Abstract:
A system is provided. The system includes a wheel assembly which defines a chamber that houses a pressurized fluid. A wheel valve assembly is attached to the wheel assembly and is in fluid communication with the chamber. The wheel valve assembly is operable between an open position and a closed position. The wheel valve assembly includes an area having a first flow capacity. A valve assembly is selectively in fluid communication with the wheel valve assembly. The valve assembly includes an area formed in a perforation that has a second flow capacity. The second flow capacity is less than the first flow capacity.
Abstract:
Disclosed is an inflation valve that enables a user to quickly inflate and deflate an inflatable object. The inflation valve can include an inflation chamber that is an adequate size to capture a breath of air blown by a user from a distance away from an outside opening of the inflation chamber. This allows surrounding air into the area of low pressure created by the moving air, thereby greatly increasing the amount of air entering the inflatable object. To prevent air from escaping the inflatable object, the inflation valve can include a non-invertible one-way valve and/or an invertible one-way valve. Each valve can prevent air from escaping the inflation chamber until adequate pressure is applied from the outside opening of the inflation chamber, for example, as a result of a user blowing air into the inflation chamber. The invertible one-way valve can be inverted to reverse the properties of the valve.
Abstract:
This invention relates to a threaded valved inflation needle designed for controlled inflation or deflation of balls and toys by communicating with standard air sources, inflation methods and pressure monitoring devices. The invention is useful for adjustment and monitoring of internal pressure in balls that utilize a rubber valve of the type that commonly appears in recreational balls. The invention is also useful for controlled inflation of toys that utilize plastic pull out valves for communicating with external air sources. The utility and convenience of the threaded valved inflation needle is further enhanced by a cover designed to hold, protect, and lubricate the threaded valved inflation needle when not in use.
Abstract:
The subject of the present invention is a valve (100) for extracting, by pumping, a fluid (F) contained in a space (E), said valve (100) comprising: a) a main body (10) having a first opening (01) for the passage of said fluid (F) during pumping, and b) an indicator means (20) configured to indicate whether or not the fluid (F) is passing through the first opening (01).
Abstract:
Valve (1) having a cap arrangement (5) for tyres and tubes intended for mounting on a wheel rim, especially for motor cars where the valve has a freely accessible tubular valve body (2). The cap arrangement (1) is furnished with a first part of a securing means (9, 6; 13; 14; 6) and the tubular portion of the valve (2,3) is furnished with a second part (2; 15; 16) of the securing means, where the securing means are mutually cooperating for securing the cap arrangement on the outer free end of the tubular part of the valve. The mutually cooperating securing means are designed as a snap-lock connection, where the first part of the snap-lock connection is constructed in the cap arrangement while the other part is constructed directly on the valve. Further, there is an embodiment with an operating handle (18) for the cap arrangement and an embodiment where the cap is connected to the valve.
Abstract:
A check valve for an inflatable device comprising a poppet urged by a conical spring to annularly seal uniformly around its entire periphery to assure more uniform cracking pressure about its entire periphery. In one embodiment the check valve comprises a locking key to lock the valve closed irrespective of the cracking pressure that may otherwise may have cracked the valve open. In another embodiment, the check valve comprises a manual dump feature that allows rapid dumping of air from the inflatable irrespective of low cracking pressure that may exist in the inflatable.
Abstract:
An apparatus for regulating airflow into a rim mounted vehicle tyre is disclosed. The apparatus has an elongated valve housing (1) with an inlet end (IA), an outlet end (2) and a central portion between the outlet end (2) and inlet end (1A). The outlet end includes a rim insertion portion (3) configured to fit into an aperture in the tyre rim. A piston (8) is disposed within the housing (1). The piston includes a valve member (19). A coil spring (22) acts between the housing (1) and piston (8). In use, the piston (8) is biased to an open position for passage of air into the tyre and is movable against the spring bias under air pressure build up in the tyre to a closed position. At the closed position, the valve member (19) seals against a valve seat (21). The piston (8) and spring (22) are located in the central portion of the housing (1) clear of the rim insertion portion (3). The rim insertion portion (3) is of a reduced size not obstructive to the mounting of the tyre.
Abstract:
A personal flotation device (PFD) (10) comprising an inflatable bladder (16) which is attached to the wearer by means of a waist belt (12) and anchor straps (13) joined to a second belt (15) attached directly to the bladder (16). Both a gas cartridge device (28) and an oral device (18) are provided for inflating the bladder (16). The gas nozzle (34) through which the gas enters the bladder (16) from the gas cartridge (28) includes a plurality of gas paths (43, 49) which permit gas flow substantially perpendicular to the gas inlet nozzle axis (45) thus overcoming difficulties in inflating the PFD caused by the extremely cold gas vented from the cartridge (28) freezing the bladder material of the PFD in the vicinity of the gas inlet nozzle (34). A similar gas inlet nozzle (34) can also be used for the oral inflation device (18).
