Modular pneumatic control systems
First Claim
1. A fluid control apparatus comprising:
- a first fluid module defined by a body member having two substantially identical wall members, said wall members being arranged opposite each other;
a single cavity in said body member;
fluid regulator means in said cavity;
a fluid passage extending between a first wall and an opposing second wall;
a fluid input passage extending between said second wall and a third wall;
a fluid output passage extending between said first wall and said third wall;
with all of said fluid passages communicating with said cavity;
a second substantially identical second module adapted to be connected with said first module;
frictional fitment means integral with each module for connecting said modules together;
fluid coupling means for placement in and interconnecting an adjacent fluid passage of each body member, said coupling means also providing communication with said fluid passage which is nonadjacent to another fluid passage; and
plug or fluid coupling means for placement in an adjacent fluid input passage and output passage;
whereby said modules can operate as a stand alone fluid control apparatus without requiring any additional apparatus.

Abstract
A fluid module for a fluid control apparatus which has an internal fluid operated diaphragm which will permit the manifolding of several modules together. Each of the modules is of the same configuration and is interconnected to a common main fluid supply source. The modular units are plugged together using couplings with the main fluid source piped only to one device with an internal fluid passage delivering the fluid to all of the modular units. The modular units can be connected in a series or parallel combination with respect to signalling fluids. The modular units eliminate the cost of interconnecting different units at a variety of locations with different couplings as well as independently supplying each unit with a supply fluid.
