Abstract
Servomotor with reduced idle stroke of actuation without decrease in valve lift on release of the brake. According to the invention, the rest position of the actuating rod 36 is determined by movable stop 60 capable of withdrawing on release of the brake in order not to impede lift of the valve poppet 32 relative to the seat 40, which allows, in the rest position, these two elements to be brought closer with a short distance d, thus reducing the idle stroke of actuation. Application to power-assisted braking.
