Synthetic resin spray pistol - has mixing chamber formed by punch cavity and emits round or flat jet

摘要

The pistol consists of a body containing a block or punch with a cavity forming, with the body, a mixing chamber. Pneumatic devices mix the products arriving in this chamber under pressure, and a spray jet allows spraying in a round or flat jet. The body can have a blind taper bore in which the block or punch fits. The cavity in the latter can be in the form of an axial bore with a bell-mouth opposite the base of the blind taper bore, and it can also have a peripheral groove, opposite which compressed air is delivered through perforations. The punch can be secured to the body by a bayonet coupling.
