Title:
PRESSURE GAUGE AND PRESSURE GAUGE ASSEMBLY
Document Type and Number:
WIPO Patent Application WO/2007/026602
Kind Code:
A1
Abstract:
A pressure gauge (10) comprising a pressure measuring and indicating part (11)
for measuring a pressure and indicating it by an indication needle, a mounting
part (21) extending from the pressure measuring and indicating part and in which
a pressure detection passage (22) is formed, and an orifice member (60) disposed
in the pressure detection passage to form an orifice (62). Accordingly, the internal
mechanism of the pressure gauge is prevented from being damaged due to the fluctuation
of pressure. An orifice may be formed in a part of the pressure detection passage
in place of installing the orifice member therein. Further, a pressure gauge
assembly (1) comprises the pressure gauge (10) having the mounting part in which
the pressure detection passage is formed and joints (30, 40) connecting the mounting
part of the pressure gauge to a line. An orifice (49) is formed in a part of the internal
passage of each of the joints.
