ABSTRACT:
There is presented a slide valve assembly comprising an impulse tank adap to receive and retain fluid, under pressure and a fluid launch tube extending through the impulse tank, the fluid launch tube having openings therein adapted to be in communication with the impulse tank. The assembly further comprises a slide valve head slidably disposed in the impulse tank and adapted to move in the impulse tank between a first position in which the slide valve head covers the openings to prevent fluid flow between the impulse tank and the fluid launch tube, and a second position in which the slide valve head is removed from the openings to permit fluid flow between the impulse tank and the fluid launch tube. The assembly still further comprises a fluid flow resistance element fixed to the slide valve head and adapted, when covering the openings, to permit frictionally resisted flow of fluid therethrough.
