Abstract
Abstract This invention relates to a circuit module for fluid distribution through which a source of fluid under pressure is connected to a plurality of logic control valve devices by means of passageways provided by interconnected cells or chambers formed in a moulded cellular plastic fluid circuit plate interposed between an upper and a lower flat cover plate, each provided with a plurality of passageways. Certain of these passageways in the upper cover plate open at one end into a corresponding cell or chamber in the circuit plate and at the opposite end registering with one end of a passageway in one of the logic valve devices, each of which is removably mounted on this cover plate. One or more passageways, each of any configuration, can be provided in the cellular plastic fluid circuit plate by removing a part of the plastic wall or partition between each adjoining pair of a plurality of pairs of the cells or chambers thereby providing for the flow of fluid from a source of fluid under pressure connected to a first one of the cells via a passageway in a manifold secured to the lower cover plate and a passageway in this plate, then successively through the other of the interconnected cells or chambers and the respective passageway in the upper cover plate to the logic valve device, or from the logic valve device through a passageway in the upper cover plate, another passageway provided by a second set of interconnected cells or chambers in the circuit plate to a second logic control valve device either mounted on the upper cover plate or located remote therefrom and connected to the manifold by suitable piping, or to atmosphere. The cover plates and the fluid circuit plate may be secured together either by a suitable bonding sealing material or a plurality of bolts and nuts and the logic valve devices may be removably secured to the upper cover plate by bolts that extend through these three members and receive a nut on their outer end. The cells or chambers in the moulded plastic fluid circuit plate may be hexagonal, triangular or any other desired shape, these chambers being separated one from the other by a thin plastic wall, a portion of which may be easily broken or cut out to provide a communication between any two adjacent chambers.
