Abstract
Abstract Manifolds assembly having a plastic body with intersect flow passages and valve members for controlling communication between the passageways. Stops limit the movement of the valve members between predetermined positions, and the valve members can be removed from the body and reinstalled in reversed position to provide fixed communication between certain of the passageways. Externally threaded nipples are provided for connecting the assembly to external fixtures, and resilient sleeves are inserted between the valve members and the body to form fluid tight seals.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
84 words
In a manifold assembly: a generally planar body fabricated as a unitary structure of a substantially rigid plastic material including a longitudinally extending rib and a plurality of laterally extending ribs intersecting the longitudinally extending rib, each of said ribs being formed to include an axially extending flow passageway, valve bores formed in the body at the intersections of the ribs and extending in a direction normal to the passageways, and valve members rotatively mounted in the bores for controlling communication between the passageways.
Claim 2
Dependent Claim
84 words
In a manifold assembly: a generally planar body fabricated as a unitary structure of a substantially rigid plastic material including a longitudinally extending rib and a plurality of laterally extending ribs intersecting the longitudinally extending rib, each of said ribs being formed to include an axially extending flow passageway, valve bores formed in the body at the intersections of the ribs and extending in a direction normal to the passageways, and valve members rotatively mounted in the bores for controlling communication between the passageways.
Claim 3
Dependent Claim
39 words
The manifold assembly of claim 1 further including sleeves fabricated of a material softer than the valve members and mainfold body disposed between the valve members and the walls of the bores to form a seal between the same.
Claim 4
Dependent Claim
29 words
The manifold assembly of claim 1 further including stop means carried by the manifold body and valve members for limiting the rotation of the valve members between predetermined positions.
Claim 5
Dependent Claim
15 words
The manifold assembly of claim 1 wherein the manifold body is fabricated of molded plastic.
Claim 6
Dependent Claim
41 words
The manifold assembly of claim 1 further including a mounting flange extending laterally from one edge of the body and clamp means carried by the flange for mounting the assembly on a support, said flange and said body being substantially coplanar.
Claim 7
Dependent Claim
100 words
In a manifold assembly; a body of rigid plastic having a generally planar wall, longitudinally and laterally extending ribs on one side of said wall, axially extending flow passageways formed in the ribs, valve bores formed in the body at the intersections of the ribs and extending in a direction normal to the passageways, valve members rotatably mounted in the bores for controlling communication between the passageways, and sleeves fabricated of a material softer than the valve members and the manifold body disposed between the valve members and the walls of the bores to form a seal between the same.
Claim 8
Dependent Claim
100 words
In a manifold assembly; a body of rigid plastic having a generally planar wall, longitudinally and laterally extending ribs on one side of said wall, axially extending flow passageways formed in the ribs, valve bores formed in the body at the intersections of the ribs and extending in a direction normal to the passageways, valve members rotatably mounted in the bores for controlling communication between the passageways, and sleeves fabricated of a material softer than the valve members and the manifold body disposed between the valve members and the walls of the bores to form a seal between the same.
Claim 9
Dependent Claim
26 words
The manifold assembly of claim 6 wherein the sleeves are constrained against rotation within the bores and the valve members are rotatably mounted in the sleeves.
Claim 10
Dependent Claim
123 words
In a manifold assembly; a body of rigid plastic having a generally planar wall, longitudinally and laterally extending ribs on one side of said wall, axially extending flow passageways formed in the ribs, valve bores formed in the body at the intersections of the ribs and extending in a direction normal to the passageways, valve members rotatably mounted in the bores for controlling communication between the passageways, and sleeves fabricated of a material softer than the valve members and the manifold body disposed between the valve members and the walls of the bores to form a seal between the same, said sleeves being inserted axially into the bores and including annular flange portions which abut against the outer face of the planar wall.
Claim 11
Dependent Claim
123 words
