FIELD: test equipment.SUBSTANCE: ejection device includes a receiver, a high pressure gas source with a start-up system, and valves. High pressure gas source is installed so that gas can enter the receiver cavity. Valves are installed in the receiver housing. A cylindrical shell is attached with its bottom surface in installation place of each valve on the outside to the receiver so that gas can flow through the valve to its cavity. Each valve is equipped with a stock and a piston, which are arranged inside cylindrical housing with a closed end face. One of the stock ends is made so that is goes tightly through a closed end face of the valve body so that it can be borne against the appropriate ejected object. Piston has the possibility of fixing the specified distance relative to the end face of the valve body and is equipped with symmetrically located through holes. In side wall of the valve body between end faces of the valve body and piston there are symmetrical through holes, the total area of which is larger than or equal to total area of holes in the piston. Distance from inner surface of end face of the valve body to its farthest surface of the hole in side wall of the valve body is smaller than the piston height.EFFECT: achieving the possibility of group ejection of several objects at specified speeds.3 cl, 3 dwg |
