Abstract: A subassembly for a valve device for controlling air flow in an intake manifold. The subassembly includes a cartridge including a plurality of compartments having partially open opposing sidewalls, wherein adjacent partially open side walls of adjacent compartments are spaced apart a distance to define a groove therebetween, a plurality of partitions each having a through-hole therein and being disposed in the grooves defined between adjacent partially open side walls of the adjacent compartments. The partitions complete the formation of the opposing side walls of the adjacent compartments and each compartment is alignable with an air intake runner of an intake manifold.

Abstract: Disclosed herein is an actuator for regulating the flow of fluids in first and second flow paths of an internal combustion engine. The actuator includes a motor having a rotatable drive shaft, a gear assembly driven by the drive shaft of the motor, and first and second output shafts rotated in opposite directions by the gear assembly. The first and second output shafts are operatively linked to valves in the first and second flow paths, respectively, to regulate the flow of fluids in the first and second flow paths.

Abstract: A method of modifying an air intake manifold to control air intake runners. The method includes the steps of providing a cartridge including a plurality of compartments, each spaced apart to define a groove therebetween, snap-fitting a bushing carrier having a rotatable bushing into each of the grooves, positioning a flap having a slot over each of the compartments, inserting a shaft through each slot and each bushing thereby rotatably retaining each of the flaps within one of the plurality of compartments, positioning the cartridge over the air intake manifold so that each of the plurality of compartments is substantially axially aligned with one of the air intake runners, and removably connecting the cartridge with the air intake manifold.

Abstract: Disclosed herein is an intake manifold assembly that comprises a first outer covering, a second outer covering connected to the first outer covering that together define a chamber having an intake port, and a flow channel insert. The second outer covering has an outlet port positioned within its interior surface and the flow channel insert is nestingly connected to the outlet port with the rest of the flow channel insert received within the chamber. The flow channel insert being a single piece that defines a channel having a first end and a second end.

Abstract: An extruded multilayer seal member having an expanded temperature range and an improved compression set resistance wherein the seal member comprises a first fluoroelastomer as the inner layer of the multilayer seal member and a second elastomer as the outer layer of the multilayer seal member; and a method for manufacturing the multilayer seal member which comprises extruding a multilayer tubular structure, crosslinking the extruded multilayer tubular structure on a mandrel, cutting the multilayer tubular structure to provide a plurality of uniform seal members and recovering the seal members, are described.

Abstract: Apparatus includes a motor-vehicle, internal-combustion-engine air intake manifold having an intake-manifold first shell attachable or monolithically joined to an intake-manifold second shell to surround an internal manifold volume. The first shell has a wall with at least a portion having undulating concave and convex regions as defined exterior to the internal manifold volume of the attached or monolithically-joined first shell and second shell.

Abstract: An assembly for controlling an air intake runner of an air intake manifold. The assembly includes a cartridge including a plurality of compartments. Each of the compartments has a plurality of that are joined to define a central opening and an outer perimeter. Adjacent compartments are spaced apart to define a groove between each of the compartments. The assembly also includes bushing carriers that are configured to be snap-fit into one of the grooves of the cartridge. The assembly further includes bushings configured to rotatably fit within the central openings of the bushing carriers. Each of the bushings has an outer rim and an open center. Flaps including a slot and having a shape configured to substantially adjustably seal the central opening are also included and a shaft is included that extends through the slots of the flaps and the open centers of the bushings.
