An anti-spray structure for a connection of an air nozzle of a tire of a vehicle and a connection hose of an air compressor, and the air compressor contains: a box, a sealant supply can, and a connection hose. The box accommodates the air compressor. The sealant supply can includes an open segment and a supply tube. The connection hose includes a first segment and a second segment. The second segment has an anti-spray connector including a fitting sleeve. The fitting sleeve has a threaded orifice, a through orifice, and a projected shoulder. A cylindrical base includes a cylindrical room, a stepped coupling segment, a conduit, and a first stepped portion. A first spring is received into the cylindrical room. A valve bolt includes a post, a connecting disc, spaced slots, and a first seal ring. A lock element includes a hollow cavity, a hexagonal tab, and a tilted extension.

A check joint structure for a connection of an air nozzle of a tire and a connection hose of an air compressor, the air compressor contains: a box, a sealant supply can, and a connection hose. The box includes a body of the air compressor. The sealant supply can includes an open segment and a supply tube. The connection hose includes a first segment and a second segment. The second segment has a check connector which includes a fitting sleeve, and the fitting sleeve has a threaded orifice, a through orifice, and a projected shoulder. A cylindrical base includes a cylindrical room, a stepped coupling segment, a conduit, and a first stepped portion. A first spring is received into the cylindrical room to abut against the first stepped portion. A valve bolt includes a contacting element, at least one cutout, a head, a conical rib, and a neck.

An inflation adapter is used for connecting with an inflator unit and assembled to a tire valve, and the inflation adapter has a nozzle body and a sleeve sleeved on the nozzle body. The nozzle body has a ventilation channel, a sealing washer, and at least one locking part. The ventilation channel is formed axially through the nozzle body. The sealing washer is mounted in the bottom end of the ventilation channel. The at least one locking part is radially movable on the nozzle body. A user pushes the sleeve to abut against the at least one locking part to assemble the inflation adapter with the tire valve. The quickly assembling/dissembling inflation adapter saves the operation time and improves the operation convenience for driving safety.

A chuck for inflating a tire having a Presta valve includes a valve engagement device defining an aperture with a central axis and a diameter, the valve engagement device movable radially with respect to the central axis to increase and decrease the diameter of the aperture. A locking device can engage with the valve engagement device to lock the valve engagement device in a selected radial position with respect to the central axis of the aperture. The chuck can include a seal positioned within the valve engagement device, the entire seal moving radially with the valve engagement device.

A tire inflation viewing device that enables to view the proper operation of the inflation arrangements and that, in turn, enables to determine which of all of the tires is being inflated and has an air leak.

A coupling manifold assembly has both regulated and unregulated flow orientations and includes a manifold body and a pressure regulator couplably received into the manifold body. The manifold body includes a pair of connection ports between which flow is movable through the manifold body, with the pressure regulator being received into a flow path between the connection ports. The pressure regulator is configured to regulate flow in a first direction between the connection ports and to allow for unregulated flow in an opposite second direction between the connection ports.

A nozzle adapter for an inflation valve contains a connection seat, at least one control element, at least one returning element, a seal cover, and a controlling means. The connection seat includes an imaginary axis line, an inlet, an outlet, an air stop ring, a conduit, an engagement position, a coupling, and a stopping means. A respective control element has a fixing shaft, an engaging portion, and a controlled portion. The at least one returning element is arranged on the at least one control element. The seal cover is fixed outside the coupling, and an airtight space is defined in the coupling. The controlling means mounted on a center of the connection seat opposite to the inlet and in the conduit of the airtight space to move with the controlled portion.

Methods and systems are provided for using a forced induction system of an engine on-board a vehicle as a source of compressed air to pressurize depressurized objects on-board and external to the vehicle. In one example, a method may include, in response to a pressure of the depressurized object being below a threshold pressure while the engine is off, fluidly coupling a discharge of a forced induction system to the depressurized object, wherein the engine includes the forced induction system, and pressurizing the depressurized object by supplying electrical power to the forced induction system.
