摘要:
Tires are typically inflated through an air conduit mounted on the tire carcass and extending through a hole in the metal rim on which the tire is mounted. Now and then relative slipping between the tire and rim has caused the air conduit to be sheared off, deflating the tire. The present invention overcomes this problem by moving the air conduit (26, 33, 37) completely away from the rim. The air conduit (26, 33, 37) extends from the air chamber (12) through the track wall (10) to the side wall (8) of the carcass (7) and terminates in an air valve receptacle (27) accessible at the side wall (8) of the carcass (7).

An inflation valve for inflating containers with non-rigid walls, has a body with a passage and first tubular part with a first opening at one end leading into the passage and a second opening at its opposite end leading into the passage. A cap is removably fitted over the body for closing the first opening to the passage. A first sealing disc, which closes off the second opening to the passage, is adapted to open the second opening when an inflation device is inserted into the second opening to allow gas to be inserted into the container through the second opening. A guide member is located within the first tubular part to support a spring for assisting the first sealing disc in closing off the second opening.

A magnetic dust cap for a pneumatic tire comprising an external valve stem having a threaded top portion having a width, a length, a top end and a bottom end and a rubberized bottom portion having a width and a top end. The magnetic dust cap comprises a body for capping the external valve stem and magnetic means disposed within the body to removeably adhere to a washer. The washer is adapted for threaded engagement over the threaded top portion of the valve stem.

A cargo or dunnage air bag inflation and deflation system comprises an inflation-deflation valve member (112), a cap-type plug member (114), and an air gun implement (128) having a fill nozzle (186) and an exhaust nozzle (188) mounted upon opposite ends thereof for respective connection to the valve member (112) in order to perform inflation and deflation operations. The valve member (112) comprises a flapper or check valve element (172) pivotally mounted upon the valve member (112) so as to permit inflation or deflation of the cargo or dunnage air bag when the flapper or check valve element is moved away from its valve seat, and to substantially maintain the cargo or dunnage air bag in its inflated state when the flappper or check valve element is effectively seated upon its valve seat. The cap-type plug member (114) is removably mounted upon the inflation-deflation valve member (112) so as to effectively close and seal the valve assembly when the cap-type plug member (114) is mounted upon the valve member (112), and effectively uncovers the valve member (112) when the cap-type plug member (114) is dismounted from the valve member (112) so as to permit the air gun implement (128) to be operatively connected to the air valve member (112) in order to perform an inflation or deflation operation. The air gun implement (128) includes a nosepiece (206) which unseats the valve element (172) to allow deflation.

A self sealing valve includes a diaphragm (602) positioned within a valve housing (606) by a movable hanger arm (610) which suspends the diaphragm from a mounting point (612) in the center of an air inlet (614). The hanger arm (610) is a rotating diaphragm hanger that has one end secured adjacent to an inner wall (618) of the air inlet (614) by a pair of pins (634). There is a contoured section (648) between the hinge pins (634) of the inner wall which interfaces with a contoured end (650) to provide for at least four distinct interaction possibilities. A first retains the hanger arm (610) in a valve closed position. A second causes the valve to exhibit a biased closed condition. A third locks the valve open and a fourth facilitates assembly.
