Abstract
A fluid pressure apparatus of this invention provides advanced control without imposing an excessive burden on a sequencer. When a plurality of fluid pressure apparatuses are connected to one another by manifolds, the individual fluid pressure apparatuses are provided with controller circuits each having a memory inputted with a control step, wherein each of the controller circuits activates each of control valves and a sensor based on an operating instruction issued from the sequencer to thereby execute processes such as confirmation of a controlled state, a trouble decision, etc.
Claims10
A fluid pressure apparatus made up of a complex assembly of fluid pressure devices mounted respectively on interconnected manifolds, comprising:
- a plurality of fluid pressure devices, said fluid pressure devices being of different types and serving different functions from each other;
- a plurality of manifolds, wherein said fluid pressure devices are mounted respectively on said manifolds, each of said manifolds having identical standardized side surfaces such that a side surface of one of said manifolds interlocks with a mating side surface on an adjacent manifold, said side surfaces including fluid connecting mechanisms for providing fluid connections between non-circular fluid passages in the respective manifolds and electrical connecting mechanisms for providing electrical connections between electrical terminals in the respective manifolds,
- wherein the fluid connecting mechanisms in one side surface comprise projecting connecting elements extending from and corresponding in shape to said non-circular fluid passages, and the fluid connecting mechanisms in another side surface comprise recessed connecting elements recessed into and corresponding in shape to said non-circular fluid passages and which are positioned and shaped for mating with said projecting connecting elements, and wherein a mating pair of said projecting and recessed connecting elements are non-circular in shape.
A fluid pressure apparatus comprising:
- a plurality of fluid pressure devices defined by respective blocks having respectively different functions, wherein said blocks are connected adjacently to each other, each of said blocks having a plurality of non-circular fluid passages therein, each of said blocks further comprising:
- a first joint surface having first fluid connecting portions extending from and corresponding in shape to said non-circular fluid passages, a first electrical signal connecting portion, and first block engaging means;
- a second joint surface having second fluid connecting portions recessed into and corresponding in shape to said non-circular fluid passages, a second electrical signal connecting portion, and said block engaging means;
- wherein the first joint surface of one block contacts the second joint surface of an adjacent block, said first fluid passage connecting portions, said first electrical signal connecting portion and said first block engaging means disposed on the first joint surface of said one block being shaped and positioned so as to interlock with said second fluid passage connecting portions, said second electrical signal connecting portion and said second block engaging means disposed on the second joint surface of said adjacent block,
- wherein said first and second fluid connecting portions and said first and second electrical signal connecting portions are non-circular in shape.
