Abstract

PURPOSE:To obtain a high vacuum by a method wherein a solution is utilized as a driving liquid instead of water. CONSTITUTION:In case the solution of ethylene glycol is utilized instead of water as the driving liquid, a suction vacuum may be obtained until the vapor pressure of water in each temperatures by reducing the temperature of the solution to a temperature below 0 deg.C. In case organic or inorganic liquid such as saline solution of some concentration, low viscosity oil or the like except ethylene glycol, which are not frozen at a temperature below 0 deg.C, is utilized, the vacuum at least below 6-7Torr, in some case the same near 1Torr, may be obtained by the suction of the pump.

〜７Ｔｏｒｒｊ、；ｊ。DETAILED DESCRIPTION OF THE INVENTION This company has been interested in a liquid injection pump characterized by using an aqueous solution instead of the driving water of the conventionally used water jet pump to lower the ultimate vacuum degree. Water bombs or water injection pumps have been used to draw condensable gases in relatively low vacuum areas. The only moving part of this pump is the driving water pump, and it has been used relatively easily. However, when water is used as a driving liquid, there is an effect such as air dissolved in water, and the driving water can only suck up to the temperature of vapor H plus a pressure of several Torr. 1 wealth, and if you try to suction with 6 to TTOrr nail side 1, you have to remove the driving water at 1 near O'C, and depending on the case, there is a risk of freezing of the driving water. be. If water 2 is used as the driving liquid, 0t is 6 due to the above reason.
