Diaphragms

Diaphragms are low energy loss, full-sealing elements. They are used as highly sensitive, flexible partitions between two chambers containing variable volume. variable pressure fluids.
By using diaphragms instead of more traditional sealing units such as O-rings and lip seals, the following advantages can be obtained:

1. Total sealing performance
2. No sliding friction
3. No lubrication requirements
4. High sensitivity
5. No stick-slip friction
6. Low hysteresis

1. Ridotta isteresi

Esistono tre tipi fondamentali di membrane :

1. 1. Membrane stampate in sola gomma
   2. Membrane convolute e a rotolamento rinforzate con inserto tessile.
   3. Membrane ricavate per fustellatura da tessuto gommato
      1. 1. Piane
         2. sagomate

Il tessile assolve alla funzione di rinforzo “armando” la membrana e conferendole quindi la resistenza a pressioni di esercizio pneumatiche o idrauliche relativamente alte ,entro una estesa gamma di temperature e di corse.
