Valves for inflating tires of tired wheels, in particular tires for vehicles, wherein the term “vehicles” refers to motor vehicles, vans, trucks, motorcycles or in general elements of locomotion on tires. More in detail, a metal valve (1) of the clamp-in type for inflating tires (2) associable with a TPMS transducer (3) by a locking screw (4) and arranged to be mounted, by a fixing system including a nut (5) adapted to screw onto a thread (18) provided on the stem (8) of the valve (1), on a rim (6) of a wheel, wherein the fixing system includes an element (7) that irreversibly yields when a preset tightening torque is reached for the locking nut (5), and wherein the element (7) that irreversibly yields is associated with the stem (8) of the valve (1).

Provided is a valve, relating to the mechanical equipment technical field, comprising a valve body provided with a passage configured for allowing a fluid to pass through and a valve core disk provided within the passage and rotatable relative to the valve body. The valve core disk is provided with through holes and has one side face provided with a one-way diaphragm which is used for sealing the through holes in one direction to enable the valve core disk to seal the passage in one direction. Since the valve core disk can rotate relative to the valve body, one-way-inflation and -deflation can be realized, and during deflation, the passage can be opened for deflation just by rotating the valve core disk. Users can adjust a deflating speed by rotating the valve core disk. The valve not only has a simple structure, but also is convenient for the user to deflate.

Provided is a replacement necessity determination device for a snap-in valve having an inner end to which an air pressure detection device including an air pressure sensor and an acceleration sensor is coupled. A control device of the replacement necessity determination device is configured to predict an angle change amount of the snap-in valve and the air pressure detection device with respect to a wheel caused by a centrifugal force based on a rotational speed of the wheel and an acceleration detected by the acceleration sensor, calculate a degradation indication value of an elastic body of the snap-in valve based on a maximum value of the angle change amount during a period set in advance, and determine necessity of replacement of the snap-in valve based on an integrated value of the degradation indication value.

An adjustable multiple bladder system for an article of footwear is disclosed. The bladder system includes an outer bladder that may be inflated using an external pump. A valve member is disposed within the outer bladder and divides the outer bladder into two distinct inflation chambers. The inflation chambers may be inflated separately.

An air bag packaging arrangement and a self-adhesive checking valve, the air bag packaging arrangement includes an air bag and an air valve which is the self-adhesive checking valve. The air bag includes first and second cell overlapped layers to form an air chamber and a valve opening. The air valve includes first and second sealing films overlapped between the first and second cell layers, and a strengthening film provided between the first valve film and the first cell film to strengthen a joint strength between the first valve film and the first cell film, so as to prevent the first valve film from being broken, so as to further avoid an air leakage.

A pressure and temperature compensated valve assembly includes a flow valve allowing inflation flow from a control port to a tire port and controlling deflation flow from the tire port to the control port. A throttle valve restricts deflation flow between the tire port and the control port when deflating the tire at high flow rates or when tire pressure is high, thus enabling the flow valve to be closed. The throttle valve includes a throttle diaphragm that throttles in response to flow from the tire port and which does not restrict inflation flow from the control port. The valve assembly further includes a temperature responsive member engaging the flow valve, and which deforms in response to a change in temperature in the valve assembly, thus negating temperature effects on the flow valve, allowing the flow valve to close at a consistent force across a range of operating temperatures.

An air valve connecting device or attachment includes a mouth engaged in a housing and having a compartment for engaging with either a US or French inflation valve, a barrel engaged into the housing and engaged onto the mouth, an actuator slidably engaged in the housing and engageable with the barrel, and a cam member is engageable with the actuator for selectively forcing the actuator and the barrel to compress the mouth to grasp either of the inflation valves to the housing, a tube is slidably engaged in the actuator and extendible into the mouth, and a catch is slidably engaged in the actuator and engageable into the actuator for selectively engaging with and for retaining the tube to the actuator.

Described herein is an inflation/deflation device of the type comprising a portion provided with an intake orifice for taking in a gaseous fluid under pressure, and a portion provided firstly with an inflation/deflation orifice designed to communicate with the confinement capacity, and secondly with a discharge orifice opening out between the two portions; and a valve member control system for inflation/deflation operations per se. In accordance with the invention, one of the portions is provided with arrangements for receiving a washer, which arrangements are suitable for allowing said washer to deform elastically, under the effect of a pressure of a gaseous fluid discharging through the discharge orifice, so as to release face-on bearing by an annular protuberance provided on the other portion, and so as to generate a fluid discharge passage between said annular protuberance and said washer.
