Abstract
Abstract A valve manifold and a modular valve which may be used in the assembly thereof or used separately therefrom. When the valve is mounted in any one of four positions, four different combinations of functions are possible. No additional parts are required to mount the valve in any of the four positions. All valves may be identical or some may be normally open and some normally closed. Half O-ring grooves permit the use of two positions. Mounting symmetry is required in any case. Two seals permit either pneumatic or hydraulic use. Tandem operation of two valves with a single solenoid is accomplished through the use of rods slidable through the valve body. Higher pressure ratings may be achieved in alternative embodiments.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
374 words
A modular three-way valve manifold comprising: a plurality of valve bodies each having two substantially flat and substantially parallel mateable opposite sides, each of said opposite sides of each body having spaced first and second ports therein, first passage means connecting both of the first ports in each body, second passage means connecting both of the second ports in each body, third passage means connected from said first passage means in each body, fourth passage means connected from said second passage means in each body, a cylinder port through a side of each body other than said opposite sides thereof; a first valve connected from said third passage means to said cylinder port in each body; a second valve connected from said cylinder port to said fourth passage means in each body, one of said first and second valves in each body being normally closed, the other of said first and second valves in each body being normally open; assembly means for each body independently operable to actuate and to deactuate said first and second valves in each respective body simultaneously in a manner to move each said one valve to its open position while the other valve in the same body is moved to its closed position, and vice versa, said first ports of each body having a common bore axis normal to said opposite sides, said second ports of each body having a common bore axis parallel to that of said first ports; at least one O-ring like fluid tight seal clamped between two of the said opposite sides of two different respective bodies, one of said two bodies having one first port bore axis common to that of one of the first and second ports in the other of said two bodies, said one body having its second port bore axis common to that of the other of said first and second ports in the other of said two bodies, said seal being located around one pair of facing ports in respective ones of said two bodies; and means to clamp said bodies together in a manner such that said one first port in said one body faces any one of the four first and second ports in said other body.
Claim 2

A modular three-way valve manifold comprising: a plurality of valve bodies each having two substantially flat and substantially parallel mateable opposite sides, each of said opposite sides of each body having spaced first and second ports therein, first passage means connecting both of the first ports in each body, second passage means connecting both of the second ports in each body, third passage means connected from said first passage means in each body, fourth passage means connected from said second passage means in each body, a cylinder port through a side of each body other than said opposite sides thereof; a first valve connected from said third passage means to said cylinder port in each body; a second valve connected from said cylinder port to said fourth passage means in each body, one of said first and second valves in each body being normally closed, the other of said first and second valves in each body being normally open; assembly means for each body independently operable to actuate and to deactuate said first and second valves in each respective body simultaneously in a manner to move each said one valve to its open position while the other valve in the same body is moved to its closed position, and vice versa, said first ports of each body having a common bore axis normal to said opposite sides, said second ports of each body having a common bore axis parallel to that of said first ports; at least one O-ring like fluid tight seal clamped between two of the said opposite sides of two different respective bodies, one of said two bodies having one first port bore axis common to that of one of the first and second ports in the other of said two bodies, said one body having its second port bore axis common to that of the other of said first and second ports in the other of said two bodies, said seal being located around one pair of facing ports in respective ones of said two bodies; and means to clamp said bodies together in a manner such that said one first port in said one body faces any one of the four first and second ports in said other body.
Claim 3
Dependent Claim
93 words
The invention as defined in claim 1, wherein said bodies have a plurality of bolt holes therethrough parallel to the corresponding bore axes of the first and second ports of each respective body, said holes being symmetrical about a first predetermined plane, said first plane passing through the bore axis of said first and second ports, said holes also being symmetrical about a second plane perpendicular to said first plane and located midway between the bore axes of said first and second ports, and bolts extending through said holes clamping said bodies together.
Claim 4
Dependent Claim
61 words
The invention as defiNed in claim 2, wherein each body has two annular grooves concentric with each bore axis extending around both of said first ports and both of said second ports in spaced relation thereto, each said groove having a depth equal to about one-half of the small O-ring diameter, all mating ones of said grooves having an O-ring therein.
Claim 5
Dependent Claim
101 words
The invention as defined in claim 1, wherein at least one said opposite side of said one of said bodies is clamped against one said opposite side of said other of said bodies, said one body one side having two annular grooves therein concentrically spaced from said ports therein, said other body one side having two annular grooves therein to mate with said one body grooves, respectively, to form two closed annular volumes, said seal being provided in one of said volumes, another seal being provided in the other of said volumes, said seals each being a resilient O-ring in compression.
