All of the air coming from the electric pump is delivered into the reservoir. The electric pump () is activated by the pusher () as soon as it leaves its high rest position, and the outlet valve () is opened only in the proximity of the low depressed position, such that the electric pump () is electrically powered before the outlet valve () is opened and delivers air into the reservoir () with an increase in pressure that is less than 1 Bar.
