CHANNEL SHUTOFF DEVICE Russian patent published in 2019 - IPC F16K3/26 

FIELD: machine building.

SUBSTANCE: proposed channel shutdown device relates to machine building hydraulics and can be used in systems providing thermal conditions of rocket and space equipment, as well as in other fields of engineering. Device includes housing with blind cylindrical cavity and perpendicular to cross its cylindrical channel. In the cavity there is a slide installed with two parallel holes. In one hole there is a cylindrical plunger equipped with one end of the lead-in chamfer, and actuating shaft. Actuating shaft is rigidly mounted in the plunger perpendicular to its axis, and slider between adjacent to the inlet opening of the cylindrical cavity hole and end face of the slider is a through slot, actuating shaft passes through the slot. Device also comprises lead screw screwed into threaded hole at slider end face.

EFFECT: technical result achieved using the claimed invention is expansion of the device usage capabilities.
