Title:
INSULATOR
Document Type and Number:
WIPO Patent Application WO/2008/047435
Kind Code:
A1
Abstract:
An insulator (30) in which an acceleration pump fixing portion (51) is provided
at the lower part of a heat insulating section (31), and an acceleration pump (50)
is fixed to the acceleration pump fixing portion (51). A passage (41) is formed
at the lower part of a heat insulating section (31), a groove (42) connecting an
insulator air passage (32) with the passage (41) is formed in the connection surface
(43) with an engine (1), and a passage (61) connecting the passage (41) with a negative
pressure introduction chamber (70) is provided at the upper part of the acceleration
pump (50). Consequently, the acceleration pump (50) can be easilyarranged in
a space under the insulator (30), which has been essentially a dead space, and,
since external piping for allowing communication between the insulator (30)
and the acceleration pump (50) can be eliminated, space saving can be achieved
and the communication structure can be simplified.
