Patent ID: 8408228

Claim:
A flow control device for a sprinkler, comprising: a. a body/connector partially placed within said sprinkler with means for guiding a sliding cord and with a predetermined inner major diameter defined by a sealing surface, b. a sliding cord that connects a stopper and a sealing device, and said sliding cord, with the assistance of the flow from the fluid, glides freely up and down within the said body/connector and the sprinkler, c. said sealing device formed as a single spheroid shape member that cooperates with said sealing surface of said body/connector during abnormal operational conditions and said sealing device is directly attached to the lower end of said sliding cord, d. said stopper formed as a single spheroid shape member that is attached to the upper end of said sliding cord, whereby said stopper is in contact with the internal undersurface of said sprinkler head thus preventing said sealing device from sitting against said sealing surface of said body/connector during normal operational conditions.
