ASSEMBLED SPRINKLER Russian patent published in 2018 - IPC A62C37/11 

FIELD: manufacturing technology.

SUBSTANCE: sprinkler comprising a housing having an inlet, an outlet and an inner passage extending from the inlet to the outlet, wherein the internal channel defines the longitudinal axis of the sprinkler and the nominal K-factor of at least 14.0 gpm / (psi)^½; sealing assembly disposed in the outlet opening to close the sprinkler outlet; fluid deflecting member remote from the outlet opening to a first axial distance, wherein fluid deflecting member is spaced from the outlet opening to a second axial distance; heat-sensitive rapid actuation trigger located and axially aligned along the sprinkler axis between the sealing assembly and the deflecting element, wherein the starting mechanism has a nominal thermal sensitivity and a nominal temperature threshold; and two frame arms extending distally from the body disposed around the heat-sensitive trigger mechanism and supporting the fluid-deflecting member at a distance from the outlet and the inlet, wherein each arm of the frame defines the surface profile in such a way that, thermal trigger is configured to operate on an activation event with a nominal thermal sensitivity and at a nominal temperature threshold, regardless of the activation event place of origin around the sprinkler axis. At that, each arm of the frame has a first section, passing parallel to the axis of the sprinkler, and a second section extending towards the axis of the sprinkler, wherein the first section having a side surface and a medial surface with respect to the axis of the sprinkler, wherein the first sections of the frame arms define cross sections, which are asymmetric with respect to each other with respect to the first plane bisecting the body, wherein in the first plane, the axis of the sprinkler is located; and wherein each cross-section is asymmetric with respect to a second plane intersecting the first plane and perpendicular thereto, wherein the axis of the sprinkler is located along the intersection of the first plane and the second plane, wherein the lateral surface of each first section comprises a waviness.

EFFECT: sprinkler device is proposed.
