Abstract:
A full-cavity slide valve has undercuts on both the input passageway and output passageway creating ramps to facilitate the O-rings around each of the input and output passageways to slide past without damaging the O-rings. An indicator can optionally be provided to ensure fully open and, if desired, fully closed positions are achieved.

Claim (Index 19):
A valve for controlling fluid flow comprising:\n a housing having an elongated cylindrical chamber extending in a first axial direction having an internal radial dimension, said housing having an inlet passageway and an outlet passageway extending in a second axial direction orthogonal to said first axial direction; a spool comprising:\n a body portion extending in a third axial direction co-extensive with said first axial direction with an external radial dimension substantially equal to said internal radial dimension of said elongated cylindrical chamber, said body portion comprising a blocking body portion positionable within said elongated cylindrical chamber to selectively block fluid flow between said inlet passageway and said outlet passageway; and \n a lateral passageway extending through said body portion adjacent said blocking body portion and transverse to said third axial direction; \n motive means to move said spool from a first position in said housing in which said blocking body portion blocks fluid flow between said inlet passageway and said outlet passageway and a second position in said housing in which said lateral passageway is aligned with said inlet passageway and said outlet passageway; a first seal and a second seal mounted on said spool around said lateral passageway, said first seal and said second seal respectively sealing around said inlet passageway and said outlet passageway when said valve is open; a third seal and a fourth seal mounted on said spool around said blocking body portion, said third seal and said fourth seal respectively sealing around said inlet passageway and said outlet passageway when said valve is closed; and a first undercut surrounding an innermost portion of said inlet passageway and a second undercut surrounding an innermost portion of said outlet passageway to allow ease of transit by said first, second, third and fourth seals.
