Title:
INSULATOR
Document Type and Number:
Japanese Patent JP2007071054
Kind Code:
A
Abstract:

To provide an insulator which simplifies a communicating structure and realizes space saving around an engine.

In an insulator 30, an accelerating pump mounting part 51 is provided to the lower part of a thermal insulation part 31. An acceleration pump 50 is mounted in the accelerating pump mounting part 51. A passage 41 is formed in the lower part of the thermal insulation part 31. A groove 42 for connecting an insulator air passage 32 and the passage 41 is formed in the connection surface 43 with the engine 1. A connection passage 61 for connecting the passage 41 and a negative pressure introduction chamber 70 is provided to an upper part of the acceleration pump 50. By so doing, the acceleration pump 50 can be easily arranged in a lower place of the insulator 30 which is originally a dead space. The need for external piping for communicating between the insulator 30 and acceleration pump 50 can be eliminated. Besides materializing space saving, as a result, a communicating structure can be simplified.
