:
- an engine guard secured to the motorcycle, said engine guard defining a closed chamber having a inlet and a outlet;
- means for diverting oil discharged from the pump to the engine guard inlet for circulation through the chamber and for directing the oil from the engine guard outlet to the filter, said diverting means disposed between said mounting means and said filter, said engine guard providing cooling of the oil circulating therethrough;
- and
- an adapter secured at one surface to the diverter and at another surface mounting the filter, said adapter including a bore to communicate oil from the filter to the engine and a channel to communicate oil from said diverter to the filter for filtering thereof and said one and another surfaces disposed to mount the filter at an angle relative to the mount.
