The “factory installed” pressure regulator valve of an automotive transmission is replaced by a pressure regulator valve having two separate valve components conjointly movable together in a bore. A protrusion or protuberance extending from the center of one end of one of the valve components defines a fulcrum which abuts against an adjacent end of the other valve component as the two valve components move conjointly and in direct contact with each other within the bore during operation of the pressure regulator valve. Preferably, an opening is provided in a land in one of the valve components to vent hydraulic fluid (transmission oil) to prevent a pressure build-up in the bore which might separate the two valve components from each other during reciprocating movement of the valve components in the bore.
A pressure regulator valve for an automotive transmission, said pressure regulator valve comprising separate first and second valve components, said first valve component having a protuberance defining a fulcrum extending from one end thereof in a direction towards an adjacent end of said second valve component, said first and second valve components being arranged such that the fulcrum of said first valve component directly contacts the adjacent end of said second valve component as said first and second valve components reciprocally move in a valve bore.
An hydraulic circuit for an automotive transmission, said hydraulic circuit having a pressure regulator valve, said pressure regulator valve comprising separate first and second valve components, said first valve component having a protuberance defining a fulcrum extending from one end thereof in a direction towards an adjacent end of said second valve component, said first and second valve components being arranged such that the fulcrum of said first valve component directly contacts the adjacent end of said second valve component as said first and second valve components reciprocally move in a valve bore.
A method of modifying an automotive transmission having a pressure regulator valve formed from a single valve component, said method comprising the steps of:
