Limited action flow control fluid dispenser

A fluid dispensing system comprising:

• a fluid container;
• a fluid supply line coupled to the fluid container;
• and
• a fluid dispenser, coupled to the fluid supply line,
• the fluid dispenser including a housing having a fluid inlet, a fluid outlet, and a cavity, the fluid inlet coupled to the fluid supply line and opening into the cavity, the cavity opening coaxially into the fluid outlet,
• wherein the fluid dispenser includes a plunger longitudinally positioned in the cavity, the plunger being slidable between a first position and a second position, the first position permitting fluid to flow from the fluid inlet through the cavity and out the fluid outlet, and the second position preventing fluid flow,
• the plunger having a first end and a second end, a substantially uniformly concave section, a velocity reducing section, a sealing section, and a constant volume section positioned between the first and second ends;
• the substantially uniformly concave section being located adjacent the fluid inlet,
• the velocity reducing section being located at the first end of the plunger proximate to the fluid outlet,
• the sealing section being located between the substantially uniformly concave section and the velocity reducing section, and
• the constant volume section being located between the sealing section and the velocity reducing section;
• and
• a nozzle attached to the fluid outlet.

A fluid dispenser comprising:

• a housing having a fluid inlet, a fluid outlet, and a cavity, the fluid inlet opening into the cavity and the cavity opening coaxially into the fluid outlet;
• a plunger formed from a rigid material and longitudinally positioned in the cavity, the plunger being slidable between a first position and a second position, the first position permitting fluid to flow from the fluid inlet through the cavity and out the fluid outlet, and the second position preventing fluid flow,
• wherein the plunger has a first end and a second end, a substantially uniformly concave section, and a constant volume section positioned between the first and second ends,
• the substantially uniformly concave section being located adjacent the fluid inlet, and
• the constant volume section being located downstream from the concave section and the fluid outlet;
• a sealing section for sealing the cavity, located between the substantially uniformly concave section and the constant volume section;
• and
• a nozzle attached to the fluid outlet.
