Definitions

  • the invention is related to the fields of valves, and more particularly, to fuses and one-way valves.
  • Fluid handling devices are increasingly in demand, and there is an increased need for fluid handling devices that increase the safety and reliability of a system. Fluid handling systems are necessary for applications such as home care, point of care testing, fuel cells, beverage dispensing, etc. In order for a fluid handling device to be effective and efficient, it should be simple, reliable, and inexpensive. In many applications, it is desirable to decrease the number of components used in a fluid system to reduce costs and complexity. Therefore it is desirable to combine the functionality of multiple fluid handling devices into new fluid handling devices.
  • a fuse valve can act to shut off the flow of fluid when the fluid flow or pressure becomes too high.
  • Typical fuse valves remain open to the flow of fluid in any direction until the fluid flow or pressure reaches a maximum in one flow direction, at which point the fuse valve closes the flow of fluid.
  • U.S. 3,872,884 describes a fuse valve featuring a poppet biased open with a spring. The poppet is pushed closed when the poppet experiences a pressure differential strong enough to counteract the force of the spring.

What is needed, therefore, is an improved valve that can act as both a fuse valve and a oneway valve. Such a valve will allow fluid to flow in a positive direction below a maximum pressure while simultaneously preventing fluid to flow in a negative direction.
