摘要： A lubrication/bleeder fitting (10) is provided including a cap (14), a body (12) having a first end (15) coupled to the cap, a second end (17) opposite the first end, and an axially extending cavity (40) extending between the first and second ends. The fitting also includes a poppet seat (50) in the axially extending cavity and a poppet (60) disposed in the axially extending cavity and having a nose portion to seat against the poppet seat. A resilient member (64) is disposed in the axially extending cavity between the poppet and the second end, and a spacer (66) is disposed in the axially extending cavity and seating an end of the resilient member opposite the poppet. The poppet is biased in a first position against the poppet seat by the resilient member to prevent fluid flow through the axially extending cavity.
