Reversible volume oil impeller pump with mechanical governor

A fluid pump comprising a pump assembly generating a volume of fluid flow from a reservoir, said pump assembly being powered by an input drive;

• and a control valve disposed between said pump assembly and an outflow;
• said control valve alters a portion of said volume directed to said outflow when a speed of said input drive is changed;
• a diversion, said control valve alters a portion of said volume directed to said diversion in response to said portion directed to said outflow;
• an outflow passage extending through said control valve and a diversion passage extending through said control valve, said outflow passage being disposed to connect said pump assembly to said outflow and said diversion passage being disposed to connect said pump to said diversion;
• wherein said control valve alters said outflow passage connection and said diversion passage connection thereby proportionately altering said portions directed to said outflow and said diversion;
• said pump assembly generates said volume of fluid flow regardless of a rotational direction of said drive input;
• and
• said pump assembly is an impeller pump assembly.
