Abstract: A head, for an internal combustion engine, is provided, the head using at least one plate to control the filling and emptying of the combustion chamber. The plate may be placed so that the movement of the plate may open or close the intake and/or exhaust ports. The timing of the opening and closing of the port can be controlled by a partial cutout in the plate.

Abstract: A system for preventing overflow in a storage tank which is fillable via a nozzle includes a nozzle receiver configured to fit within a fill passage of a storage tank. The system further includes at least one seal disposed in the nozzle receiver configured to seal the nozzle within the nozzle receiver. The system has a first passage and a second passage. The first passage is configured to fit at least partially within the fill passage of a storage tank and receive at least a portion of a flow of liquid from the nozzle. The second passage is in communication with the first passage. The system also includes a valve having a first position that directs liquid to flow through the first passage and a second position that directs liquid to flow through the second passage.

Abstract: A system, for preventing overflow in a tank, fillable via a nozzle, includes a fill passage connecting the storage tank to an external atmosphere. An adjacent passage has a lower end disposed at a predetermined level within the storage tank and an upper end communicating with a hole in the fill passage. A vent passage connects the adjacent passage to the external atmosphere, and a valve is disposed in the vent passage, permitting the flow of air through the vent passage and prohibiting the flow of liquid through the vent passage.

Abstract: A system, for preventing overflow in a tank, fillable via a nozzle, includes a lower passage and an upper passage. An upper end of the lower passage receives a portion of fuel flow from the nozzle, and a lower end is in communication with the tank. The upper passage has a lower end in communication with an interior of the lower passage and an upper end in communication with a hole in the nozzle. A valve connects to the lower passage and has a fill position and a stop position. When a level of liquid in the tank is below a predetermined level, the valve is in the fill position and fuel is permitted to flow out the lower end of the lower passage. When the level of liquid in the tank is at or above the predetermined level, the valve is in the stop position and blocks the flow of fuel out of the lower end of the lower passage.

Abstract: A system for preventing overflow in a storage tank which is fillable via a nozzle inserted in a fill passage includes a nozzle stop such that when an end of the nozzle contacts the nozzle stop, the nozzle is in a fill position. The system also includes a sealing device within the fill passage, which forms an inner sealing space via a first seal around the nozzle below a hole in the nozzle and a second seal around the nozzle above the hole in the nozzle. An airtight passage connects the inner sealing space to an interior of the storage tank. The system may also include a venting system including a tank vent passage between the storage tank and an end of the fill passage and an atmospheric vent passage between the tank vent passage and the external atmosphere.
