Abstract
A fluid pulsator for a compressed gun (10) or water gun (30) is provided having a housing (604) with a fluid inlet (607) and a fluid outlet (608), an internal tube (605) reciprocally coupled to the housing, and a sealing member (606) reciprocally mounted to the internal tube. The housing and internal tube define a rearward pressure chamber (632) and a forward fluid pressure chamber (631). The fluid pulsator also has means for actuating the movement of the sealing member that can be manually manipulated to vary the actuation rate of the pulsator.
