Abstract
A fluid-dispensing valve for dispensing pressurized fluid from a chamber employs a spring plate adjacent to the aperture. The spring plate includes a peripheral rim extending about the aperture, a sealing member abutting the aperture, and a plurality of springs extending from the peripheral rim to the sealing member. These springs bias the sealing member to close the aperture when the fluid pressure is less than a predetermined limit and allow the sealing member to open the aperture when the fluid pressure exceeds the limit.
Claims13
A fluid-dispensing valve comprising:
- a chamber containing a fluid;
- an aperture for dispensing pressurized fluid from the chamber;
- and
- a spring plate adjacent to the aperture having:
- (a) a peripheral rim extending about the aperture;
- (b) a sealing member abutting the aperture;
- and
- (c) a plurality of springs extending from the peripheral rim to the sealing member, said springs biasing the sealing member to close the aperture when the fluid pressure is less than a predetermined limit and allowing the sealing member to open the aperture when the fluid pressure exceeds the limit.
A fluid-dispensing valve comprising:
- a chamber containing a fluid;
- an aperture plate having an aperture for dispensing pressurized fluid from the chamber;
- and
- a substantially planar spring plate abutting the aperture plate, said spring plate having:
- (a) a peripheral rim extending about the aperture;
- (b) a sealing member abutting the aperture;
- and
- (c) a plurality of flat curved springs suspending the sealing member from the peripheral rim, said springs biasing the sealing member against the aperture to close the aperture when the fluid pressure is less than a predetermined limit, and deforming to move the sealing member away from the aperture to thereby open the aperture when the fluid pressure exceeds the limit.
