A male external incontinence device comprising a drainage tube assembly having a proximal chamber in fluid communication with a drainage tube, the proximal chamber comprising an atmospheric equilibrium valve assembly. The atmospheric equilibrium valve assembly has an airway conduit with a upper portion in fluid communication with the proximal chamber, and a lower portion having an air inlet chamber. A one-way air valve disposed in the airway conduit above the air inlet chamber, the one-way air valve comprising a first pair of opposing walls disposed at a first set of opposing angles such that the first pair of opposing walls abut each other at an apex, the apex having a self-sealing slit.

A pressure cap for a cooling system of a vehicle may include a reservoir fill port which is mounted at an upper portion of a reservoir in which cooling water is stored in a cooling system of the vehicle; an external cap for closing an upper end portion of the reservoir fill port; a pressure valve disposed in the reservoir fill port to allow the inside and the outside of the reservoir fill portion to fluidically-communicate with each other; a valve seal provided to allow the air to flow from the outside into the internal to the cooling system by being deformed when pressure in the internal to the cooling system is lower than a predetermined pressure; and a positive pressure spring elastically supporting the pressure valve such that the pressure valve closes the internal to the reservoir fill port.

An exhaust gas turbocharger with a wastegate port configured to permit some exhaust gas flow to exit a turbine volute upstream of the turbine wheel and enter a bypass channel thereby bypassing the turbine wheel, a valve with a valve head dimensioned to seat on a valve seat and to move between a seated position and an open position, the bypass channel having a sidewall contoured to surround the valve head as the valve head moves between the seated position and the open position, he bypass channel sidewall shaped so that a throat area (A.sub.t) area between the bypass channel sidewall and valve head gradually increases as the valve head moves between the seated and the open position, such the bypass flow is controlled by the throat area (A.sub.t) and not the area between the valve head and the valve seat.

A fully-integrated flow-control valve assembly for top-filled fuel tanks incorporates both a float valve assembly and a shut-off valve assembly in a single unit that screws into a threaded aperture in the top of the fuel tank. Whereas all other systems having similar function rely on an inlet valve and a level control/vent positioned apart from one another and intercoupled with a bleed line that runs either inside or outside the fuel tank, the device of the present invention directly mounts the two devices together and allows a simple installation. There is no need for a line that couples two remotely positioned units of the prior art flow-control assemblies.

A liquid tank system comprises a main liquid tank, an outlet communicating between a fluid circuit and the main liquid tank, an inlet communicating between the fluid circuit and the main liquid tank, and an auxiliary cavity. First vent passage and second vent passage(s) communicate between the main liquid tank and the auxiliary cavity and allows liquid and gas to flow from the main liquid tank to the auxiliary cavity. The second vent passage has a flow control device regulating flow through the second vent passage and having a set point at which it allows liquid and gas to flow from the main liquid tank to the auxiliary cavity only when a pressure in the main liquid tank is beyond a threshold. The liquid tank system has an attitude envelope in which the liquid tank system is configured such that, in use, the flow control device blocks flow through the second vent passage when an end of the first vent passage in the main liquid tank is above a liquid level, and the flow control device allows gas and/or fluid flow through the second vent passage when main fluid tank pressure is above the threshold and the end of the first vent passage in the main liquid tank is below the liquid level.

A venting apparatus is provided for regulating discharge of fuel vapor from a fuel tank and admission of outside air into the fuel tank.

A pressure cap structure for a cooling system having variable opening pressure, which is applied to a cooling system for circulating cooling water to radiate heat generated by an engine of a vehicle, and maintains the inside pressure of the cooling system in a predetermined range, the pressure cap may include a positive pressure spring mounted in a valve body, and operated to connect the cooling system to the outside when the pressure of the cooling system rises, and a shape memory member restored to the initial shape when reaching a predetermined temperature, and mounted between the positive pressure spring and a spring guard supporting the positive pressure spring.

An anti-siphon system for use with an irrigation system, such as lawn sprinkling system is disclosed. The system includes a backflow prevention valve with a bonnet- and poppet valve system with a conical spring that biases a lower poppet valve head, and engages the valve body. The use of the conical spring simplifies the mechanism, while providing reliable backflow prevention.

A lockable valve-actuated suction apparatus includes a resilient anchor member having an inner side arranged to seal against a reference surface, and an outer side. The anchor member includes a vent port extending between its inner and outer sides. A movable member is slidably movable between a sealing position wherein the vent port is blocked and a venting position wherein the vent port is unblocked. A twist-to-lock coupling connection is provided between the movable member and the anchor member. The twist-to-lock coupling connection is operable by rotating the movable member between a locking state and an unlocking state. The locking state of the twist-to-lock coupling connection is characterized by the movable member being locked against the slidable movement relative to the anchor member. The unlocking state of the twist-to-lock coupling connection is characterized by the movable member being unlocked against the slidable movement relative to the anchor member.
