An inflation system for tubeless bicycle tires may include a valve, a sealant canister, a pump head, and/or a valve core adapter. The valve, sealant canister, and pump head may collectively facilitate sealant injection into a tire by a user. The valve has an external valve seat, and includes a valve body, a valve stem extending through the length of the valve body, and a retaining mechanism for the valve stem disposed interior to the valve body. The valve stem is configured to move relative to the valve body, such that a resilient seating surface disposed at a proximal end of the valve stem is displaced relative to a valve seat formed by an exterior surface of a proximal end of the valve body.

A bicycle wheel comprises a rim and a valve assembly. The rim includes a radially inner wall having an inner opening and a radially outer wall having an outer opening. A first portion of the rim includes a first securing feature (e.g., inner threads). The valve assembly is positioned in the inner opening and outer opening and includes a second securing feature (e.g., outer threads) engaging the first securing feature. The rim can include a plate that defines the first engaging feature. The valve assembly preferably includes a valve stem and a resilient bumper coupled to the valve stem and aligned with a second portion of the rim. The valve assembly can further include a seal member compressed between the valve stem and the rim. Preferably, the seal member is positioned in an annular groove in an underside of an enlarged head of the valve stem.

A valve with elastic deformation and having a tubular core adapted to form an internal air passage from an external longitudinal end of the valve to an internal longitudinal end, the tubular core being at least partially surrounded by a sleeve of elastically deformable material and having a bulb shape widening in proximity to the internal longitudinal end of the valve and ending in an internal longitudinal bulb end. A cup made of rigid material includes a first portion facing an internal longitudinal bulb end face and at least one second portion curved away from the internal longitudinal end of the valve, the cup serving as a way of limiting deformation of the bulb.

An inflatable survival vest includes an inflatable bladder having an inflation inlet through which a gas is input to inflate the bladder. The bladder is configured in the shape of a vest. The bladder has a plurality of parallel seams that divide the bladder into tubular channels. The tubular channels cause the vest to have a wavy outwardly facing surface with crests and troughs and a wavy inwardly facing surface with crests and troughs. An inner air chamber is positioned along the inwardly facing surface of the bladder. A shell with limited stretch-ability overlies the inflatable bladder, thereby limiting outward expansion of the bladder such that the bladder is adapted to expand inwardly pressing the inner air chamber against a body of a person wearing the bladder.

A control circuit for controlling the pressure of a wheel enclosing a first volume and a second volume includes a controlled pressure line, a first line, connectable to the controlled pressure line and connected to the first volume for introducing air inside the first volume, and a second line, connectable to the controlled pressure line and connected to the second volume for introducing air inside the second volume. The control circuit further includes a first spool valve, which is a three way-two positions valve, having a first position in which the controlled pressure line is connected to the first line, and a second position, in which the controlled pressure line is connected to the second line. The first spool valve switches from the first position to the second position if the pressure in the first volume exceeds a predetermined pressure.

Air valve for a pneumatic tire has a threaded shaft between a first end defining an air inlet and an opposite, second end that is located within the bounded space of a tire mounted on a rim. The air passageway through the air valve has at least one outlet at the distal end of the valve that exists the device through a side portion rather than the terminal end of the device. In a preferred embodiment the air passageway is T-shaped so that air flowing into the tire flows in a non-linear path, exiting the air outlets transverse to the air flow through the inlet into the air passageway.

A valve connector comprises a body including an inlet port, an outlet port defining a longitudinal axis, at least one aperture extending between an exterior surface of the body and the outlet port. The valve connector also comprises a sleeve arranged about the exterior surface of the body and movable relative to the body between a clamping position and a release position and a biasing member applying a biasing force against the sleeve towards the clamping position. The valve connector further comprises a clamping mechanism including at least one clamping member arranged at least partially within the aperture. When the valve is received in the outlet port, the clamping member is inwardly displaceable into the outlet port in response to the biasing force biasing the sleeve toward the clamping position, such that the clamping member engages the valve.

A valve assembly is provided and includes a valve housing, an actuator housing coupled to the valve housing and configured when actuated to open a normally-closed valve element in the valve housing whereby pressurized fluid is permitted to flow through the valve housing and a solenoid valve. The solenoid valve includes an armature-valve element balanced to remain in a closed position and an electromagnet. The electromagnet generates magnetic flux that moves the armature-valve element into an open position such that at least a portion of the pressurized fluid flows into the actuator housing to actuate the actuator housing.

An electro-pneumatic valve assembly includes a valve having a valve housing and a poppet and a solenoid valve having an actuator housing and a valve body. The valve housing has a wall that defines a valve inlet that is arranged to receive a fluid flow from a pressurized container and defines a valve outlet and a first port. The poppet is disposed within the valve housing and is movable between a first position and a second position. The actuator housing defines an opening. The valve body has a first wall that defines an inlet that is fluidly connected to the first port and a second wall that defines an outlet that is fluidly connected to the second port.
