Patent ID: 8453658

Claim:
A pressurized progressing spray device suitable for serial placement comprising: a fluid supply inlet; a supply bypass outlet in selective fluid communication with said fluid supply inlet whereby a connection to a fluid supply inlet of another pressurized spray fitting can be achieved, either directly or through a selected conduit; a spray channel in selective fluid communication with said fluid supply inlet; a spray directing mechanism connected to said spray channel, wherein said spray directing mechanism travels from an initial position to an end position when driven by fluid pressure; a first trap door operable to establish a seal between said fluid supply inlet and said supply bypass outlet when in its closed state; and a second trap door operable to establish a seal between said fluid supply inlet and said spray channel when in its closed state, wherein said second trap door is connected to said first trap door such that said first trap door is always in the opposite state of said second trap door; and a damper component connected to said spray directing mechanism which slows the travel of said spray directing mechanism between said initial position and said end position, wherein said first trap door is triggered so as to switch it from its closed to its open state upon said damper component reaching said end position.
