Abstract
Abstract Manifold 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
123 words
In a manifold assembly: a generally rectangular body fabricated of molded plastic including a generally planar top wall, end and side walls extending from the top wall, a longitudinal rib adjoining the top wall and extending between the end walls in a direction generally parallel to the side walls, a plurality of lateral ribs extending between the side walls, axially extending flow passageways formed in ribs, the passageway in the longitudinal rib intersecting the passageways in the lateral ribs, valve bores formed in the body at the intersections of the passageways extending in a direction normal to the passageways, and valve members rotatively mounted in the bores having passageways adapted for selective alighment with the intersecting passageways for controlling communication between the same.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
42 words
The manifold assembly of claim 1 further including externally threaded nipples extending from the end and side walls of the manifold body and forming continuations of the passageways in the body for receiving fittings for connecting flow lines to the manifold assembly.
Claim 4
Dependent Claim
19 words
The manifold assembly of claim 2 wherein the nipples are formed as an integral part of the manifold body.
Claim 5
Dependent Claim
39 words
The manifold assembly of claim 1 further including sleeves fabricated of a material softer than the valve members and manifold body disposed between the valve members and the walls of the bores to form a seal between the same.
Claim 6
Dependent Claim
16 words
The manifold assembly of claim 4 wherein the sleeves are constrained against rotation within the bores.
Claim 7
Dependent Claim
15 words
The manifold assembly of claim 4 wherein the sleeves are fabricated of a polyurethane material.
Claim 8
Dependent Claim
41 words
The manifold assembly of claim 1 further including a mounting flange extending laterally from one side 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 9
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 10
Dependent Claim
54 words
The manifold assembly of claim 1 further including externally threaded nipples extending from the end and side walls of the body as an integral part thereof, said nipples being aligned with the longitudinal and lateral ribs and forming continuations of the passageways therein for receiving fittings for connecting flow lines to the manifold assembly.
Claim 11
Dependent Claim
42 words
The manifold assembly of claim 1 wherein each of the valve members includes a generally cylindrical core portion and an arcuately extending passageway formed in the periphery of the core portion for providing selective communication between the passageways in the manifold body.
