A valve assembly is provided that can perform an overpressure relief function to vent fluid from a first component, such as to vent fuel vapor from a fuel tank, to a second component, such as a carbon canister, without being affected by the vapor pressure in the vent line to the second component. That is, the valve opens to provide pressure relief when needed regardless of the vapor pressure against which it opens. The valve assembly may also include a solenoid that is controllable to allow fluid flow separately from the movement in response to vapor pressure.

Valve arrangement for venting a coolant circuit of an internal combustion engine

Номер: US20120097364A1
Автор: Christoph Anton, Matthias Honzen, Sebastian Riedl
Принадлежит: Audi AG

A valve arrangement for venting a coolant circuit of an internal combustion engine having several subcircuits includes a valve which is in fluid communication with a primary vent line extending from one of the subcircuits. At least one secondary vent line is in fluid communication with the valve and extends from another one of the subcircuits. The primary and secondary vent lines are connectable to a shared third vent line which feeds into a compensating reservoir arranged at a geodetically highest point in the coolant circuit. The valve is constructed to establish a continuous fluid communication of the primary vent line with the compensating reservoir via the third vent line and to establish a fluid communication of the secondary vent line with the compensating reservoir via the third vent line only in the presence of air bubbles in the secondary vent line.

Принадлежит: Donghee Industrial Co Ltd

A noiseproof vent valve for a fuel tank is provided. A damping member installed in the vent valve has at least two elastic pieces, preferably the four elastic pieces. The movement of the float is absorbed by elastic deformation of the elastic pieces, and thus the float is prevented from coming into contact with a lower end forming the bottom of a valve body. However excessively the float fluctuates, no “clicking” contact noise occurs at the vent valve. As a result, the merchantability of a hybrid vehicle sensitive to low noise can be greatly increased.

Passive vacuum relief valve for ultra-low temperature freezers

Номер: US20140034157A1
Автор: Yongrak Kwon
Принадлежит: Global Cooling Inc

A passive vacuum relief valve for an ultra-low temperature freezer. A thermally conductive tube extends through a freezer cabinet wall and opens into the interior cabinet space. The tube also extends outwardly from the cabinet wall in thermal exposure to ambient air so that it can receive heat from the ambient air. A valve enclosure has a chamber opening into the tube and is also positioned in the ambient air. A check valve, preferably a ball type, is formed in the valve enclosure and is polarized in a direction permitting ambient air to flow through the chamber and the tube into the freezer cabinet. The exposed tube is passively heated by the ambient air and provides a thermal conduction path to the valve and to the portion of the tube extending through the freezer cabinet wall to prevent moisture from freezing and locking the valve and/or obstructing the tube.

In a method for operating a fuel system of an internal combustion engine, the fuel system has a fuel tank and a ventilation device, which has at least one vent valve, for ventilating the fuel tank. The magnitude of deformation caused by an internal pressure of the fuel tank of a deformation zone of the fuel tank is ascertained and the vent valve is opened when the magnitude of deformation exceeds a limit value. 110-. (canceled)11. A method of operating a fuel system of an internal combustion engine , comprising:fluidly connecting a ventilation device of the fuel system via a vent line with a fuel tank of the fuel system for ventilation of the fuel tank;providing an actuator for actuating a first vent valve of the ventilation device;connecting in parallel to the first vent valve two overflow valves configured to enable opposite throughflow directions and to open or close a throughflow in dependence on a pressure differential between a first section of the vent line on one side of the first vent line and a second section on an opposite side of the first vent valve;ascertaining a magnitude of deformation of a deformation of a deformation zone of the fuel tank as caused by an internal pressure of the fuel tank; andopening a second vent valve of the ventilation device when the magnitude of deformation exceeds a limit value.12. The method of claim 11 , further comprising mechanically transmitting the deformation of the deformation zone to the second vent valve so that the deformation causes a force to open the second vent valve.13.
