Abstract: Accordingly, the reader will see that this invention is a fuel injection pump which uses an opposed pair of springs acting in parallel to affect the movement of a piston used to pump fuel. Engine pressure pulses, preferably from an engine cylinder, apply a force on the piston and the springs affect the piston's movement to affect the quantity of fuel injected. The spring rates of the springs and their pre-load, or compression, can be adjusted to affect the fuel injection quantity. Proper selection of these spring rates and compressions allows the user to change the pump's specific output and shape this output as a function of engine torque.

Abstract: A temperature compensator for a pressure splitter control chamber has two members which have different thermal expansion rates, and the dimensional changes in these two members caused by temperature change affect the pressure inside the control chamber. The compensator is normally designed so that the control chamber pressure is essentially constant with temperature change, but can be designed to increase or decrease the effect of temperature change on the pressure. This temperature compensator is especially useful in a control chamber used with a pressure splitter which is used as a carburetor compensator. The resulting temperature compensated control chamber allows the pressure splitter to easily be set for use with carburetors jetted for different base altitudes.

Abstract: This invention is an effective engine induction valve which provides a decrease in engine blowback while maintaining engine power. This valve uses a moveable member made from a heat-setting material, this member being bent into an elliptical curve when the member is in the closed position. This elliptical curve has an included angle at the edge of the member which opens toward the engine, this orientation being beneficial in reducing blowback. Using springs to limit the force attaching the moveable member to the valve body prevents unwanted buckling of this member when exposed to elevated temperature and fuel. An embodiment is described which provides a valve with a uniform frequency response at various operating conditions, especially different temperatures.

Abstract: This invention provides a low cost, easily installed means of supplying supplemental fuel to an engine for the purpose of cold starting and enrichment, which also functions as a means for manual operator adjustment of low speed fuel flow. This system is easily adjusted by the operator while driving, requiring only one adjustment for a multi-cylinder engine. This system reduces the fuel delivery imbalance caused by the phase relationships of the fuel pressure pulses and the pressure pulses existing at the outlets of its fuel delivery orifices by using orifices of different areas.

Abstract: An atomizer for a liquid delivered to an internal combustion engine uses a nozzle positioned such that a substantial portion of the liquid which exits the nozzle will come in contact with the moveable member of an engine induction tract one-way valve. This one-way valve is preferably a reed valve, the moveable member being a reed. The reed or other moveable member has a rapid movement in response to engine operation. When the liquid comes in contact with the rapidly moving reed or other moveable member, it is broken into a mist of relatively fine droplet size. This invention is ideally suited when the liquid is a lubricating oil being delivered to an engine wherein there is minimal fuel in its induction tract or crankcase to thin and spread the lubricating oil to its necessary locations in the engine. It is also useful when the liquid is a fuel, breaking the fuel into smaller droplet size which is more suitable for combustion.

Abstract: A fitting is installed on the vent system of a carburetor to shield the last opening of the vent system from dynamic pressures caused by wind currents around this opening. This fitting in its simplest form is a plastic tubing "T", which is installed in the end of the vent tubing of the carburetor. It has been found that this fitting is effective in reducing the dynamic pressure effects on the carburetor internal reference pressure. It has also been found that a "T" having a larger diameter cross hole than perpendicular hole is more effective in reducing the dynamic pressure effects on carburetor reference pressure.

Abstract: An internal vent system contains a pressure sensing orifice located in a carburetor main bore or an auxiliary bore. In one embodiment, this orifice is moved thereby sensing different combinations of total and static pressure of the moving gas stream in which it is located. In another embodiment, the orifice is fixed with a moveable restrictor which changes the gas flow velocity across the orifice and thus changes the pressure sensed by the orifice. The pressure in this orifice establishes the average reference pressure for a float bowl carburetor or a wet diaphragm carburetor, and hence establishes the fuel flow through the carburetor. This adjustable vent is effective in changing fuel delivery over a wide range of engine operating conditions, and is able to minimize the need for changing high speed jets or mid-range calibrations due to changing atmospheric conditions or other operating parameters. The vent movement can be manual or automatic.

Abstract: A pressure splitter is made having a series or orifices, at least one of which has its effective size change with changes in temperature. This size change is provided by using materials with different thermal expansion rates, these different rates changing the relative positions of a body and the free end of a temperature responsive member. This same principle can be used in conjunction with a pressure responsive element, such as a sealed bellows, to provide a splitter which has an intermediate pressure which changes in response to both temperature and pressure. A splitter with temperature compensation only can be used to effectively modify carburetor fuel flow providing a more constant fuel/air ratio. A splitter using both temperature and pressure responsive elements can be used to more effectively maintain carburetor fuel/air ratio over a wide range of relative air densities caused by changes in atmospheric temperature and altutude.

Abstract: A valve assembly is provided for controlling the flow of fuel to the fuel chamber of a carburetor. The valve assembly includes a housing and a needle. The housing includes a side wall defining an inlet, an outlet in fluid communication with the inlet, and an interior region between the inlet and outlet. The needle is received in the interior region of the housing for movement therein between a closed position blocking the flow of fuel between the inlet and the outlet and an open position allowing the flow of fuel between the inlet and the outlet. The needle includes a post and a skirt fixed to the post. The skirt extends outwardly from the post and cooperates with the side wall to restrict the flow of fuel therebetween dampening the movement of the needle relative to the housing so that the needle moves with the housing when the housing vibrates in response to the operation of the engine.

Abstract: A power capacitor with a plurality of section windings stacked within a housing is provided with an interconnection and fusing arrangement in which insulative spacer elements extending from between adjacent sections support a common electrical bus and an insulative locater element. Fuse wires attached to ends of the section windings extend around an edge of the locater element to the bus and are maintained thereby in spaced relation to avoid interaction between neighboring fuses when one clears.

Abstract: An individual capacitor unit has an individual discharge damping circuit, which may be contained within the unit housing, that is connected between a capacitor stack connection and a terminal of the unit. The damping device includes a predominantly resistive circuit path in parallel with a predominantly inductive circuit path.

Abstract: A power capacitor and method of making it employs the technique of stacking capacitor sections together in an enclosure of which each section includes rolled electrode foils and dielectric layers of which at least one of the electrodes has a rolled edge resulting in a greater thickness in that portion of the section. In order to permit thorough impregnation of the section, the winding tension is deliberately made loose and the initially resulting section is insufficiently tight to retain conductive tabs reliably in contact with the foil electrodes. The stacked sections have, however, between them in the body portion intermediate the rolled edges, one or more sheets of material that compress the body portion and insure reliable pressure contact thereat while not interfering with the impregnation of the fluid throughout the section.

Abstract: Power capacitors with a wide electrode and a narrow electrode and a composite dielectric including a first portion adjacent the narrower electrode that is of higher dielectric constant and/or lower resistivity than the portion adjacent the wider electrode. The first portion may be a porous material whose impregnation with a suitably chosen dielectric fluid results in the desired electrical properties. In such structures the narrower electrode preferably has rounded and smooth edges such as by folding. The wide and narrow electrodes may each comprise one of the externally connected capacitor electrodes. Alternatively, the wider electrode may be electrically floating and arranged between dielectrics and a second narrower electrode in a symmetrical arrangement with the two narrower electrodes serving as the externally connected capacitor electrodes.

Abstract: Wound capacitor sections having interconnections between their electrodes are provided wherein each interconnection comprises a conductive sleeve within a first section in conductive contact with one of its electrodes and a conductive foil tab within another section in conductive contact with one of its electrodes, the tab having an end inserted within the sleeve of the first section.

Abstract: A stack of loosely touching resistive or conductive plates, such as a carbon pile, with a characteristic arc discharge voltage applied to limit voltage, enabling the lowering of protection levels of bypass spark gaps in protection systems for series capacitors and to increase the benefit of the series capacitor by not requiring it to be removed from the line during brief overvoltages.
