PRESSURE REGULATOR IN SPRINKLER ELECTRICAL PUMP Russian patent published in 2008 - IPC A01M7/00 

FIELD: engines and pumps.

SUBSTANCE: pressure regulator is set to a specified fluid pressure so that if a fluid pressure exceeds the specified, the fluid pours out into a tank. The pressure regulator comprises case with a lower input vertical threaded aperture to hold an input sleeve; the said sleeve is screwed into an output branch of a force pipe of the electrical pump. Inside the case the input aperture is connected to a crosscut reach-through horizontal hole which relative to the input aperture is divided into an inlet hole on one side, and to a shut- off hole on another side; a regulated discharge valve is installed in the horizontal hole; at sprinkler clogging pressure exceeds the specified and the fluid is discharged into a tank; the fluid flows into the output lower aperture, located behind the discharge valve where a support with a gasket and a thrust screw are installed; a shock absorber is assembled between them; the shock absorber is adjusted to the electric pump fluid pressure. The inlet aperture is designed to feed fluid into a hose connection; the latter is secured to the pressure regulator case by means of the captive nut with gaskets.

EFFECT: simplification of a mechanized electrical pump design with a simplified pump regulator.
