Abstract
Abstract A high pressure valve employing a nonrotating needle. The valve actuating stem is threadedly received in a liner sleeve of the valve packing nut. The inner end of the actuating stem is provided with means forming a bore. A valve needle including an enlarged spherical member is adapted to be received in the bore. Essentially line contact is provided between the bearing surfaces of the valve needle and of the actuating stem by the presence of the spherical member between the stem and the valve. Additionally, certain embodiments include means for adjusting the ''''play'''' between the stem and the valve while permitting the valve to be freely rotatable relative to the stem.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
170 words
A high pressure valve including: a body having a valve chamber including means defining a seat, an actuating stem threadedly connected to said body for movement toward and away from said seat; an elongated valve member; said elongated valve member being connected to said stem by connecting means for permitting free rotation of said valve member relative to said stem; said connecting means including at least one spherical surface between said stem and said valve member and a collar member surrounding the mating ends of said stem and said valve member, said valve member extending freely through an axial opening in said collar and having an enlarged head portion rotatably held within said collar; said collar member being threadedly connected to said stem to provide adjustment means for permitting the contact force between said valve member and said stem to be adjusted, and, said enlarged head portion and said collar having generally conically-shaped engagement surfaces to limit tilting of said valve member relative to said head while permitting free rotation.
Claim 2
Dependent Claim
170 words
A high pressure valve including: a body having a valve chamber including means defining a seat, an actuating stem threadedly connected to said body for movement toward and away from said seat; an elongated valve member; said elongated valve member being connected to said stem by connecting means for permitting free rotation of said valve member relative to said stem; said connecting means including at least one spherical surface between said stem and said valve member and a collar member surrounding the mating ends of said stem and said valve member, said valve member extending freely through an axial opening in said collar and having an enlarged head portion rotatably held within said collar; said collar member being threadedly connected to said stem to provide adjustment means for permitting the contact force between said valve member and said stem to be adjusted, and, said enlarged head portion and said collar having generally conically-shaped engagement surfaces to limit tilting of said valve member relative to said head while permitting free rotation.
Claim 3
Dependent Claim
18 words
The valve as defined in claim 1 wherein said spherical surface is formed integrally with said valve member.
Claim 4
Dependent Claim
25 words
The valve as defined in claim 1 wherein said spherical surface is defined by a ball member positioned between said stem and said valve member.
Claim 5
Dependent Claim
19 words
The valve as defined in claim 1 including means for locking said collar member in position on said stem.
Claim 6
Dependent Claim
19 words
The valve as defined in claim 4 wherein said locking means includes a lock nut carried on said stem.
Claim 7
Dependent Claim
60 words
The valve as defined in claim 1 wherein said collar member is bifurcated at its lower end and said enlarged head portion of said valve member is sized such that it can spring said bifurcated end and be moved axially into and out of the lower end of said collar, and wherein means are provided for clamping about said bifurcations.
Claim 8
Dependent Claim
19 words
The valve as defined in claim 1 wherein said stem and said valve member both include mating spherical surfaces.
