Abstract
A valve comprising: a valve body; and a valve stem disposed at least partially within the valve body, the valve stem comprising a sidewall defining a central lumen and at least one opening in the sidewall, wherein the valve is adapted to prevent fluid flow through the lumen when the at least one opening is disposed within the valve body and permit fluid flow through the lumen when the at least one opening is exposed from the valve body, and wherein the valve is essentially free of a spring.
Claims19
An assembly comprising:
- a fluid reservoir;
- a valve adapted to restrict fluid flow relative to the fluid reservoir, the valve comprising:
- a valve body;
- and
- a valve stem disposed at least partially within the valve body, the valve stem comprising a sidewall defining a central lumen and at least one opening in the sidewall,
- wherein the valve is adapted to prevent fluid flow through the lumen when the at least one opening is disposed within the valve body and permit fluid flow through the lumen when the at least one opening is exposed from the valve body, and wherein the valve is free of a spring, and a retention feature adapted to be installed within an aperture of the valve body, wherein the retention feature is detachable from the valve stem, wherein the valve stem defines at least one of the locking flange or a portion of the valve stem extending from the sidewall, and wherein at least one of the locking flange or the portion of the valve stem is adapted to engage with the retention feature to selectively maintain the valve stem in an open and closed configuration.

A method of operating a valve comprising:
- providing a valve comprising:
- a valve body;
- and
- a valve stem disposed at least partially within the valve body, the valve stem comprising a sidewall defining a central lumen and at least one opening in the sidewall,
- wherein the valve is adapted to prevent fluid flow through the lumen when the at least one opening is disposed within the valve body and permit fluid flow through the lumen when the at least one opening is exposed from the valve body, and wherein the valve is free of a spring, and a retention feature adapted to be installed within an aperture of the valve body, wherein the retention feature is detachable from the valve stem, wherein the valve stem defines at least one of the locking flange or a portion of the valve stem extending from the sidewall, and wherein at least one of the locking flange or the portion of the valve stem is adapted to engage with the retention feature to selectively maintain the valve stem in an open and closed configuration;
- removing the retention feature disposed between a first stop feature and the locking flange of a valve stem;
- translating the valve stem in a longitudinal direction;
- and
- installing the retention feature between the second locking feature of the valve stem and the locking flange.
