Abstract
A priming system including a resilient chamber having flexible walls and a first check valve in a first fluid pathway between the resilient chamber and a fluid reservoir such that a fluid flows through the first check valve only in a direction from the fluid reservoir toward the resilient chamber and the fluid returns to the fluid reservoir through a second fluid pathway between the resilient chamber and the fluid reservoir upon compression of the walls of the resilient chamber.
Claims20
A priming device comprising:
- a housing comprising:
- an inlet passage;
- an outlet passage;
- a planar surface forming a seat, wherein the inlet passage and the outlet passage extend through the seat;
- a resilient chamber coupled to the seat and having flexible walls, wherein the inlet passage and the outlet passage are fluidly coupled to the resilient chamber;
- and
- a check valve disposed in the inlet passage such that a fluid flow through the check valve is only in a direction toward the resilient chamber,
- wherein compression of the flexible walls of the resilient chamber directs a fluid out of the resilient chamber and through the outlet passage.
