Description

Valve assemblies for performing various logical functions

The invention relates to valve assemblies for performing various logical functions in one with a fluid logic circuit.

Various valve constructions are known, which essentially serve to fluid a Supply device or interrupt the supply of fluid, with the valves of the devices can be controlled directly.

According to P-PS 3 329 720 a simple valve is known which uses a movable ball to achieve a switching effect. Due to its construction, this valve is only suitable for supplying fluid or for interrupting a fluid flow. It cannot perform logical functions such as B. AND, NOT or STORE functions. It does not show a building block-like structure that would make it possible to get to a different valve by combining different building blocks.

In US Pat. No. 2,970,611 a valve is described which, like that according to F-PS 3,329, only serves to supply fluid or to interrupt the fluid flow, the particular object of the invention being to provide a valve which works very safely even when using fluids under very high pressure. The disadvantage of this valve is a very big expense dad is necessary to this valve reshape so that logic functions can be carried out, since no block-like structure is provided.

Fach of US-PS 3,080,887 and 3,175,581 pressure actuated multi-way valves are known. The valve according to US-PS 3,080,887 should work without friction and therefore uses membranes with a Multiplicity of valve seats cooperate. The valve according to US Pat. No. 3,175,581 has several plates that each interact with two valve seats. Both valves are used for supply and interruption from fluid flow to fluid pressure devices. You are not suitable perform logical functions. There is also no way to do this without much effort to redesign so that logical functions can be carried out. Furthermore, no concern was taken

to design the structure so that from a few recurring Building blocks different valves can be created, especially the location of Einlaßunu Outlet openings would be important.

According to US-PS 2 947 320 a valve is known which consists of a large number of thin,

standardized panels with openings, lamellar *

len and channels are equipped, must be assembled. Through various combination options Various valves can be produced from the plates, which certainly also have complicated functions can perform. The disadvantage, however, is that a very large number of different panels must be put together to make a functional Valve. In addition, skilled personnel who are familiar with complex logical systems would be required. if you wanted to create valves that logi ™ can perform functions. Special problems In terms of sealing, there are also pressure losses when using so many parts to be assembled to avoid.

The invention is therefore based on the object to provide valves that are used for control in with a Fluid, e.g. B. air or oil, operated logical

Circuits can be used, are simply »cheap and can be produced in large numbers and the Avoid disadvantages of the known valves. '

The object on which the invention is based is achieved in that the valve units consist of at least two essentially reohteokfönslgen, There are modular sized parts, clay which one is a base of the valve assemblies and the other an upper part of the valve assembly represents that the base at least one outlet opening and at least having an inlet opening, that the upper part has a passage leading from an inlet opening in

the base leads to a flexible membrane that is inserted into the Valve units are arranged between the upper part and the adjoining valve part and can thus be deflected, that they have logical functions with respect to other openings

According to a further training, gowns are provided, which hold the parts of the valve assemblies together. Preferably these means are screws that through one: s of the parts of the valve assemblies protrude and are screwed into the other, and are located Nuts on the screws: s,. the valve assemblies stick together.

At this moment the outlet valve closes because the contact surface 90 is in contact with the outlet valve 92. The operating or Vunktlonslago is shown in Schcawitisch in Fig. 7.

opening 154. The one on the left in Pig. The ÜND module shown in FIG. 35 therefore only delivers pressure to the outlet opening 154 when both the inlet opening 164 and the inlet opening 162 are pressurized. It is important to note that the AND module can perform a "snap action" because,

after the pressure at the inlet port 162 becomes sufficiently large, the valve pin 182 moves extremely quickly downward .

The timer module or the CLOCK valve according to the present invention can be used to acquire veraehiedenster functions as may be required in an operating with a fluid logic circuit.

The arrangement can be used to terminate pressure pulses and also to have them begin using the timing module in conjunction with a NIGHT module of the type described in FIGS. 13-18.

From the preceding description it follows that the valve assemblies according to the invention are relatively simple and can perform the most varied of functions, such as OR, AND, NOT, MEMORY, DIFFERENTIATOR or CLOCK functions. Each valve has a minimum of parts and each is very easy to assemble. .
