Abstract:
A thermally insulated container includes a base having a bottom wall and sidewalls, and a lid. A liquid-impermeable and moisture-resistant film overlays the outer surface of the base and sidewalls and can extend inside of the base. The film can be plastic shrink wrap film. The sidewalls of the base can be tapered to allow the containers to be nested in a stacked arrangement.
Abstract:
A cylinder head for an internal combustion engine is shaped and dimensioned to sit above a cylinder on top of a cylinder block so as to define a combustion chamber. The cylinder head includes a cylinder head body having a lower cavity defining a portion of a combustion chamber when the cylinder head is secured to a cylinder block. The cylinder head body also includes an intake port and an exhaust port in fluid communication with the lower cavity, wherein the exhaust port has a generally L-shaped configuration as its extends from an inlet end of the exhaust port to an outlet end of the exhaust port, and the intake port has a generally L-shaped configuration as its extends from an inlet end of the intake port to an outlet end of intake port. The intake port includes an inlet leg, an outlet leg and an inlet elbow therebetween, and as the intake port approaches the inlet elbow, a passageway of the exhaust port bifurcates into adjacent substantially oval passageways.
Abstract:
The lubrication distribution system can be used whenever two chambers are separated by a wall with a source of lubrication in one chamber, a suction source in the other chamber and a pair of pathways between them for transporting oil. The oil distribution system for the internal combustion chamber uses appropriately placed ports and centrifugal force generated by a flywheel to provide lubrication for all moving parts in the engine. Oil is delivered from a sump to the cam chest. The cam chest is separated from the flywheel housing by a wall. A venturi port opening in the wall creates suction in the cam chest by virtue of the centrifugal force created by the flywheel. An air-oil mixture is circulated throughout the cam chest and through the venturi port opening. The oil mixture is circulated through the flywheel housing and returned to the cam chest through a second set of ports between the cam chest and flywheel housing.
Abstract:
The oil pump has a cam support plate attached to the engine block. The support plate has a pressure relief valve. An oil pump body assembly has a pair of gerotors on each side. The gerotors are attached to and driven by a shaft attached to the rear cam.
