ABSTRACT:
An improved high pressure impulse valve includes a pilot section, an intermediate section, and an output section which are pressurized to approximately equilibrium with the inlet pressure during a load portion of the operating cycle and which cooperate to provide extremely rapid full opening of the output section to release fluid under pressure from an accumulator through an output section piston seat. The valve is particularly suitable for use in combination with pneumatic impulse separation systems such as those employed for deicing aircraft surfaces.
