Each position allows the fluid to pass through the tubular body or not, one being a standby position, while the other is an active position. Inside the tubular body, a driver able to move the mobile element such that the mobile element passes from its standby position to the active position. The driver includes a pretensioned elastic device. Outside the tubular body, a device for maintaining the pretension connects to a controller able to deactivate the device for maintaining the tension.
