Appl. No.:

11/530303

Inventors:

Dean M. Nelson - Waldo WI, US
Jonathan R. Chittenden - Edwards IL, US
Daniel F. Krueger - Sheboygan WI, US

Assignee:

Kohler Co. - Kohler WI

International Classification:

F02M 25/06

US Classification:

123572

Abstract:

An internal breather for removing oil from blow-by in an internal combustion engine is disclosed. The breather includes a breather cover having a breather cover drainback hole. The breather further includes a breather cover seal in sealed engagement with the breather cover, and the breather cover seal includes a breather cover seal drainback hole that is aligned with the breather cover drainback hole to create a drainback passage. A breather chamber is bounded on at least one end by the breather cover and the breather seal. A breather media is positioned within the breather chamber, the breather media for removing an amount of oil from the blow-by. The amount of oil removed from the blow-by can, during operation of the engine, be drawn through the drainback passage so as to exit the breather chamber, at least partially due to gravity, and at least partially using a gearing mechanism that is in operative association with a camshaft of the engine. Advantageously, the gearing mechanism, for example a helical gear, can be strategically positioned in-line with the drainback passage.

International Classification:

F02D 17/04
F02D 33/00
B23P 19/00

Abstract:

A combination lever for a carburetor is an integrated shutoff lever and fuel valve. The combination lever includes a longitudinal portion for a handle and a cylindrical portion including a fuel path for the fuel valve. A carburetor casing is shaped to form a valve chamber and a carburetor chamber. The valve chamber supports the cylindrical portion. A directional cavity formed in the cylindrical portion of the combination lever regulates a flow of fuel to the carburetor chamber according to a rotation of the combination lever. At one position the directional cavity opens the fuel path so that fuel flows into the carburetor chamber. At another position the directional cavity closes the fuel path so that the flow of fuel is blocked. The combination lever may also include an abutment portion to engage a switch for completing an electrical shutoff path to an engine coupled to the carburetor.
