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 7):
A valve for controlling fluid flow comprising:\n a) a housing having an elongated cylindrical chamber extending in a first axial direction having a first internal radial dimension; b) said housing having a first inlet passageway means and first outlet passageway means extending in a second axial direction orthogonal to said first axial direction; c) a spool having\n i) 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 first internal radial dimension, said body portion comprising a blocking body portion positionable within said elongated cylindrical chamber to selectively block fluid flow between said first inlet passageway means and said first outlet passageway means; \n ii) first circumferential seal means surrounding a first end of said spool for sealing said first end in said housing; \n iii) second circumferential seal means surrounding a second end of said spool for sealing said second end in said housing; \n iv) a lateral passageway extending through said body portion adjacent said blocking body portion and transverse to said third axial direction; \n d) motive means to move said spool from a first position in said housing in which said blocking body portion blocks fluid flow between said first inlet passageway means and said first outlet passageway means and a second position in said housing in which said lateral passageway is aligned with said first inlet passageway means and said first outlet passageway means; e) alignment means operable between said elongated cylindrical chamber and said spool for maintaining proper rotational alignment of said lateral passageway with said first inlet passageway means and said first outlet passageway means; f) first and second seals mounted on a lateral portion of said spool surrounding a first end of said lateral passageway and a second end of said lateral passageway, lateral surfaces of said first and second seals engaging and sealing said first inlet passageway means and said first outlet passageway means, respectively; g) third and fourth seals mounted on an adjacent lateral portion of said spool surrounding said blocking body portion, each of said third and fourth seals having a lateral surface which engages and blocks fluid flow at said first inlet passageway means and said first outlet passageway means, respectively; and h) a first undercut surrounding an innermost portion of said first inlet passageway means and a second undercut surrounding an innermost portion of said first outlet passageway means to allow ease of transit by said lateral sealing surfaces of said first, second, third and fourth seals.
