Abstract: A solenoid valve system, wherein the valve member is provided with a seal member disposed thereabout. The solenoid valve is especially suitable for use with exhaust gas recirculation systems. The seal member is operable to slide axially relative to the valve member, including the stem portion thereof. An optional lubricant is provided between the valve member and the seal member so as to provide a relatively low friction environment therebetween when the valve member is in motion. An optional biasable member, in operable association with the seal member, is provided so as to maintain proper positioning of the seal member, e.g., during operation of the solenoid valve system.

Abstract: A lead frame disposed within the confines of an engine cover, having an insulating portion and an electrically conducting portion. The conducting portion has at least one electrically conducting interconnect. Both the insulating portion and the electrically conducting portion form an integral piece for retaining and accurately positioning devices within an internal combustion engine. The lead frame includes a plurality of retaining elements for retaining or positioning of at least some of the devices; and an electrical connector member extending outside the confines of the internal combustion engine, the electrical connector member having a plurality of electrically conducting terminals in electrical communication with at least some of the devices within the internal combustion engine by means of the at least one electrically conducting interconnect, whereby at least some of the devices are retained and accurately positioned within the internal combustion engine.

Abstract: A method for filling and degassing a pouch contained in a cartridge. A fluid injection unit introduces fluid into a rotatable pouch. The pouch contained in the cartridge is permitted to rotate from a vertical position for degassing and weighing to a horizontal position for fluid introduction. After several rotational cycles, accurate pouch weighing and complete evacuation of the pouch results in a precise fluid loaded pouch.

Abstract: An apparatus precisely delivers a prescribed amount of fluid into a degassed pouch contained in a cartridge. The apparatus has a rotating cartridge holding member that alternately positions the cartridge in either a horizontal position for filling or a vertical position for degassing. A digital weighing element associated with the fixture enables the cartridge to be weighed during the filling process to ensure the delivery of a predetermined amount of fluid.

Abstract: An exhaust gas recirculation system includes a valve body having an exhaust port adapted for fluid communication with a source of exhaust gas, an intake port adapted for fluid communication with the intake manifold of an internal combustion engine, and a valve member. The system further includes a drive member mounted to the valve body and including a mechanical output which is rotatable in opposed first and second directions. A gear train is operatively disposed between and in engagement with the rotatable mechanical output of the drive member and the valve member. More specifically, the mechanical output rotating in either of the first or second directions imparts linear, reciprocal motion directly to the valve member through the gear train thereby moving the valve member between opened and closed positions to control the flow of exhaust gas from the exhaust port to the intake port.

Abstract: An exhaust gas recirculation system for an internal combustion engine including a valve body having an exhaust port adapted for fluid communication with a source of exhaust gas, an intake port adapted for fluid communication with the intake manifold of an internal combustion engine, and a valve member movably supported within the body between open and closed positions thereby controlling the flow of exhaust gas from the exhaust port to the intake port. A diaphragm housing is operatively mounted to the valve body and supported thereby. The diaphragm housing defines a vacuum cavity in fluid communication with a source of negative pressure and an atmosphere cavity in fluid communication with a source of second pressure. A diaphragm member is disposed between the vacuum and atmosphere cavities and is operatively connected to the valve member.

Abstract: A closed-loop controlled system solenoid actuated EGR valve includes an engine mount for attachment to a vehicle engine, a valve housing to which the engine mount is attached, a motor housing positioned above the valve housing, and a sensor housing. The valve housing includes a valve inlet adapted to receive engine exhaust gas and a valve outlet which communicates the engine exhaust gas from the valve inlet to an engine intake system. The motor housing has a bobbin, an armature, and a valve stem disposed in a bore formed therein. The valve stem is in communication with a plunger extending from the sensor housing to monitor the position of the valve stem with respect to the valve seat. A guide bearing is positioned in the housing to guide the armature while a valve stem bearing is positioned in the valve housing to contact and position the valve stem with respect to the valve seat while a valve opening is being closed.

Abstract: The present invention relates to a bulk tobacco racking device that is designed to assist in loading and closing a sectional bulk tobacco rack of the type including a generaly U-shaped tine section, an elongated bar section, and a pair of latches that extend from said tine section which are adapted to engage and latch with said elongated bar section. The racking device of the present invention comprises a frame structure having a bottom and a pair of laterally spaced side frame assemblies disposed on opposite sides thereof for receiving respective sections of the rack during the loading and racking operation. At least one of said side frame assemblies is laterally adjustable to assure that the respective rack sections are properly fitted and disposed between the side frame assemblies.

Abstract: Apparatus for transferring harvested material from a harvester into a trailer moving alongside the harvester at a slightly faster rate, for which purpose a conveyor inclined at an oblique angle to the direction of motion of the vehicles is loaded with harvested material and a shuttling means reciprocates the conveyor and its drive means in the conveying direction while a drive interrupting means causes the conveyor to be driven only during one sense of the reciprocating drive of the shuttling means.

Abstract: A method of handling material which has been harvested comprising the steps of placing the material on a conveyor arranged at an oblique angle to a direction of motion of a trailer and a harvester moving at differential speeds and simultaneously reciprocating the conveyor along its length and driving the conveyor to advance the harvested material therealong from the harvester to the trailer.

Abstract: A carburetor has an induction passage, a fuel circuit and a choke valve positioned at the inlet of the induction passage. A metering rod extends transversely of the induction passage and has a variable diameter end portion projecting into an outlet of the fuel circuit. The metering rod is movable relative to the outlet in response to the choke valve opening and closing to control the quantity of fuel entering the induction passage. An opening force is exerted on the choke valve in response to the vacuum created in the engine, the exertion of this opening force being delayed until after an initial opening force has been exerted on the choke valve. The exertion of the second opening force moves the choke valve from a first position to a second and more fully open position.

Abstract: A staged carburetor has a body in which a pair of induction passages are formed, an inner passage having a venturi and an outer passage encircling the inner passage. A throttle valve positioned at the outlet of the pair of passages controls the flow of air through the passages. Fuel is delivered to the inner passage through a fuel circuit having an outlet at the venturi. A fuel metering rod extends transversely of the passages and has a variable diameter end portion projecting into the outlet. The metering rod is movable relative to the outlet to vary the quantity of fuel delivered. An air valve positioned in the outer passage normally closes the passage whereby air is initially drawn into the engine only through the inner passage. Increased demand for air by the engine results in opening of the air valve so air is drawn into the engine through both passages.
