An inflation pump connector includes a housing a sliding groove extending along a longitudinal axis and a pressing device slidably received in the sliding groove. The pressing device includes an airtight ring and a clamping member. The clamping member includes a base and a first claw. The first claw includes a first clamping arm, a first pressing portion, a second clamping arm, and a first hollow portion. The first clamping arm is connected to the base. The first pressing portion is connected to an end of the first clamping arm opposite to the base. The second clamping aim is connected to the first pressing portion. The first hollow portion is disposed between the first clamping arm and the second clamping arm. The first pressing portion is movable towards the longitudinal axis and to squeeze and deform the airtight ring.

An integrated tire inflation valve comprises an inlet configured to receive air from an air tank, a pressure protection assembly configured to control air flow into the tire inflation system when an air pressure reaches a pre-set pressure level, a valve assembly in fluid communication with the pressure protection assembly, a pressure regulator configured to be adjusted to a desired pressure to thereby allow air through the pressure regulator at a desired level, a flow switch configured to selectively allow air therethrough, and an outlet configured to provide air from the flow switch to one or more tires of a vehicle. The inlet, pressure protection assembly, valve assembly, pressure regulator, flow switch, and outlet are all positioned within a single housing.

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.

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 inflation valve for inflating containers with non-rigid walls comprising a tubular body defining a passage with a first opening at one end and a second opening at its opposite end, adapted to be secured to a container, a sealing disc adapted to sealingly close off the second opening to the passage in the tubular body, and adapted to open the second opening mechanically when an inflation device is inserted into the passage through the first opening and thus gas may be passed into the container through the second opening, thereby moving the sealing disc away from the second opening, a guide member located within the passage of the tubular body; a spring adapted to assist the sealing disc to close off the second opening; and a gasket and/or sealing ring adapted to assist the sealing disc to close off the second opening.

The present invention relates to inflatable bodies or systems with bounding walls or bladder structures and at least one valve assembly thermally bonded thereto. More particularly, the present invention provides a valve assembly for inflatable bodies typically made from a thermoplastic rubber material or the like, which will exhibit significantly increased strength and durability during inflation and while inflated, especially at and around the interface between the air valve assembly and the bounding wall of the inflatable body because of the enhanced strength of the interface through thermal sealing.

A device provides a pneumatic pressure medium via a pressure medium source for at least one pressure medium chamber in particular of a vehicle seat of a motor vehicle. The device has a pressure medium source for the pressure medium and a pressure medium line disposed between the pressure medium source and at least one valve. At least one connection for a pressure medium line is disposed between the valve and the pressure medium chamber. A control module actuates the pressure medium source and the at least one valve. The device further has a housing. A motor of the pressure medium source is located between the control module and a pump of the pressure medium source.

A tubeless air valve stem has a body, an airtight element, and a sleeve. The body has a passage, a through hole, and at least one side hole. The passage is formed on a top end of the body. The through hole is formed through a bottom end of the body and is in communication with the passage. The at least one side hole is formed through an outer surface of the body and is in communication with the passage. The airtight element is disposed around the body. The sleeve is disposed around the body for closing the at least one side hole. Gas or liquid can be injected into a tubeless tire via the at least one side hole. The intake efficiency of the tubeless air valve stem can be maintained and is not influenced by the remaining reinforcing agent.

A nozzle for fast inflation and deflation includes a flexible plastic body, an air tube, and a sealing plug. The flexible plastic body is connected to a bottom of the air tube, and the sealing plug is flexibly connected to an outer port of the air tube. A valve sheet is in the flexible plastic body. For air inflation or deflation, a gap as an air channel is formed between the valve sheet and the air tube for inflation or deflation without pressing the flexible plastic body. To store air, the air tube is bent downward until the flexible plastic body is deformed to cause the valve sheet to contact the inner port of the air tube so as to avoid air leakage. Then, the air tube is allowed to be slowly plugged by the sealing plug. The problem of internal air leaking out is thus fully solved.

High-altitude balloons and apparatuses for filling such high-altitude balloons are provided. As an example, an apparatus for filling a high-altitude balloon includes a tube extending through envelope material of the balloon is provided. The apparatus also includes a flange connected to a first end of the tube. The flange is connected to an interior surface of the balloon. A fitting is connected to a second end of the tube. The fitting is configured for attachment with an apparatus for filling the balloon with lift gas. In addition, methods of filling high-altitude balloons with lift gas and methods of manufacturing balloons are also provided.
