REGULATOR Russian patent published in 2009 - IPC F16K3/02 F16K31/52 F16K47/02 

FIELD: transportation.

SUBSTANCE: in regulator, unloading rod is located at side opposite to actuator rod. The latter is connected with flat slide gate. In the body behind the seat and in axial alignment with it, identical seat with installed in it flat slide gate having hole and insert is located. The latter are turned by 180 degrees and installed being able to move toward flat slide gate. Flat slide gate at unloading rod side is connected with identical unloading rod, and at actuator side it is connected with additional unloading rod. Diametres of rods are equal to actuator rod diametre. Arms of equal-armed rocker are located in the grooves of both unloading rods. The latter is rotatably mounted on the axis. In the body behind each seat in axial alignment with orifice flow divider is mounted forming cavity. The latter is made as perforated cylinder with blind baffle in the middle. Baffle is made as circular cones. Vertexes of cones are located on cylinder axis at both sides. Cylinder holes on both sides of baffle communicate through cavity. Total area of holes on both sides of cylinder is not less than area of seat orifice.

EFFECT: reliability improvement and increase in durability of regulator operation.
