DEVICE FOR DISCHARGING POURABLE MATERIAL FROM CLOSED SPACE BY MEANS OF GAS OF OVER-ATMOSPHERIC PRESSURE.

摘要

discharge device of a material that can be poured from an enclosed space through a gas at a pressure greater than atmospheric pressure, with a reservoir of the material.a container of gas, an envelope surrounding, at least partially, the reservoir of material.a piercing needle connected to the casing and used to open the container material, and an actuating device for opening and closing the discharge device, and related to the orithe reservoir of material benefit.the device is characterized in that it has a passage connecting the interior of the gas container and the reservoir of material during the operation of the device.as well as end plates closing the passage in a non operating condition.the device herein described has the advantage that it can be produced and operated easily and economically, and spraying, and the extraction pressure, respectively.a variety of substances that may be used without the risk of environmental pollution and accidents.
