A one-way valve (10) comprises: a valve housing (100) having a first end portion, a second end portion, a valve housing channel (110), and a stopper projection (108) provided within the valve housing channel (110); a valve body (200) having a first end portion, a second end portion, and a valve body channel (202) in fluid communication with the valve housing channel (110), the second end portion of the valve body (200) being snap-fit to the first end portion of the valve housing (100); and a sealing plug (300) slidably disposed within the valve body channel (202), wherein an inner diameter of the valve housing channel (110) is greater than an inner diameter of the valve body channel (202) and an outer diameter of the sealing plug (300), and a distance between the stopper projection (108) and the second end portion of the valve body (200) is greater than a longitudinal length of the sealing plug (300). A tire repair glue bottle (1) having a one-way valve comprises: a bottle body (20) containing glue; an air intake device (40) attached to the bottle body (20); a bottle lid (50) attached to the bottle body (20); a glue tube (30) provided within the bottle body (20) and having one end connected to the bottle lid (50); and an one-way valve (10), wherein the second end portion of the valve housing (100) of the one-way valve (10) is connected to the other end of the glue tube (30).

A gas migration prevention module can include a housing, control line connections configured to connect the housing between control line sections, spaced apart pistons sealingly received in the housing, and a fluid volume defined between the pistons. A control line system can include an upper control line section, a lower control line section in fluid communication with a downhole tool, and a gas migration prevention module connected between the upper and lower control line sections, the lower control line section providing fluid communication between the gas migration prevention module and the downhole tool, and the gas migration prevention module comprising spaced apart pistons and a fluid volume defined between the pistons, the fluid volume being in fluid communication with an exterior of the gas migration prevention module.

A wireless communication safety break device is disclosed which has an upper safety break portion having a fuel inlet, an upper portion check valve, an upper portion communications device, an upper portion contact point or switch, and a lower safety break portion having a fuel outlet, a lower portion check valve, a lower portion contact point or switch, and a locator device.

Embodiments of apparatus for controlling the movement of matter, including but not limited to one-way fluid valves, are disclosed. The apparatus may include a transition nozzle, a funnel nozzle, and a reverse flow blocker arranged in series in a case. A counter-flow area may be disposed about the funnel nozzle. The apparatus may permit matter to flow in a first direction, and discourage or prevent flow in a direction reverse to the first direction. Control over the flow of matter may also enable the matter to be harvested, sorted, separated or combined with injected matter.

A self-acting pressure activated drain valve includes at least one inlet configured to receive a fluid. A drainage passage delivers the fluid to at least one outlet where the fluid is expelled. The self-acting pressure activated drain valve further includes a flexible diaphragm configured to operate in an open position and a closed position based on a pressure. The flexible diaphragm is normally biased in the open position such that fluid is delivered from the at least one inlet to the at least one outlet via the drainage passage. The pressure, however, initiates the closed position such that air is prevented from flowing through the drainage passage.

A gas turbine engine includes a fan, a compressor, a combustor, a turbine, a bypass duct, and a bearing compartment assembly. The bearing compartment assembly includes a fluid pump, a compartment, a fluid line between the fluid pump and the compartment, and a damper check valve located in the fluid line. The damper check valve is a unitary, monolithic component that is configured to restrict a reverse flow from the compartment to the fluid pump substantially more than the damper check valve restricts a standard flow from the fluid pump to the compartment.

The present disclosure relates to a pneumatically driven fluid pump apparatus having an outer pump housing for collecting liquid to be pumped, and a valve assembly in communication with liquid admitted through an inlet end of the outer pump housing and collecting within the outer pump housing. The valve assembly includes a housing assembly and a poppet valve assembly disposed within the housing assembly to act as a one-way check valve when pumping collected liquid out from the outer pump housing. The poppet valve assembly includes a poppet valve component including a relief area that helps to depressurize an interior area of the valve assembly, to facilitate rapid movement of the poppet valve element from an open position toward a closed position, when only a pressurized fluid flow being used to eject the collected liquid is flowing past the poppet valve component.
