A TPMS inflation valve for a commercial vehicle includes an inflation valve body, an inflation valve seat and a sensor subassembly. The inflation valve body and the inflation valve seat are components split apart from each other. The inflation valve is mounted on an automobile rim by means of the inflation valve seat, and the inflation valve body is provided with an installation portion for a valve core. The inflation valve body and the inflation valve seat are assembled and connected to form an airflow channel for communication. A cavity located outside the automobile rim and close to the automobile rim is formed at the position where the inflation valve body and the inflation valve seat are assembled and connected. The sensor subassembly is arranged in the cavity in communication with the airflow channel of the inflation valve or located on the airflow channel.

A valve stem having a hollow tube and a compression sleeve mounted to the hollow tube; wherein the hollow tube and compression sleeve are partially insertable through a container wall opening from an exterior side of the container wall through to an interior side of the container wall, and a mechanism accessible from the exterior side of the container wall to compress the compression sleeve against the interior side of the container wall.

An assembly for a tire pressure management system includes a housing. The housing includes a first branch and a second branch. The second branch is oriented at an oblique angle with respect to the first branch. The first branch and the second branch are in fluid communication with each other and a main branch. The main branch is rotatable with respect to the first branch. A valve assembly is housed within the first branch. The valve assembly provides selective fluid communication between a portion of the tire pressure management system and the main branch. A pressure relief valve assembly is housed within the second branch. The pressure relief valve assembly provides selective fluid communication between the assembly and the atmosphere.

An air maintenance tire system component protector is provided. An air maintenance tire system includes at least one connecting tube extending between and being in fluid communication with an annular air tube and a valve housing. The protector includes a first end disposed proximate the connection of the at least one connecting tube to the annular tube, and a second end disposed proximate the valve housing. A mid-portion of the protector is disposed between the first and second ends. The protector covers an outboard surface of the at least one connecting tube and the valve housing, and includes means for engaging the at least one connecting tube to secure the position of the tube.

A pneumatic valve adapter that couples with a valve stem of a bicycle tire is provided. The valve adapter comprises a cap, a seal, a biasing member, and a sealing member. The cap includes a pin passage and a circumferential concavity on an outer diameter. The receiver is coupled to the cap and is couplable with the valve stem, the receiver having a first opening that is fluidly coupled to a central passage. The seal has a circular shape and cross-section, the seal is disposed between the cap and the end of the receiver, the seal having a second hole that fluidly couples the first opening and the pin passage. The biasing member is disposed in the central passage. The sealing member is disposed within the central passage and biased against the seal by the biasing member, the sealing member being movable between a first position and a second position.

A multi seal extension for an air valve (MSEFAV) that functions in combination with a conventional air valve having an air valve stem in order to extend the length of the stem, thus facilitating the insertion of air via the valve from a greater distance. The MSEFAV includes a rotating securement sleeve, an extension tube, and a stem interface. Inserted into, and attached to, the extension tube is the stem interface, which has multiple seals: a first, end of valve seal; a second, inner thread seal; and a third, core seal. The inclusion and use of the seals provides significantly increased air retention, and projection against moisture and dirt from entering the MSEFAV and air valve, over conventional valve extension designs.

An inflator disposed within a tubeless tire for inflating the tubeless tire. A rechargeable electric storage disposed within a tubeless for providing electricity. An electric air compressor is mounted on an inside surface of the rim of the tubeless tire within the pressure cavity of the tubeless tire. The electric air compressor and an air pressure sensor disposed within the tubeless tire runs by a controller. The electric air compressor has a compressed air inlet vented to atmosphere in a custom valve stem through a conventional hole of a valve stem in the rim of the tubeless tire. A motion activated power generator recharges the rechargeable electric storage. A short-range radio transmits measured pressure data for each tire to a central OBD module plugged into in the vehicle. The central OBD module connects through a smartphone indirectly or directly to a central server via a networked cellular radio tower.

Adapter, tyre parameter monitoring system and method for mounting a tyre parameter monitoring system onto a wheel rim In an embodiment, a tyre parameter monitoring system (2) is provided that comprises an electronic module (4) with a fitting (6) for a snap-in valve, a ball stud (8) coupled to the fitting (6) and a valve stem (10) for a clamp-in valve. The valve stem (10) has a ball socket (12) that is coupled to the ball stud (8) for form a ball joint such that the valve stem (10) is positionable at different angles to the electronic module (4).

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).

A wheel assembly rotational position identifying apparatus includes an acceleration detector, a control section, and a battery. The control section identifies the rotational position of the wheel assembly based on an acceleration detected by the acceleration detector. The control section operates in a control mode that is a selected one of a normal mode and a power saving mode, in which a power consumption associated with identification of the rotational position of the wheel assembly is smaller than that in the normal mode. The control section switches the control mode to the normal mode when an initiation condition is met in accordance with an input from outside. The control section also switches the control mode to the power saving mode when a termination condition is met in the normal mode.
