  • Patent number: 7634984
    Abstract: An air induction system for an engine to remove contaminants from intake air prior to delivery to the engine. The system includes an assembly for filtering air which is mounted in advance of the engine, and a duct for delivering air from the assembly to the engine. A sealing system is provided which prevents entry of unfiltered air while simultaneously permitting movement of the engine relative to adjacent parts of the airframe as engine power setting varies. The seal is protected from high pressures in the duct which can occur in operation of the engine.

  • Patent number: 7575014
    Abstract: An air induction system for an engine having an improved mechanism for control of an intake door. The system includes a housing having an opening for receiving intake air. A power activated door is pivotable between a closed position wherein the opening is closed and an open position wherein intake air may enter through the opening. Linkages operatively connect an actuator cylinder to the door. The linkages are configured such that movement of the cylinder produces a corresponding rotation of the door which is non-uniform across the cylinder's range of motion. The linkages include first and second bellcranks mounted for pivotal motion, and a link which interconnects the bellcranks. Movement of the cylinder at a first position causes pivoting of the door, while movement at a second position causes substantially no pivoting of the door.

  • Patent number: 7491253
    Abstract: An air induction system for an engine to remove contaminants from intake air prior to delivery to the engine. The system includes a filtering unit having barrier filter panels attachable to a mounting frame. The filter panels are interchangeably usable. A juncture between first and second filter panels and the mounting frame is located at a region of relatively lower quantity of intake air flow. The juncture includes lugs on the filter panels which facilitate interchangeability. An opening above the filtering unit permits easy installation and removal of filter panels.

  • Publication number: 20070022723
    Abstract: An air induction system for an engine to receive intake air and provide for improved performance. The system includes a housing having two separable sections interengageable at a seam. A seal located along the seam provides a generally airtight engagement. An adjustable connection is for securing the seal at a selectable position to promote effective sealing. The seal is shaped for stability, having an inner end which is relatively wider and an outer end which is relatively narrower.

  • Patent number: 6153098
    Abstract: The present invention comprises a fluid filter element which has a hollow perforate cylindrical supporting core. A relatively fine filter media of substantial cross section is spirally wound about the supporting core with adjacent layers spaced from each other and with the fine filter media accommodating fluid flow for filtering in both a radial and circumferential direction through the cross section and with free access through the cross section to the supporting core. In substantially the same manner, a relatively coarse filter media of substantial cross section is disposed in the space between the layers of fine filter media and with the coarse filter media exiting at the supporting core, the coarse filter media accommodating fluid flow for filtering in both a radial and circumferential direction through the cross section and with free access through the cross section to the supporting core.

  • Patent number: 5651887
    Abstract: A filtration system having an in-line filter cartridge with the inlet at one end of the filter cartridge and the outlet at the opposite end of the cartridge. The filter cartridge is connected to the cartridge mounting on the fluid conduits via quick-disconnect couplers with built-in automatic water shutoff capability which enables the filter cartridge to be installed and removed in a horizontal movement. A recirculating bypass is provided in the system which includes a pair of bypass branch lines to recirculate the fluid and prevent trapped stagnant water in the bypass lines. In a shown preferred usage, the filtration system utilizes a filtration cartridge and mount to allow filter cartridges to be easily mounted upon and removed from automatic beverage dispensers.

  • Patent number: 5611925
    Abstract: Disclosed is a hub ring for a filter wherein a supporting member having a plurality of supporting portions is interposed between a pair of keep plates, a supporting plate for a filter wherein a plurality of wave portions extending substantially in the circumferential direction are arranged in the radial direction, and methods for manufacturing these members. The hub ring has a great opening ratio to achieve a low pressure loss property and causes substantially no residence of polymer, and the hub ring can be manufactured at a low cost. The supporting plate has high pressure resistance, low-pressure loss property, good directivity of polymer flow and excellent polymer mixing effect, and it is suitable for use as a retainer disposed inside of a filter.

  • Patent number: 5536396
    Abstract: A kit for preparing batches of filtered water includes a container, a reservoir/funnel and a filter cartridge. The reservoir funnel is dimensioned to conform to a predetermined surface of the container to fit thereon during storage of the kit and the reservoir funnel further includes a tapered outlet designed to cooperate with the filler opening on the top of the container so as to be rigidly supported by the container. The funnel/reservoir includes a well into which a cartridge carrying a filter media can be inserted. The configuration is such that water poured into the funnel/reservoir must pass through the filter cartridge before entering the container.
