Abstract (en)
[origin: EP0676543A1] The valve includes a valve body (10) inside of which a piston(25) is connected to an actuator(23) and stopped from moving by a stop (30). During a first movement of the piston (25) from its position applied against the seat (27) it cooperates with stops (19) fixed on another piston (15), so as to move the first piston (25) in a direction, such that the second piston (15) moves away from its applied position against the seat (14). The actuator (23) regulates the flow of air by a first output (31) towards the air assisted injectors by regulating the position of the first piston (25) during its first movement. <IMAGE>
