Rinsing assembly with swivel actuating valve

摘要

A rinsing assembly has a swivel actuation valve disposed between a riser pipe member and second pipe member. The swivel actuation valve has an inner body member disposed co-axially within an outer body member. The outer body member is axially movable relative to the inner body member. A sealable internal fluid path is defined through the inner body member and the outer body member. The fluid path is sealed when the body members are in a first relative axial position and is open when the body members are in a second relative axial position. Internal biasing means bias the inner and outer body members towards the first relative axial position.
