Abstract

Abstract A fluidic function module for constructing fluidic logical and/or analog circuit and which comprises a basic part including a plurality of fluidic circuit elements and a function connecting part which is arranged in contact with the basic part and in which passages have been formed which appropriately interconnect the input, output, supply and zero-pressure passages of the individual circuit elements, thus making the function module suitable for use as, for example, an AND, an OR, a universal or a storage module or as a function module having another desired function. The function connecting part is provided with a standard passage pattern. The user of the function module adapts the function connecting part to the intended use by removing, according to instructions given in tables, partitions from between different passages of the standard passage system and from between passages of the standard passage system and the ambient atmosphere at given grid locations and by subsequently assembling the function connecting part and the basic part to form a function module.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 126 words
A fluidic function module for constructing fluidic circuits for selectively performing logic, analog and combined operations, the function module comprising a basic part, the basic part comprising a plurality of separate fluidic circuit elements having input, output, air supply and vent passages; and a function connecting part provided with channels interconnecting the various input, output, air supply and vent passages of the individual circuit elements, an assembly of the basic part and connecting part forming a function module for selectively performing an AND, an OR, a universal and a storage function, the function connecting part being provided with a standard passage system having readily removable partitions between the channels and the passages of the standard passage system for adapting the connecting part to the selected function.
Claim 2
Dependent Claim 126 words
A fluidic function module for constructing fluidic circuits for selectively performing logic, analog and combined operations, the function module comprising a basic part, the basic part comprising a plurality of separate fluidic circuit elements having input, output, air supply and vent passages; and a function connecting part provided with channels interconnecting the various input, output, air supply and vent passages of the individual circuit elements, an assembly of the basic part and connecting part forming a function module for selectively performing an AND, an OR, a universal and a storage function, the function connecting part being provided with a standard passage system having readily removable partitions between the channels and the passages of the standard passage system for adapting the connecting part to the selected function.
Claim 3
Dependent Claim 37 words
Fluidic function module as claimed in claim 1, wherein the function connecting part is provided with readily removable vent partitions communicating with the passages and the ambient atmosphere for selectively venting the passages to the ambient atmosphere.
Claim 4
Dependent Claim 50 words
Fluidic function module as claimed in claim 2, wherein each of the readily removable vent partitions is in direct communication with a passage of the standard passage system of the function connecting part, and wherein a passage of the basic part opens into the passage of the function connecting part.
Claim 5
Dependent Claim 59 words
Fluidic function module as claimed in claim 1, wherein the standard passage system in the function connecting part includes at least one passage having an internal cross-sectional area which is appreciably smaller than are those of the remainder of the passages of the standard passage system, the passage having a smaller internal cross-sectional area serving as a fluid restriction.
