181	IMPROVED PILOT-ASSISTED PRESSURE RELIEF VALVE	PCT/US1988002839	1988-08-19	WO1989009359A1	1989-10-05	WEBSTER ELECTRIC COMPANY, INC.; ELLIOTT, Daniel, J.
An improved compact pilot-assisted pressure relief valve is disclosed, including a vent piston (80) or the like hydraulically dividing the valve body bore (40) into a hydraulic fluid chamber and a spring chamber (45) which is vented to atmosphere, such that backpressure is eliminated entirely for both faster reaction to pressure impulses and improved accuracy in pre-load setting of the valve assembly.
182	VALVE FOR BATTERY	EP22382642.1	2022-07-05	EP4195391A1	2023-06-14	WASS, ANTON; SOUCY, PAUL
Valve for battery that, applicable to expel the air in case of overpressure generated in a battery because of its cells heating and being constituted from an external body (2) and a plunger (3) that travels inside it pushed by the battery pressure. The valve presents two opening positions, depending on the level of pressure generated, by means of coupling to the said plunger (3), at least: -a first O-ring (5) that closes the passage of the air when there is no pressure and opens it when the plunger (3) moves at a first position from a given degree of pressure, - a second O-ring (6) that prevents the direct exit outside of the air when there is only a first degree of pressure and allows it when the said degree of pressure is exceeded that opens the plunger (3) at second position, and -a ventilation element (4) that allows the passage of the air through it, but not the passage of the water.

Embodiments of this application relate to the technical field of power batteries, and disclose a two-way vent valve, a battery, and an electrical device. The two-way vent valve includes: a valve seat, where the valve seat is configured to form a gas duct, and the gas duct includes a first end and a second end; a two-way valve assembly, where the two-way valve assembly is movably disposed in the gas duct, and is configured to open or close the gas duct through movement relative to the gas duct; and a first elastic component, configured to exert a force on the two-way valve assembly to close the air duct, and, when an air pressure difference between the first end and the second end of the gas duct is greater than a first threshold, the two-way valve assembly is configured to overcome the force of the first elastic component to open the gas duct. In this way, the two-way vent valve according to the embodiments of this application implements two-way controllable exchange of gas between the two ends of the valve. When being used in a battery or a device that uses the battery, the two-way vent valve can reduce the impact caused by moisture outside the battery and reduce risks of condensation.

193	SELECTIVELY OPENED BI-DIRECTIONAL CRACKING VALVE	EP95903604.7	1994-11-25	EP0746712B1	2001-10-10	POLI, Robert, G.
A bi-directional cracking valve that can be selectively opened. Bi-directional cracking valve (10, 70) is formed using an elastomeric membrane (34). Centered within the elastomeric membrane is a slit (36) that remains closed, blocking fluid flow through the device until a differential pressure across the elastomeric membrane exceeds a predefined cracking pressure, sufficient to force fluid through the slit. The elastomeric membrane is an integral part of an elastomeric cylinder (28), which is mounted in a valve carrier (12). The valve carrier includes ports disposed at opposite ends and the ports are adapted to couple to tubing. An operator can selectively enable fluid flow through the device by squeezing side tabs (40, 42) disposed on opposite sides of the elastomeric membrane together, forcing the slit open. A latch (46) is provided to keep the bi-directional cracking valve in an open state.
