Title:
The method and system which maintain a high vacuum in a vacuum box
Document Type and Number:
Japanese Patent JP5934239
Kind Code:
B2
Abstract:
The present invention provides a system (1) for maintaining a high vacuum comprising: a high vacuum pump (3) having an input (6) that is connectable to a vacuum enclosure (2) and an output (8); and a vacuum vessel (4) connected to the output (8) of the high vacuum pump (3). The vacuum vessel (4) of the present invention acts to maintain the output (8) of the high vacuum pump (3) within a suitable pressure range. This removes the need for the output (8) of the high vacuum pump (3) to be connected to a continuously operating vacuum pump. The system (1) of the present invention may further comprise a second vacuum pump (5) for maintaining the pressure within the vacuum vessel (4). A second vacuum pump (5) may need to be operated only intermittently when it is necessary to reduce the pressure in the vacuum vessel (4).
