Abstract

The control valve disclosed comprises a hollow outer element (4), stopped at one end and fitted with a silencer (18) at the other and incorporating two air inlet ducts, one normally open, one for control, and two outlet ducts, also, an inner element (7) with an axial bore capable of fluid-tight movement within the outer element, and a piston (15) likewise mobile and fluid-tight internally of the inner element; air supplied to the control inlet causes the piston (15) and the inner element (7) to shift from an at-rest position, toward which they are biased by a spring (14) so that air exhausts by way of the one outlet, into an operative position in which the air exhausts by way of the other outlet.
