Abstract:
A dry sprinkler includes a flexible tube section that maintains a pressurized fluid, such as a liquid antifreeze solution, between a first end and a second end. A first seal prevents fluid from a supply line from entering the flexible tube section. The first seal is maintained in a sealed position by a pressure of the pressurized fluid. A sprinkler head is coupled to the second end of the flexible tube section, and includes a frame, an output orifice, a deflector, a second seal that seals the output orifice, and a thermally responsive element configured to maintain the second seal in a sealed position when the thermally responsive element is in a non-responsive state. A differential pressure controller maintains a ratio between the pressure of the pressurized fluid in the flexible tube section and a pressure of a supply fluid in the supply line to at least a certain ratio.

Claim (Index 1):
A dry fire protection sprinkler comprising:\n (A) a fitting having (a) an inlet end configured to connect to a fluid supply line, (b) an inlet orifice, and (c) an outlet end; (B) an inlet seal assembly configured to seal the inlet orifice of the fitting; (C) a flexible tube (a) having (i) an inlet end connected to the outlet end of the fitting, (ii) an outlet end, and (iii) a valve opening, and (b) configured to contain a pressurized fluid; (D) a sprinkler frame connected to the outlet end of the flexible tube, and having an outlet orifice; (E) an outlet seal assembly configured to seal the outlet orifice of the sprinkler frame; (F) a thermally responsive element provided between the sprinkler frame and the outlet seal assembly, and configured to (a) fail when ambient temperature reaches a predetermined temperature, and (b) to hold the outlet seal assembly in the outlet orifice until failing; (G) a control valve connected to the valve opening of the flexible tube, and configured to open and to close; (H) a pressurized fluid source connected to the control valve and configured to supply the pressurized fluid to the flexible tube when the control valve opens; (I) a flexible tube pressure sensor configured to measure a pressure of the pressurized fluid in the flexible tube; (J) a fluid supply sensor configured to measure a pressure of a fluid in the fluid supply line; and (K) a differential pressure controller connected (a) to the control valve, (b) to the flexible tube pressure sensor, and (c) to the fluid supply pressure sensor, and, when a difference between the pressure of the pressurized fluid in the flexible tube and the pressure of the fluid in the fluid supply line is less than a predetermined ratio, the differential pressure controller sends a signal to the control valve to open in order to allow the pressurized fluid to enter the flexible tube, and, when the difference between the pressure of the pressurized fluid in the flexible tube and the pressure of the fluid in the fluid supply line equals the predetermined ratio, the differential pressure controller sends a signal to the control valve to close.
