Title: Method and device for adjusting pressure by use of heat medium
Inventor: OOIZUMI TOMOSUKE
IPC: F25B1/00
Filed: 1992-02-20
Abstract: PURPOSE:To prevent gas from leaking and thereby eliminate the use of a pressure adjusting solenoid valve by filling a closed tank with a fluid or vapor of a heat medium and, when vapor pressure in the closed tank is raised or lowered owing to the expansion or contraction of the heat medium caused by heating or cooling in a heat medium piping system cooling or heating the vapor, CONSTITUTION:A cooling apparatus comprises a heat medium piping system 3 composed of a pump 4, a loading cooling coil 5, and of a refrigerating apparatus 6, and a closed tank 7 which is connected with the heat medium piping system and is filled with a fluid L and vapor H of a heat medium 2. In the closed tank 7, a condenser 9, a heater 11, and a pressure sensor 10 for detecting the pressure of the vapor H are provided. A fluid surface in the tank 7 is raised owing to the expansion of the heat medium 2 as the temperature of the heat medium 2 is raised by heating the inside of the heat medium piping system 3, and thereby the pressure of the vapor H is raised. This is detected by the pressure sensor 10 to actuate the condenser 9 for cooling. Reversely, when the temperature is lowered to result in pressure lowering, the heater 11 is actuated. The pressure of the heat medium 2 in the heat medium piping system 3 is kept at predetermined pressure to eliminate the use of a solenoid valve.

Abstract: PURPOSE:To prevent simply and effectively clogging of an ink jet recording device due to drying and hardening of the ink and other causes by covering the nozzle section of an ink jet head with an ink evaporation preventive liquid after charging air foam into the nozzle section during stopping ink injection. CONSTITUTION:Firstly, after the valve 11 of an ink jet recording device is closed to stop injection of the ink, the valve 12 is opened at once to put air foam 20 into the inside of the ink jet head 1 to develop an ink film 21 over the hole section of the nozzle 2. Next, the pressure of the ink in the head 1 is raised a little to expand the ink film 21 outwardly, and this ink film 21 is washed away by applying an ink drying preventive liquid (preferably wetting agent constituting the ink). Furthermore, by lowering the ink pressure in the head 1 to its original pressure, the ink film 21 is substituted for the film 22 of the ink drying preventive liquid to prevent clogging of the ink. EFFECT:Reliability of the device is improved in a great deal.
