Embodiment Construction

[0029] A working fluid according to one embodiment of the present invention will be described below.

[0030] The working fluid of the present embodiment is used by being sealed in the liquid sealing space in the device. In addition, the working fluid of the present embodiment plays a role of transferring energy such as kinetic energy or thermal energy in the device, absorbing and weakening a load applied from the outside of the device, and the like, for example. And, in the device in which the working fluid is sealed in the liquid sealing space, the function required for the device is exhibited based on the above-mentioned action of the working fluid.

[0031] This working fluid is suitable for the following cases, etc.: For example, working oil sealed in an ink pressurizing mechanism of an inkjet printer, various hydraulic devices, etc., and flowing inside the device to transmit kinetic energy; sealing a liquid crystal for cooling a liquid crystal projector; Heat medium (su...

Abstract

The present invention provides a working fluid used in a liquid-enclosed space enclosed in a device, which includes a first liquid and a second liquid that are immiscible with each other, the content of the second liquid is less than that of the first liquid, and At the same temperature, the vapor pressure of the second liquid is higher than the vapor pressure of the main component of the first liquid.

Description

technical field [0001] The present invention relates to a working fluid used in a liquid-enclosed space enclosed in a device. This application claims the priority of Japanese Patent Application No. 2009-144620 for which it applied in Japan on June 17, 2009, and uses the content in this specification. Background technique [0002] It has been well known that, for example, in the vibration isolation device shown in the following patent document 1, the ink pressurizing mechanism of the inkjet printer shown in the patent document 2, etc., the working fluid is sealed in the whole device used in the liquid sealing space, when the liquid sealing When the hydraulic pressure in the space drops sharply, cavitation occurs in the working fluid in which air bubbles are generated. [0003] Patent Document 1: Japanese Patent Application Laid-Open No. 60-34541 [0004] Patent Document 2: Japanese Patent Application Laid-Open No. 5-64897 [0005] If cavitation occurs, then when the hydrau...
