Abstract
Un sistema de valvula (10) que emplea un elemento piezoelectrico (38) para activar una valvula de flujo de fluido (18) para utilizar una cantidad minima de energia electrica. El elemento piezoelectrico (38) activa una valvula de presion piloto (36) que permite que un fluido de control pase a una valvula de control principal (44). El fluido de control provoca que la valvula de control principal (44) active un elemento de trabajo (16) que a su vez opera la valvula de flujo de fluido (18). Una estructura de conmutacion (70) se emplea para activar el elemento piezo electrico (38). La estructura de conmutacion (70) puede incluir diversos tipos de dispositivos de conmutacion tales como dispositivos de conmutacion de RF, dispositivos de conmutacion optica, dispositivos de conmutacion infrarroja y dispositivos de conmutacion electrica de bajo voltaje.
