Abstract
A fluid valve assembly for a seat comprising a fluid bladder, the fluid valve assembly comprising: a valve housing at least partially defining a first fluid inlet, a first fluid outlet, and a first exhaust outlet; a diaphragm disposed at least partially in the valve housing and configured to flex between a first position and a second position according to a first fluid pressure difference between the first fluid inlet and the first fluid outlet.

A fluid valve assembly for a seat comprising a fluid bladder, the fluid valve assembly comprising:
- a valve housing at least partially defining a first fluid inlet, a first fluid outlet, and a first exhaust outlet;
- a diaphragm disposed at least partially in the valve housing and configured to flex between a first position and a second position according to a first fluid pressure difference between the first fluid inlet and the first fluid outlet;
- wherein, in the first position, the diaphragm restricts fluid flow from the first fluid inlet to the first exhaust outlet and the first fluid outlet;
- and
- in the second position, the diaphragm permits flow from the first fluid inlet to the first fluid outlet and restricts fluid flow from the first fluid outlet to the first exhaust outlet.
A fluid valve assembly for a seat comprising a fluid bladder, the fluid valve assembly comprising:
- a valve housing at least partially defining a fluid chamber, a fluid inlet, and a fluid outlet;
- a diaphragm disposed in the valve housing and configured to flex between a first position and a second position according to a fluid pressure difference between the fluid inlet and the fluid outlet;
- and
- a plate disposed in the valve housing and separating the fluid chamber into a first section and a second section, the plate defining a first fluid passage and a second fluid passage;
- wherein, in the first position, the diaphragm restricts fluid flow through the first fluid passage;
- in the second position, the diaphragm permits flow from the fluid inlet through the first fluid passage to the fluid outlet;
- and
- the second fluid passage is configured to permit a first flow rate in a first direction toward the fluid outlet and to permit a second flow rate in a second direction toward the fluid inlet that is less than the first flow rate.
