Abstract
An adapter mechanism for use between an engine and an oil cooler manifold, includes a special nut having internal threads for screw-on engagement with an externally threaded engine boss. External threads on the nut mate with threads on a central wall portion of an associated oil cooler manifold to operatively connect the manifold with oil passages in the engine block. Differently dimensioned nuts may be selectively utilized to connect a given manifold with a range of different engines. An annular adapter plate is positioned between the manifold and engine to provide sealed passage connections to or from the manifold passages.
Claims7
An adapter mechanism for coupling an engine oil circulation system to an external oil cooler manifold structure, wherein an engine has an externally threaded hollow boss constituting a first oil passage, an annular land surface concentric with said hollow boss, an annular recess between the hollow boss and the land surface, and a second oil passage connected to said recess, said adapter mechanism comprising:
- a multiple thread surface nut threadable onto the hollow boss to form a threaded mounting surface for said manifold structure,
- said nut having inner threads engageable with the threads on the hollow boss, and outer threads adapted to mesh with internally threaded connector means on said manifold,
- an annular plate sandwiched between the manifold structure and the engine land surface, said annular plate having an outer edge and an inner edge, and
- a flange projecting from said inner edge for piloting the plate to a predetermined position on the land surface.
An adapter mechanism for coupling an engine oil circulation system to an external oil cooler manifold structure, wherein an engine has an externally threaded hollow boss constituting a first oil passage, an annular land surface concentric with said hollow boss, an annular recess between the hollow boss and the land surface, and a second oil passage connected to said recess, said adapter mechanism comprising:
- a multiple thread surface nut threadable onto the hollow boss to form a threaded mounting surface for said manifold structure,
- an annular plate sandwiched between the manifold structure and the engine land surface, said annular plate having an outer edge and an inner edge,
- said annular plate having a stepped manifold structure engagement surface to provide two concentric seating surfaces for engagement with two differently sized manifold structures, and
- a flange projecting from said inner edge for piloting the plate to a predetermined position on the land surface.
An adapter mechanism for coupling an engine oil circulation system to an external oil cooler manifold structure, wherein an engine has an externally threaded hollow boss constituting a first oil passage, an annular land surface concentric with said hollow boss, an annular recess between the hollow boss and the land surface, and a second oil passage connected to said recess, said adapter mechanism comprising:
- a multiple thread surface nut threadable onto the hollow boss to form a threaded mounting surface for said manifold structure,
- a section of the nut outer thread being deformed, whereby the nut has a tight friction fit on a manifold connector means and a loose friction fit on the hollow boss,
- an annular plate sandwiched between the manifold structure and the engine land surface, said annular plate having an outer edge and an inner edge, and
- a flange projecting from said inner edge for piloting the plate to a predetermined position on the land surface.
