A double-use nozzle adapter includes a main body, a switch unit, and a needle unit. The switch unit includes a shifting member and a rigid retaining member. The rigid retaining member is arranged between the shifting member and the main body. The shifting member shifts the rigid retaining member between a first position and a second position. The needle unit is slidably installed in the main body and includes a needle. In the first position, the shifting member drives the rigid retaining member to press against the needle, thereby preventing the needle from moving with respect to the main body and making the needle connectable to a Schrader valve. In the second position, the rigid retaining member moves between the shifting member and the main body, so as to allow the needle to move with respect to the main body and make the needle connectable to a Presta valve.

A pump head configured to secure various air valve types is disclosed. The pump head may include a housing and an interior unit sized and shaped to receive a valve head. A moveable pin disposed within the housing coaxially with the first axis may define a pin notch disposed about an exterior circumference of the moveable pin. A first taper unit may be disposed in the housing coaxially with the first axis and coupled to the pin return spring. A second taper unit may be disposed in the housing coaxially with the first axis and adjacent to the first taper unit. An elastic taper C-ring may be disposed between the first and second taper units. The second taper unit is moveable towards the first taper unit, thereby compressing the elastic taper C-ring circumferentially in at least one of two positions, the elastic taper C-ring compressed about the pin notch in the first position and about the valve head in the second position.

Systems and methods for fleet inspection and maintenance using a robot are provided. The robot may detect a maintenance issue of a vehicle of a fleet of vehicles via one or more sensors, generate a navigation route to a position proximal to the maintenance issue of the vehicle, traverse along the navigation route to the position, and execute a maintenance to rectify the maintenance issue of the vehicle. The robot may include a mobile base removably coupled to a modular platform for performing a maintenance task.

A sensing sealant liquid container for repairing an inflatable article, preferably a tyre, comprises a first portion produced by injection moulding and a second portion produced by injection moulding, the first and the second portion being connected to each other to delimit a volume inside which a sealant liquid is retained, an outlet tube for the sealant liquid when the container is pressurized and a sensor for verifying the functional connection of the tube to the inflatable article, and at least one track electrically connected to the sensor and co-moulded on one of the first and the second portion, the track defining a contact releasable electrical connection.

A control system for an air maintenance tire system is provided. The control system includes a sensor unit that in turn includes a pressure sensor for measuring a pressure in the tire cavity and an antenna for transmitting pressure data. A processor receives the pressure data and includes a memory for storing a predetermined low-pressure threshold. Actuation means that are in communication with the processor and actuate and de-actuate operation of the air maintenance tire system. A first signal is transmitted from the processor to the actuation means to actuate operation of the air maintenance tire system when the measured pressure in the tire cavity is below the threshold. A second signal is transmitted from the processor to the actuation means to de-actuate operation of the air maintenance tire system when the measured pressure in the tire cavity is at or above the threshold.

A puncture repair fluid container includes: a container body including a storage portion for storing a puncture repair fluid and an opening portion provided at one end of the storage portion; and a cap mounted to the opening portion. The cap includes: an introduction path for introducing compressed air from outside; a discharge path for discharging the puncture repair fluid to the outside; a switching valve for switching two paths disposed between the introduction path and the discharge path; and a switching knob for operating the switching valve. The switching knob includes a disk-like switching knob body provided with a tab portion protruding in a thickness direction of the switching knob body, and a maximum height position at which a height of the tab portion is maximum is positioned outward of a center position of the switching knob body in a radial direction of the switching knob body.

An inflator with an air guiding sleeve includes a chassis, a core and a drive motor installed in the chassis, an air guiding sleeve and a cooling fan. The air guiding sleeve has an air guiding hole penetrating through the air guiding sleeve. The drive motor includes a main body and a shaft rotatably installed to the main body, and the shaft has an end protruded from the main body and provided for driving the core to move and the other end protruded from the main body and provided for connecting the cooling fan. The air guiding sleeve includes a positioning shell and an air guiding ring connected to the positioning shell, and the positioning shell is installed to the chassis and/or the drive motor, and the air guiding ring is sheathed onto the external side of the cooling fan and installed around the cooling fan.
