Title:
改良ブレーキ速度ヒューズ
Document Type and Number:
Japanese Patent JP4772184
Kind Code:
B2
Abstract:
An improved the velocity fuse valve (118) controls communication between first and second brake valves (14, 16) and first and second brake lines (20, 22). The velocity fuse valve (118) includes a valve housing (200) having a valve bore (202), which slidably receives a valve spool (204). The spool (204) moves in response to pressure in first and second pilot chambers (222, 226), each communicated with a corresponding first and second outlet (128, 130). The first pilot chamber (222) is communicated with the first outlet (128) via a first dashpot passage (164) and a first orifice (166), and the second pilot chamber (226) is communicated with the second outlet (130) via a second dashpot passage (160) and a second orifice (162). The orifices (162, 166) reduce or control how fast the spool (204) will move in response to the pressure differential between the pilot chambers (222, 226).
