Abstract: Lubricating oil pumps for internal combustion engines have hitherto had individual drive means such as a pair of skew gears. To simplify and cheapen the pump drive means, the pump is of the internal gear type and is driven by and housed within an idler gear driveably connecting the crankshaft to the camshaft. The pump body is rigidly secured to the engine and has a cylindrical periphery on which the idler gear is journalled, and the externally-toothed inner gear of the pump is driveably connected to the idler gear by a coupling sleeve.

Abstract: A source of gas pressure from an internal combustion engine is made available by tapping off the exhaust products within the combustion chamber, preferably just prior to exhausting the gas out of the engine. A pressure tap fitting communicates with the combustion chamber through the cylinder wall. The opening into the combustion chamber is closed off during most of the stroke of the engine by the skirt of the piston. As the piston, during the power stroke of the engine, is driven down the cylinder wall, the crown of the piston eventually clears the opening in the pressure tap. The exhaust gas, under very high pressure, enters the tap just prior to dumping the exhaust gas through the exhaust ports of the engine. Thus, a useful source of pressure is derived from the engine without affecting the operating efficiency of the engine.

Abstract: An internal combustion engine, which has soundproofing cowling, uses the space between the sidewalls of the cylinder block and the cowling to provide a reservoir for a liquid lubricant media. A cover cap is provided over the fuel injection and valve timing mechanisms, and the space between the cover cap and the cowling, which is over the top of the cylinder head, provides a chamber for receiving coolant from the engine cooling system. The large surface area of the cowling along the sides of the cylinder block accommodates the transfer of heat from the lubricant to the atmosphere. In addition both the lubricant and the coolant serve as sound deadening medias in the sidewall reservoirs and in the overhead chamber.
