In some embodiments, the system may include a wheel; and a tube-bursting region of the wheel, wherein the tube-bursting region is configured to facilitate bursting of an associated inner tube when the associated inner tube is pressurized above a predetermined maximum pressure. A tire system also is disclosed. In some embodiments, the system may include a wheel; and a tube-bursting region of the wheel, wherein the tube-bursting region is configured to facilitate bursting of an associated inner tube when the associated inner tube is pressurized above a predetermined maximum pressure. A children's ride-on vehicle also is disclosed. In some embodiments, the vehicle may include a wheel; and a tube-bursting region of the wheel, wherein the tube-bursting region is configured to facilitate bursting of an associated inner tube when the associated inner tube is pressurized above a predetermined maximum pressure.
Abstract:
A pressure relief device (100; 200, 300; 400; 400) for an inflatable tire comprises a body (102; 202; 302; 402; 502) having a chamber (124; 228; 324; 424; 524) with an inflation valve arranged in the body. An overpressure valve in the body releases air when the air pressure in the chamber exceeds a predetermined threshold pressure level. The overpressure valve includes at least one air conduit (128; 228; 328; 428; 528) extending from the chamber through the body in order to provide a passage to a surrounding atmosphere. A ring-shaped resilient member (130; 230; 330; 420; 530) is contractively fitted around an outer surface portion of the body, so as to keep the air conduit in a normally closed state. The properties and dimension of the resilient member are such that it is stretched when the air pressure in the chamber exceeds the predetermined pressure level, so as to provide an air passage from the conduit to the surrounding atmosphere. A plurality of pressure relief devices may be included in a kit, wherein the devices define different predetermined pressure levels.
Abstract:
A simple and frictionless pressure limiting valve assembly for use in pneumatic tire valves wherein a snap diaphragm is movable into and out of a sealing relationship with a valve member by means of the snap action of a snap action diaphragm. The snap action diaphragm may be biased by a means if desired to permit inflation of the pneumatic tire until a desired pressure is reached whereby the snap action diaphragm reverses itself and closes the air flow passageway. This inexpensive assembly only has a few parts. Some preferred embodiments are easy to incorporate (add to) in a conventional tire valve assembly and some others have their specific design. The effective point of activation of the snap action of the snap action diaphragm may be calibrated to precise values.
Abstract:
An improved inflation pressure regulator is disclosed of the type which automatically releases pressure above a predetermined maximum during inflation of a vehicular tire. The regulator, which is particularly suitable for use with low capacity tires and for use with high capacity air pumps, comprises a generally tubular housing adapted to be coupled between a vehicular tire and a source of compressed air. A substantially friction-free flexing seal arrangement within the housing couples the air source to an exhaust aperture and bypasses the tire when the pressure within the tire reaches a predetermined level. The use of a flexing seal substantially reduces seal wear and thus reduces seal leaks and minimizes variations in the regulator rating over the life of the regulator.
Abstract:
An air inlet valve for pressure tanks, pneumatic tires, and the like, the valve comprising a tubular insert with a tire valve core and a mounting body nut, the insert having a snug sliding fit within said body nut and under normal pressure conditions being maintained in sealed relationship by means of spring pressure. When pressure conditions arise in excess of a predetermined value, the excess pressure will result in the retraction of the insert thereby opening the seal between the insert and mounting body nut and relieving excess pressure between the mating interior surface of the body nut and exterior surface of the insert to the outside atmosphere.
Abstract:
A valve assembly for controlling inflation and deflation is provided. The valve assembly includes a rapid-deflate valve cover having a central passage extending through the annular body; an internally threaded portion positioned within the central passage configured to threadingly interface with an externally threaded portion of a valve stem; and a pressure relief formed in the internally threaded portion. The rapid-deflate valve cover can include a valve core positioned within the central passage near the proximal end and configured to selectively permit gas flow from the proximal end into the central passage past the valve core. When the rapid-deflate valve cover is in a closed position, the annular body contacts the valve stem to prohibit gas flow through the central passage. When the rapid-deflate valve cover is in the open position, the body is positioned away from the valve stem to permit gas flow into the central passage.
Abstract:
A system for inflating vehicle tires including: (1) a valve positionable between an opened and a closed position; (2) a pneumatic pathway having a pressure value and in fluid communication with an outlet of the valve and an input of a pressure switch; (3) a vehicle tire in fluid communication with the pneumatic pathway; and (4) the pressure switch configured to actuate the valve to the opened position when the pressure value of the pneumatic pathway drops below a threshold value; and wherein an inlet of the valve is configured to be in fluid communication with an air tank having a pressure value.
