An inflation manifold connected to dual pneumatic tires by air hoses provides a central location for tire inflation and location of pressure sensors. A hose block connected to dual pneumatic tires by air hoses provides a central location for location of pressure sensors. The pressure sensors may be TPMS sensors or a combination of TPMS sensor and pressure gauge.

A tyre inflating device (100) comprises an air feed line (200) and an inflating module (300), which includes: a primary valve (301) movable between a closed position and an open position for closing and opening the feed line (200); a first cylinder (302a) connected to the primary valve (301) and supplied with air by a first branch (201a) of the feed line (200); a second cylinder (302b) connected to the primary valve (301); a shutoff valve (303) located on the first branch (201A); a control leg (202) from which there extends a relief duct (201a′), which is configured to gradually release air from the first cylinder (302a) to the outside environment and includes at least one between (i) a plurality of throttles (304) located in series and (ii) a shutter placed in a constriction element (305) located in the relief duct (201a′).

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.

A valve-coupler system has a lever that extends under a length axis of the valve body to enable one-handed operation. The valve-coupler body has an opening that is configured over a valve stem and a seal actuator having a lever that can be rotated about a pivot with a single hand to create a seal around the valve stem. Additionally, a valve-coupler may have a gas inlet valve that can be activated by the same single hand to open the valve and allow gas to flow into the valve stem. The inlet valve may be configured in line with the lever whereby the inlet valve is opened when the lever is rotated about the pivot to contact the inlet valve. The inlet valve may be configured on the valve body for manipulation by a user's finger or thumb. The inlet valve may be on the top of the valve body.

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. A lock arm may be configured to engage the first taper unit with the second taper unit, thereby compressing the elastic taper C-ring circumferentially in one of at least 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.

An air compressor contains: a box in which the air compressor and a sealant supply device are accommodated. The air compressor is configured to produce high-pressure airs, and the sealant supply device has an air inlet pipe and a supply pipe. An air outlet pipe of the air compressor is connected with the air inlet pipe, and the air compressor is detachable from the sealant supply device. The air inlet pipe is configured to receive the high-pressure airs from the air compressor, the supply pipe is configured to output chemical sealant from the sealant supply device, and a tube is configured to communicate the air inlet pipe with the supply pipe. A rotation element includes a driven portion and a central stem. The rotation element is fitted on the second sub-tube. The central stem of the rotation element abuts against a top of the tube.

The invention is directed to a device for inflating a tire that includes a housing with at least one first connection port and at least one second connection port. The second connection port includes connecting means to interconnect the device with a pressure tank. The first connection port is fluidically connected to the second connection port by means of a fluid passage. Furthermore the device comprises a first valve. When a pressure tank is connected to the second connection port and when the first valve is in a closed state, the first valve is suited to prevent air from flowing from inside of the pressure tank out of the first connection port. When the first valve is in an open state, it is suited to allow passage of air from inside of the pressure tank through the fluid passage to the first connection port. The device further includes a second valve that is connectable to an inflator for pressurizing the tank.

A rotary union for a tire inflation system includes an axle housing and a wheel axle rotatably mounted in the axle housing. The wheel axle has a flange for attachment of a wheel rim. The wheel axle is received by a passage socket that is connected for conjoint rotation to the wheel axle and supported by a radial bearing relative to a bearing seat within the axle housing. A compressed air duct is disposed inside a cylindrical wall of the passage socket such that the compressed air duct is connected at one end to a pressure connector mounted on the axle housing and at the other end to a tire connector mounted on the passage socket. The passage socket is sealed rotationally movably with respect to an adjacent inner side of the axle housing such that an enclosed chamber is formed between the pressure connector and the compressed air duct.
