REGOLAZIONE DI PORTATA - PAGINA 2

Filling system Vacuum generation Artificial heart
A proportional valve regulates the filling rate of the barrel until the barrel's desired weight is reached. The system allows for quick filling times and achieves an optimum balance between precision and weight. A modification of the inlet pressure at the vacuum generator via the proportional valve changes the vacuum generated. Blood is pumped through an artificial heart by alternately applying pressure or vacuum.
 
Volume control
A proportional volume valve continually regulates the water supply to the brush of a road sweeper.
