Abstract
A valve comprises: a housing defining a chamber; a fluid outlet defined by a fluid outlet wall; and a first fluid outlet orifice and a second fluid outlet orifice comprising a rigid seat. The valve comprises a movable gate, that is flexible and/or compressible and impermeable. The moveable gate is more flexible than the rigid seat, has a planar surface, and is configured to slidably move in a first axis. The movable gate is configured to be positioned so that it is located between a fluid inlet orifice and the second fluid outlet orifice when the valve is in a closed position, wherein fluid pressure within the chamber causes the movable gate to seal the second fluid outlet orifice via the rigid seat, and not the fluid inlet orifice. The valve may employ gate shapes that generate and/or exploit Bernoulli effect forces when fluid passes though the valve.
